Software Engineering Evaluation Specialist

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-root user
• Linux & Bash comfort debugging inside containers (strace, lsof, journalctl); shell beyond set -euo pipefail
• AI coding agent experience Claude Code, Cursor, Roo Code, or similar, on non-trivial work
• You can cite a specific time the AI was confidently wrong and how you caught it
• English B2+ written
• Not a fit Data Science, ML, or Computer Vision engineers without backend-engineering output
• Manual QA testers without automation or test authoring
• Frontend-only, low-code / no-code, IT Support, or Business Analysts
• Engineers who have never written pytest from scratch
• Junior, intern, or assistant as the most recent role
• Preferred qualifications Domain depth in Security, System Administration (nginx / systemd / cron), Scientific Computing (NumPy / PyTorch / SciPy), DevOps, or Git internals
• Modern Python tooling (uv, poetry, pyproject.toml)
• Coverage tooling (pytest-cov, coverage.py, gcov, llvm-cov, kcov)
• Fuzzing or property-based testing (Hypothesis)
• Prior contribution to agent-evaluation benchmarks or related frameworks
• Desired Candidate Profile 3+ years of production software development in one backend stack Python, Go, Node.js, Java, or Rust
