Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.
About the Role
You’ll design coding tasks that challenge frontier AI coding agents. Each task is a self-contained Docker environment with a broken piece of software; an AI agent attempts the fix; automated tests verify the outcome. Your deliverable is the full task package: broken code, tests, instructions, and a reference solution proving the task is solvable.
Responsibilities:
Invent a realistic developer scenario — a real bug, a broken ETL, a missing feature — not a toy problem.
Build a reproducible Docker environment with pinned dependencies.
Write a pytest that verifies outcomes, not specific commands — deterministic, non-flaky, and does not leak the fix.
Write an instruction.md that reads like a Jira ticket a developer would receive.
Write a reference solve.sh proving the task is solvable.




Calibrate difficulty so current state-of-the-art agents solve the task 20–60% of the time.
Iterate based on feedback from expert QA reviewers.
Later: review other authors’ tasks as a QA reviewer.
Not in scope
Data labeling, prompt engineering.
Production code to ship — you design problems and verification for AI agents.
Leetcode puzzles — scenarios must look like real developer work.
Not every candidate task ships — quality over quantity.
Requirements
3+ years of production software development in one backend stack — Python, Go, Node.js, Java, or Rust. Depth in one stack beats breadth.
Python + pytest fluency — required regardless of primary stack. The task harness is pytest-based even when the broken app is in another language. Fixtures, parametrize, monkeypatch, timeouts, conftest.py.
Docker authoring — reproducible Dockerfiles, pinned dependencies, multi-stage builds when needed, non-ro
