Senior Python Engineer - AI Coding Agent Evaluation (Freelance)

Mindrift Connects Specialists with Project‑Based AI Opportunities 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.

What this opportunity involves We're building a dataset to evaluate AI coding agents – how well a model handles real‑world developer tasks.

Responsibilities

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 this is NOT

Not data labeling

Not prompt engineering

Not writing code from scratch – the agent writes most of the code; you guide and evaluate

Qualifications

8+ years in software development

Core stack: Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, Redis

Experience writing tests (functional, integration)

English proficiency – B2+

Challenges Frontier models are already good at coding. Creating a task that genuinely challenges the best models is non‑trivial. You need to 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.
