About the role
- Enterprise agents are complex systems, and they only pay off when their work is reliable and economically viable.
- Evaluation is how you get both: checking correctness is the obvious case, and routing is the subtler one, since choosing a model against cost, latency, and quality requires quality to be measurable at all.
- Knowing where the bar sits is the hard part.
Responsibilities
- Build verifiers over agent trajectories and outputs, calibrated and hard to game.
- Build the eval platform that runs offline environments, task suites, and grading at scale.
- Own the rollout gates that decide whether an agent change ships.
Requirements
- Professional, academic, or research experience in agent engineering and evaluation, including how agent runtimes and harnesses produce a trajectory and where it fails.
- Bachelor's Degree in Computer Science or a related technical degree such as Electrical Engineering, Physics, Mathematics, Computer Engineering, Information Systems or Statistics
- 1-5 years in industry level software engineering
Nice to have
- Strong software engineering fundamentals, and the ability to work independently on ambiguous, loosely specified problems.
Benefits

- $1.5K monthly stipend for meals
- Generous equity grant vested over 4 years
