SENIORITY
Lead
About the role
About Hillclimb Hillclimb’s mission is to improve agent capabilities towards recursive self-improvement. To do so, we work on creating environments and evals that test and push frontier models’ ability to ideate, experiment, and produce impactful research.
We’re a founding team of former DeepMind & quant researchers, backed by Tier 1 VCs, Jeff Dean, Paul Graham, Amjad Masad, and angel investors from OpenAI, Anthropic, DeepMind, xAI & Meta Superintelligence Labs.
About this role:
Your work will consist of the following and many more:
Turn ML research problems into environments that reward a model for real progress and good research taste Test whether each environment’s reward is repeatable and tracks the quality of the work it scores Build systems that create environments at scale and catch broken ones before they reach training Run post-training experiments to find which environments are trainable
Preferred Experience:
- Prior experience with LLMs, RL, RLHF/RLAIF, RLVR, post-training, evals, graders, synthetic data, model training, or coding agents at a frontier/data lab
- Understanding of what makes a reward evaluation trustworthy, and how models exploit one that is not
- Background in designing automated systems for building, validating, and quality checking environments.
Benefits:
- Health, dental, vision insurance
- Competitive 401k match
- Free lunch & dinner
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
