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.

You will 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 this is NOT • Data labeling. • Prompt engineering. • Writing code from scratch - the agent writes most of the code; you guide and evaluate.

What we look for • 8+ years in software development. • Core stack: Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, Redis. • Experience writing tests (functional, integration). • 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. 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.
