Mindrift: Senior Software Engineer - AI Agent Evaluation
Headquarters: Canada

Please submit your CV in English and indicate your level of English proficiency.
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.
About the Role
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.
Responsibilities
- Build realistic developer environments: Create a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development history.
- Design tasks: Create 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: Verify agent solutions by creating tests that accept all valid approaches and reject incorrect ones, ensuring they are neither too strict nor too lenient.
- Iterate: Refine tasks and tests based on QA feedback, review agent solutions, analyze failures, and improve 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)
Requirements
- 5+ 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 20 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 $50/hr equivalent, depending on level and pace. Tasks are estimated at ~20 hours each; you set your own schedule.
