About the RoleThis is a hands-on, end-to-end ownership role on a small, high-caliber engineering team building infrastructure for AI evaluation and reinforcement learning environments. You'll be the person who unblocks critical deployments for frontier AI labs and data vendors - diagnosing ambiguous problems fast, shipping solutions, and turning repeated firefighting into durable tooling. The work is urgent, impactful, and rarely fully prescribed.
What You'll Do- Take the lead on diagnosing and resolving ambiguous technical problems as they arise.
- Own technical deployment requests from frontier AI labs and data vendors, from initial triage through to completion.
- Ask the right questions to clarify underspecified asks and identify what actually needs to be built.
- Build one-off tools and pipelines to solve urgent customer or partner problems quickly.
- Coordinate with research and go-to-market teams to keep deployments moving.
- Balance speed and quality under time pressure when the path forward isn't fully defined.
- Document recurring issues and convert repeated manual work into reusable tools and processes.
What We're Looking For- 2-4 years of experience in applied research engineering, forward-deployed engineering, or a closely related hands-on technical role.
- Proficiency in Python, Docker, and Linux environments.
- Experience working on benchmarks and evals - with solid judgment about task realism, rubric reliability, and trajectory quality for RL training.
- Strong debugging instincts across code, data, and environments.
- Proven ability to operate independently in ambiguous situations without a fully prescribed roadmap.
- Comfort working directly with technical customers, vendors, and cross-functional internal teams.
- Experience handling urgent production, customer, or deployment issues under pressure.
- Early-stage startup experience and the ability to move fast in a small, high-ownership environment.
- Strong written and verbal communication skills for async, cross-timezone collaboration.
