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'll 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:
Not data labeling
Not prompt engineering
Not 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), Java

Script/Type

Script (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.
