Job summary

Mindrift is building a dataset to evaluate AI coding agents by creating realistic developer environments—tickets, docs, and a believable history of code changes. You’ll design tasks from intermediate states, craft prompts, and define what counts as a solved task, ensuring tests accept all valid approaches and reject incorrect ones.

This project-based role requires 8+ years in software development and English proficiency (B2+).

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+.

Responsibilities

• Design evaluation tasks and tests for AI coding agents.
• Build realistic developer environments with codebases, infra, tickets and docs.
• Write tests that accept multiple valid solutions and reject incorrect ones.
• Iterate on tasks based on QA feedback to improve fairness and robustness.

Job description

Industry Information Technology Enabled Services (ITES)

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), 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.

Effort estimate:

Tasks for this project are estimated to take 30 hours to complete, depending on complexity. This is an estimate and not a schedule requirement; you choose when and how to work. Tasks must be submitted by the deadline and meet the listed acceptance criteria to be accepted.

Compensation:

Up to $200/hr equivalent, depending on level and pace. Tasks are estimated at approximately 30 hours each; you set your own schedule.
