Member of Technical Staff - Platform

We are looking for a generalist software engineer with 2–6 years of experience to join our platform team and help build the infrastructure that powers LLM evaluations at scale. You'll work across the stack – from Python backend services to React frontend features – shipping quickly in a high-autonomy environment. This is a pure IC role where you'll be hands-on every day, tackling open-ended problems and iterating fast. We want someone with a sign of excellence – whether that's an impressive company, interesting research, a top-tier school, or a compelling project.

What you will be doing

- Building and maintaining the platform that runs LLM benchmarks end to end – Python libraries, web platform, cloud infrastructure, and tooling

- Working across the full stack as a generalist – backend Python/Django services and frontend React/TypeScript features depending on team needs

- Taking fuzzy, open-ended problems and independently designing, building, and shipping solutions

- Performing code reviews and architecture reviews for other engineers on the team

- Collaborating closely with the research team to ensure infrastructure meets their evaluation needs
