Softmax | softmax.com | San Francisco (onsite) | Full-time

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E

Apple | Software Engineer - Developer Tools/LLDB | London, UK | ONSITE (3 days/week in office)

The LLDB team is hiring an engineer to work on the debugger, which is used internally across Apple and externally by millions of developers. You'll drive features and improvements in LLDB, collaborating across teams working on the OS and toolchain. Responsibilities range from supporting new hardware and platforms to developing debugging features, with most work open-source (llvm.org & swift.org).

If you're passionate about developer tools with experience in system-level programming and knowledge of compiler/debugger/OS internals, we'd love to hear from you!

https://jobs.apple.com/en-gb/details/200643284/debugger-engi...

This is weird but I am required to create an Apple account to apply for this job. And I cannot create an Apple account, I just end up at an unhelpful page which says that this task cannot be done at the moment. I've tried tons of alternatives, but nada. It seems like the only way to 'recover' my account (I don't wanna recover!) is to do so from an Apple device, which I don't own!

Hello. I have 10 years of compilers experience and I've applied months ago but haven't heard back yet (but also not rejected). Is it possible to reach out to you directly?

Lead Full-Stack Engineer Marker Learning | Remote (U.S. only) | Full-time | Engineering | 185-250k

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your resume and why you want this position to lucie@markerlearning.com. Make the subject "Lead Engineer Application (I am not a bot)".

This post says remote, but then Greenhouse for the manager says it requires to be in NYC.

Would a Canadian candidate be considered?

I was previously manager at several monetization teams at Asana.

Hi flockonus, listing should say NYC preferred but we're certainly open to remote. In fact, we have three EMs in Canada between Toronto and Vancouver.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

We’re a start-up company, we are building a local-AI camera OS that replaces cloud CCTV: SigmaStar cameras → RTSP/ONVIF → HDMI node → on-device AI (offline-first).

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)

We already run RTSP + inference. Now we need the person who owns several year device reality.

You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

Competitive salary, flexible working environment & location, if you are interested, feel free to email: ayeeye.careers@gmail.com (subject: “HN – Role”)

Let me know when you need sales/marketing/channel ownership.

Thanks, will keep you updated.

We're building AI that predicts whether a wounded soldier survives — before they reach a hospital.

LIFEGUARD Technologies is hiring an ML Research Engineer to build a multimodal CNN-LSTM wound trajectory engine from scratch, on unique real-world conflict wound data — video and clinical time-series — that exists nowhere else.

This is a government-funded programme with a clear 28-month roadmap, taking the system from proof-of-concept to a field-demonstrated prototype operating offline on hardware. You will own the technical core end to end — multimodal architecture design, XAI integration, edge deployment, federated learning across geographically separated data nodes, and regulatory documentation to UK standards.

The work is hard. The scope is real. The data is irreplaceable. You may see the front line.

For the right engineer, there is also a broader opportunity across a portfolio of health and med-tech ventures — building AI that saves lives across oncology, defence medicine, and emergency care.

What we're looking for: proven CNN and LSTM / Transformer experience on clinical or scientific time-series; multimodal fusion experience (image + structured data) a strong advantage; hands-on PyTorch, ONNX Runtime, and XAI (SHAP/LIME/Captum); ability to work directly with clinicians. PhD or MSc preferred. UK SC clearance eligibility preferred but not a requirement.|

£70,000 – £85,000 base. 0.5%–1.0% EMI equity. Remote/hybrid UK.

What do y'all think about the latency/quality tradeoff with LLMs?

Human voices don't take 30 seconds to think, retrieve, research, and summarize a high quality answer. Humans are calibrated in their knowledge, they know what they understand and what they don't. They can converse in real time without bullshitting.

Frontier real time-ish LLM generated voice systems are still plagued by 2024 era LLM nonsense, like the inability to count Rs in strawberry. [1]

I'd personally love a voice interface that, constrained by the technology of today, takes the latency hit to deliver quality.

Not affiliated with Sesame, but this is what the realtime models are trying to solve. If you look at NVIDIA’s PersonaPlex release [0], it uses a duplex architecture. It’s based on Moshi [1], which aims to address this problem by allowing the model to listen and generate audio at the same time.

Herakles Defense | Munich, Germany | REMOTE| Full-time | Part-time available

Here's the problem: A small drone flies at you at 60mph / 100 km/h You have a camera, one edge processor, and must detect, classify, and track it at 30fps — against sky, trees, buildings. Starting from 100+ meters. If your pipeline drops a single frame at far range, the intercept fails. Sounds impossible? We think together we can solve this.

Now the second problem: Your guidance law needs to predict where that target will be in 0.5 seconds, compute the intercept geometry, and command the flight controller — with noisy IMU data, wind gusts, and a target that doesn't fly in straight lines. No GPS. No RF link. Just onboard compute.

We solved the guidance part in simulation. Our IBVS pipeline tracks and hits moving targets in SITL. The hardware prototype is built and ready. But the real engineering starts now.

We need:

* Computer Vision & Edge AI Engineer — YOLO on Jetson/Hailo/QRB5165. Detect, classify and track small targets at 100m+. Model pruning, TensorRT, sensor fusion. If you've pushed edge hardware to its absolute limits, this is your problem.

* GNC / Flight Systems Engineer — Image base visual servoing, proportional navigation, EKF/UKF state estimation, PX4 integration. Take what works in sim and make it survive real-world sensor noise.

* Simulation & Test Engineer — SITL/HITL, Monte Carlo campaigns, digital twins. 10,000 simulated engagements before anything leaves the ground.

* Technical Advisors — Drone warfare, GNC/aerospace, defense procurement. A few hours/month from the right person changes our trajectory.

We're a pre-seed defense startup in Munich building autonomous interceptor drones to stop FPV kamikaze drones. 2 founders. Salary + equity. No AI screening — we read every application.

Deep Systems | Senior DevOps Engineer | Remote EMEA, APAC, and Americas | Full-time

I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.

You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.

Capital markets / FIX experience is a plus, not a requirement. Appetite for learning is.

The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.

Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.

LiveEO leverages high-resolution satellite imagery and AI to provide actionable insights across industries—like protecting power grids, monitoring critical infrastructure, and ensuring deforestation compliance.

We are looking for a Senior ML Engineer to build and scale multitemporal, multimodal computer vision models for Earth observation. You’ll combine optical and Synthetic Aperture Radar (SAR) data into robust representations. This role is a true balance of applied research and engineering: you’ll own the full ML R&D lifecycle from data standardization and SOTA model development to rigorous evaluation and production-grade delivery.

Tech Stack: Python, PyTorch/Lightning, Databricks, MLflow, Ray, Prefect, AWS, Geospatial stack (GDAL, Rasterio, GeoPandas, STAC), PostgreSQL.

What we're looking for:

* Strong Python engineering and deep PyTorch/Lightning experience.

* Proven experience implementing and training deep learning models at scale.

* Hands-on experience with satellite imagery (optical & SAR strongly preferred).

* Strong CV fundamentals (representation learning, supervision, evaluation) and ML experimentation (Databricks/MLflow).

* Pragmatic mindset: you can take SOTA papers to validated baselines and production under real-world constraints.

Must be living in or willing to relocate to Berlin. This role requires German/European citizenship due to legal/regulatory requirements.

(Bonus points for experience with large-scale geospatial foundation models, VLMs, or distributed compute with Ray).

Apex Dental Partners | Full-Stack Developer | Dallas, TX (Remote US or Hybrid) | apexdp.com

We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Decise | Principal Engineer & Technical Strategist | Remote (US) | Fully Remote | Contract (1099)

Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.

We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.

Our clients rely on us to turn complex business problems into working systems — not slide decks.

We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.

White-glove service. Blue-collar grit.

We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.

Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.

Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.

This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.

The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

Apply here: https://jobs.ashbyhq.com/mobasi/b385d2bb-d338-44cc-8728-f0eb...

The stack you're describing (multi-cloud Terraform across AWS/GCP/Azure handling law enforcement evidence) is genuinely complex to secure from the ground up — especially with the compliance exposure that comes with CJIS-adjacent data.

One thing worth thinking about before the new hire starts: the first infra person at a bootstrapped company almost always walks into cloud credentials that are broader than needed and Terraform state that's never had a security pass. Getting a baseline done before onboarding gives them a clean starting point and avoids inheriting someone else's decisions as their first task.

Happy to talk through the infra side if useful — I work with teams at this stage on exactly this.

Multi-cloud Kubernetes at scale (AWS + Azure simultaneously) is one of those setups where IAM boundaries and secrets management tend to drift faster than the team realizes — each cloud has its own identity model and they don't map cleanly to each other, so the blast radius from a misconfigured service account is usually larger than anyone expects.

Worth doing a security pass on the existing setup before new platform engineers inherit it as the baseline. Distributed teams expanding across regions amplify this fast.

Happy to talk through the infra security side if useful — this is the kind of work I do with teams at this stage.

We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from Balderton, XTX Ventures and leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.

Fractional AI | Senior/Staff Software Engineer | SF, NY, NC, Dubai | Onsite

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll hopefully be the first to know about it.

We’re hiring SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly (frank@fractional.ai) or take a look at the full job posting:

RINSE | REMOTE or San Francisco, Los Angeles, Chicago, Boston, New York, New Jersey, Seattle, Austin, Toronto, or Washington DC | Software Engineer | Full-Time | Salary: $80k-$200k USD | https://www.rinse.com

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.

Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.

We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.

We're particularly interested in someone with significant React Native expertise at the moment, as we work to improve the apps our customers, delivery valets, and partners use.

You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Do you have offices in all those cities, or why are you listing them? I will downvote your and all other posts who do this unless you reply, because I think you are doing this to appear when people search for specific location.

We do have a physical footprint in each of those cities, and there is real value in being able to actually see our product and service in person by being in our service area. We can provide a desk with real co-workers in any of those cities.

Most developers prefer to work from home, though! We're fully remote, and are free to mostly work from home or a co-working facility instead of one of our potentially-noisy offices.

Am I crazy if I hate remote?

I don't make the rules here, so I am going to remove the downvote, but I believe there should be a way to easily search for jobs that aren't remote.

I appreciate your response.

edit: I can't remove it anymore
