Member of Technical Staff — Research Engineering, Evaluation

We look for research engineers who are excited to tackle unsolved problems. Progress is only as trustworthy as its measurement. As our model, data, and reasoning efforts multiply, every team needs to know, precisely and comparably, whether a change made the model better. Your mission is to build the central evaluation framework that the entire research organization runs on: the pipelines, the metrics, and the tools that turn results into shared understanding.

Responsibilities

- Design and build a central, reusable evaluation framework that every model and every team runs through

- Implement evaluation pipelines, benchmark suites, and baselines that make model quality measurable and comparable across efforts

- Build the visualization and dashboard tools that turn raw results into shared, actionable understanding for the whole team

- Establish sound statistical methodology for evaluation, so teams can distinguish real improvements from noise

- Partner with research and domain teams to translate what "good" means in each domain into standardized, automated metrics

What we're looking for

We value a relentless approach to problem-solving, rapid execution, and the ability to quickly learn in unfamiliar domains.

- Strong software engineering skills and experience building data or evaluation pipelines at scale

- Experience turning research or model outputs into metrics, benchmarks, and visualizations that teams rely on

- Solid grasp of probability and statistics, with the judgment to design evaluations that measure what they claim to

- Full-stack range: comfortable building both backend pipelines and the frontend tools people read results in

- Owns deliverables end-to-end, from collecting requirements to autonomously driving execution
