Company Overview:

We are building Protege to solve the biggest unmet need in AI — getting access to the right training data. The process today is time intensive, incredibly expensive, and often ends in failure. The Protege platform facilitates the secure, efficient, and privacy-centric exchange of AI training data.

Solving AI’s data problem is a generational opportunity. We’re backed by world-class investors and already powering partnerships with some of the most ambitious teams in AI. The company that succeeds will be one of the largest in AI — and in tech.

We’re a lean, fast-moving, high-trust team of builders who are obsessed with velocity and impact. Our culture is built for people who thrive on ambiguity, own outcomes, and want to shape the future of data and AI.

DataLab is Protege’s research arm — a team of research scientists committed to tackling the fundamental challenges and open questions regarding data for AI. We bridge the gap between research theory and data deployment to push the frontier forward, publishing on the questions that matter: what agentic AI should actually be trained to do, how to quality-control large-scale corpora, and how to build evaluation datasets that reflect the real world rather than the leaderboard.

The Role

Benchmarks decide what AI gets built. Today, most evals don’t measure what we actually care about — they’re contaminated, gameable, synthetic or measure capabilities that don’t transfer to the real tasks frontier models are deployed against. We’re hiring a Research Scientist to lead the design of benchmarks and evaluations that frontier labs, enterprises, and policymakers can actually trust.

You’ll own the science of evaluation across DataLab — designing tasks that meaningfully separate models, validating those tasks against human baselines, and pressure-testing them for contamination, elicitation gaps, and statistical noise. You’ll publish, and your work will directly shape the eval datasets Protege delivers to the most ambitious teams in AI.

What you’ll do

• Design tasks and benchmarks that distinguish capability levels across frontier models — including agentic, reasoning-heavy, and domain-specific (healthcare, finance, scientific) settings.

• Validate evaluations rigorously: run human baselines, analyze inter-rater reliability, study how elicitation and scaffolding shift results, and quantify what’s signal versus noise.

• Develop the “science of evals” at Protege — including item response theory, contamination analysis, predictive validity studies, and statistical frameworks for comparing models with appropriate uncertainty.

• Run evaluations on current frontier models, sometimes in collaboration with partners at AI labs, enterprises, and government.

• Publish research that establishes Protege as the standard-setter for evaluation data, and contribute to the broader AI community’s understanding of what good evals look like.

• Translate findings into product, working closely with the data and engineering teams to turn research into evaluation datasets customers can deploy.

• Partnering with outsourced annotation vendors - Evaluation data is only as good as the people producing it. A meaningful share of this role is owning the statistical machinery that determines which annotators we trust, on which tasks, and by how much — and translating that into trustworthiness scores Protege’s customers can rely on..

What we’re looking for

• Advanced degree (PhD preferred, or MS/BS plus equivalent industry experience) in a quantitative field — applied econometrics with AI experience, quantitative finance, computer science, engineering, statistics/mathematics or any applied research discipline.

• Hands-on experience evaluating LLMs, agents, or other ML systems — including prompting, scaffolding, and fluency with the tooling researchers use to run evals at scale.

• Experience with annotator quality and inter-rater reliability — designing labeling protocols, computing agreement statistics, and reasoning about annotator bias and calibration.

• Excellent scientific writing and communication — you can synthesize technical findings into narratives that frontier labs, enterprise customers, and policymakers can act on.

• A bias toward velocity. You know which pipelines need to be production-grade and which can be scrappy, and you get reliable results fast.

Bonus

• Experience with RL evaluation techniques — reward modeling, off-policy evaluation, evals for RLHF/RLAIF or agentic RL pipelines.

• Ability to navigate new customer architectures, data systems, and requirements quickly.

• Experience with latent-variable models of annotator skill (Dawid-Skene, MACE, IRT-style approaches) or with running large expert-annotator panels in regulated domains.

• Track record of published benchmarks or evaluation papers the field has adopted.
