What you'll do
- Create challenging tasks and evaluation criteria within realistic simulated environments
- Build realistic developer environments - a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development history
- Design tasks from intermediate states of these environments - craft the prompt, define what "solved" means, and ensure the task is solvable by an AI agent
- Write tests that verify agent solutions - accept all valid approaches and reject incorrect ones, neither too strict nor too lenient
- Iterate on tasks and tests based on QA feedback - review agent solutions, analyze failures, and refine until the evaluation is fair and robust
What they require
- 8+ years in software development
- Experience writing tests (functional, integration)
- English proficiency - B2+
- Deeply understand where models fail and what scenarios reveal the difference between a good and a bad solution.
- Tasks have many valid solutions - writing tests that accept all correct solutions and reject incorrect ones is harder than it sounds.
