Senior Software Engineer - AI Agent Evaluation at Mindrift. Location Information: Anywhere in the World. . . Headquarters:. Canada . URL:. . https://mindrift.ai/. . . 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.. . . 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. . . 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.. . . How it works. . Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid. . . 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.. .
