About Positron AI Positron AI is building next-generation AI inference accelerators designed from the ground up for low-latency, high-throughput large language model inference. Backed by NEA.
About the role
The Accelerator Platform Software (APS) team owns the software closest to the metal: the host-side platform layer, the device-side runtime and firmware, the Linux-based device OS, the simulation and emulation environments we use to build software ahead of silicon, performance and debug tooling, and product security. If it touches the accelerator, it goes through us. We build with AI-native workflows, where agentic coding tools, a shared skills repository, and automation are core to how the team ships.
What they're looking for
- A strong software engineering background, with systems or infrastructure experience strongly preferred, this is an engineering role, not a prompt-writing role
- Hands-on, expert experience using agentic development tools such as OpenAI Codex and Claude Code, integrating LLM APIs, and building evaluations
- A shipped track record of internal tooling or developer-productivity work that engineers actually adopted
- The credibility and patience to win over skeptical senior systems engineers with results rather than demos
- Self-directed working style, comfortable defining your own roadmap from observed friction without a team around you
- Excellent written communication skills, since we run on written plans, design docs, and async updates

This role sits on the Director's staff and owns making that leverage real across every sub-team. Most companies would staff an entire developer-systems team for this mission. We are hiring one person and giving them the whole thing. You will be the engineer who makes AI-assisted development actually work in a shop where the code talks to registers and a wrong answer means a hung device, not a bad paragraph. You will embed with each sub-team, find where their week goes, and build agentic workflows that give it back, then prove the gains with evaluations rather than enthusiasm. You report directly to the Director of APS, and your roadmap is yours to define from the friction you...
