We're building the world's first commercial stellarator fusion power plant. First spin-out from the Max Planck Institute for Plasma Physics, based on Wendelstein 7-X (the largest stellarator ever built), €650M+ raised, teams in Munich, Zurich and Oxford.
Finding a good stellarator design means searching an enormous high-dimensional space, and every candidate design needs heavy plasma physics simulation. That's the compute problem this role owns: cloud + HPC clusters, K8s, Ray, Dask, and the platform work around it (CI/CD, IaC, observability).
You'd sit directly next to the physicists and AI researchers burning through that compute, so you see exactly what your infrastructure unlocks. Python and Linux.
If you've wanted to point your platform engineering skills at something that actually matters, clean, abundant energy, this is about as direct a shot as it gets, and it's happening in Europe.
Interview process: recruiter call, meet the team lead, technical panel, meet the CEO.

Tahoma builds AI agents that automate healthcare Revenue Cycle Management (RCM): eligibility, claim status, claim submission, denials, and payment posting. We're live in production with paying enterprise customers.
Our agents operate payer portals behind MFA, green-screen terminals over SSH, and Windows desktop software, where some actions are irreversible. They run on a deterministic orchestration layer we built in-house, with model calls as bounded steps, not the control loop.
Stack: TypeScript/Node.js, Playwright, computer-use agents, Claude, Postgres, Azure, K8s.
You'll get to own the core platform end to end and make the real architecture calls: resilience to portal changes, exactly-once guarantees, observability, and cost per run.
Team: Founder from AWS, the former UnitedHealthcare CIO, advisors from Microsoft Research and Shopify's AI team, and a remote engineering team in-flight.
Please write us at careers@tahoma.io with your resume and one thing you've shipped. You can see more at https://www.tahoma.io/careers

We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.
We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.
You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.
This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.
We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!
Hiya makes phone calls trustworthy again. We do caller ID, spam and scam protection, and branded calling for carriers, phone makers, and businesses.
I run the Communications Platform team (Seattle + Barcelona). We're building new systems where telephony meets AI: real-time scam detection on live calls, deepfake voice detection, speaker verification, and AI call screening that plugs into carrier networks. Most of it is new work, so you'll help make early architecture decisions.
Stack: TypeScript/Node.js, SIP/RTP, STT/TTS, Docker, Kubernetes, AWS, Terraform, Helm.
Looking for 3+ years of backend experience, strong TypeScript or Python, and comfort with APIs and event-driven systems. VoIP/telephony experience is a big plus but not required. I came to telecom from a software background too.
Apply: https://jobs.ashbyhq.com/hiya/2de4d41b-a919-48c4-9a6c-e0d4f3...

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.
There are a lot of companies in the auth space, but we feel like we have something special:
* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

We’re building the inference platform for visual intelligence. We’re a deeply technical team of AI / computer-vision engineers (20+ years combined, MIT/CMU/NC State PhDs) who’ve shipped production ML infra across autonomous driving and LLMs.
We launched the VLM Run Gateway (https://vlm.run/gateway) in September, a unified API that serves open-weight VLMs, embodied VLAs, ViTs, served across a fleet of GPUs and clouds. That's exactly the infrastructure problem this role will own. We're already scaling to serve 100s of thousands of requests per day, so if this sounds exciting to you, read on.
Email us at hiring@vlm.run with your GitHub profile, papers, ML projects you’ve recently shipped (100+ GH stars only) - especially with Ray, k8s, GPUs, serverless. No AI text please, keep it short, shorter emails are more likely to get a response. No remote work, must be in the Bay Area (specify in email subject).
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.

If you want to build fast with high autonomy and believe in strong typing as much as we do, we'd love to hear from you!
We're building the VMware for GPUs. Most GPUs in the cloud sit idle a lot of the time because they're bolted to one machine over PCIe. We decouple them.
Our virtualization layer is a userspace shim, loaded through LD_PRELOAD, that intercepts CUDA calls and ships them over the network to a host with a physical GPU somewhere else in the data center. Workloads run unchanged. When a process goes idle, the GPU detaches and gets reassigned, and reattaches in tens of milliseconds when it's needed again. Think Ceph for GPUs: the GPU becomes a network resource a cluster-wide scheduler can pool and pack.
The hard part is making that fast. We're within ~10% of native on most AI workloads, and it lets us serve ~1.8x more users on the same fleet. We run it in production as our own GPU cloud and sell it to enterprises with underutilized fleets.
Team is from Citadel Securities, Aquatic, Old Mission, AWS, and Bain. Series A, $17.5M raised from Matrix and Y Combinator.
Open roles:
- Software Engineer, C++ Systems ($215K-$325K + meaningful equity). Low-level, latency-sensitive work on the virtualization layer. Quant dev / HFT background preferred: https://jobs.ashbyhq.com/thundercompute/2efae53b-817c-43e7-9...
