Freelance Agent Evaluation Engineer - AI Projects on Mindrift
Mindrift
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 virtual companies following a high-level plan - codebase, infrastructure, and context (conversations, documentation, tickets) that form a realistic environment with development history - Assemble and calibrate tasks from intermediate states of the virtual company: craft the prompt, define evaluation criteria, and ensure the task is solvable and the evaluation is fair - Design tasks set in isolated environments - emulations of a developer's workstation: a Linux machine with development tools (terminal, CLI), MCP servers (repository, task tracker, messenger, documentation, etc.), and a real web application codebase - Write tests that accept all correct solutions and reject incorrect ones - neither too strict (breaking on valid approaches) nor too lenient (passing bad ones) - Iterate with an AI agent on tests - verifying they catch real problems, don't miss bad solutions, and don't break on good ones - Review code written by agents, analyze why an agent failed or succeeded, and design edge cases and adversarial scenarios - Iterate based on feedback from expert QA reviewers who score your work on quality criteria 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 A significant part of the work is done together with AI - it's very hard to create tasks that challenge frontier models without using frontier models. What we look for This opportunity is a good fit for experienced developers, software engineers, and/or test automation specialists open to part-time, non-permanent projects. Ideally, contributors will have: - Degree in Computer Science, Software Engineering, or related fields - 5+ years in software development, primarily Python (FastAPI, pytest, async/await, subprocess, file operations) - Background in full-stack development, with experience building React-based interfaces (JavaScript/TypeScript) and robust back-end systems - Experience writing tests (functional, integration — not just running them) - Docker containers, and familiarity with infrastructure tools (Postgres, Kafka, Redis) - CI/CD understanding (GitHub Actions as a user: triggers, labels, reading results) - English proficiency - B2 You don't need to be an expert in every item, but you should be comfortable reading and reasoning about code across the stack. 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 On this project, contributors can earn up to $50 per hour equivalent, depending on their level and pace of contribution. Compensation varies across projects depending on scope, complexity, and required expertise. Please note that other projects on the platform may offer different earning levels based on their requirements.
