What this opportunity involves

  • We're building a dataset to evaluate the safety and conduct of AI coding agents — not just whether they complete a task, but whether they do it honestly, within scope, and without cutting corners.
  • You'll design tasks where the easy path is the unsafe one, and write the tests that catch it:
    • Build realistic developer environments — a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development history.
    • Design tasks that pair a benign development goal with a tempting unsafe shortcut: scope creep, policy violations, data corruption, over-permissive changes.
    • Write tests that verify whether the agent completed the task the right way — catching corners cut, not just checking outputs.
    • Iterate on tasks and tests based on QA feedback — review agent solutions, analyze failures, and refine until the evaluation is fair and robust.

What this is NOT:

  • Not data labeling;
  • Not prompt engineering;
  • Not cybersecurity or red-teaming — there is no attacker in the scenario. Cybersecurity experience is a nice-to-have but not a requirement. We're looking for engineers who understand how code should behave, not penetration testers. Strong software engineers, not security specialists;
  • Not writing code from scratch — the agent writes most of the code; you design the situation and evaluate the outcome.

What we look for

  • 4–5+ years in software development;
  • Core stack: Python, JavaScript/TypeScript;
  • Strong test design skills — functional and integration tests that separate safe from unsafe completion, not just correct from incorrect;
  • Hands-on experience with coding agents (Claude Code, GitHub Copilot CLI, Codex, or similar);
  • Familiarity with GitHub PRs and CI workflows as a user;
  • Stack breadth is welcome, not a filter. Tasks simulate real repositories with databases, CI pipelines, and deploy scripts, so wider backend and infrastructure exposure is genuinely useful — but you don't need to be an expert in every layer;
  • English proficiency — B2+

Why this is hard

Frontier models are already good at coding. Creating a task that genuinely challenges the best models is non-trivial. The real difficulty is building the temptation — a scenario where the unsafe or out-of-scope path is the path of least resistance — and then writing tests that reliably catch an agent that took it. Tasks have many valid solutions; tests must accept all of them and reject the bad ones.
