Software Engineer – AI Evaluation / Coding Agents

About the Role
We're looking for experienced, hands-on software engineers to help evaluate and improve AI coding models.

Rather than primarily building production applications, you'll work with coding agents across real-world repositories and assess the quality of their work — reviewing generated code and agent behavior, determining whether solutions are technically correct, identifying failure modes, and creating the evaluation signals and feedback used to improve model performance.

Think of the coding agent as another engineer whose work you're reviewing: Can it understand the task? Did it choose the right approach? Is the resulting code correct, robust, and maintainable? Can you explain precisely where it succeeded or failed?

What You'll Do

Design, refine, and iterate on rubrics and evaluation criteria for preference data

Review and label data with a high quality bar, catching subtle issues others might overlook

Build and maintain pipelines and infrastructure supporting data generation, collection, and evaluation workflows

Synthesize findings from data work into clear write-ups, updates, and recommendations for the team

Collaborate closely with researchers and engineers to translate qualitative judgment into scalable processes

What We're Looking For

5+ years of hands-on software engineering experience

Strong proficiency in Python, TypeScript/JavaScript, Go, or another major production language

Experience working in substantial real-world codebases

Strong code-review skills and technical judgment

Ability to clearly explain why an implementation is correct, incorrect, or could be improved

Strong written communication

Experience using modern LLMs or AI coding tools

Nice to Have

Experience with LLM evaluation, coding agents, RLHF, preference data, rubric design, or post-training
