Freelance Agent Evaluation Engineer

Job Description Roles & Responsibilities 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. 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. Desired Candidate Profile 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.
