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.We're building a dataset to evaluate AI coding agents - how well a model handles real-world developer tasks.

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

Not data labeling
Not prompt engineering
Not writing code from scratch - the agent writes most of the code; 8+ years in software development
~ Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, Redis
~ Experience writing tests (functional, integration)
~ English proficiency - B2+

Frontier models are already good at coding. Tasks have many valid solutions - writing tests that accept all correct solutions and reject incorrect ones is harder than it sounds.
