Role Overview As a Freelance AI Agent Evaluation Engineer, you will help build a dataset that measures how well AI coding agents perform real-world software development tasks. The work centers on designing complex tasks and evaluation criteria within detailed simulated environments. What You Will Do Create virtual companies from high-level blueprints, including codebases, infrastructure, and realistic context (conversations, documentation, tickets) to simulate authentic development environments with history. Curate and adjust tasks at various stages of the virtual company. This includes developing prompts, defining evaluation criteria, and ensuring tasks are solvable and fairly assessed. Design challenges in isolated settings that mimic a developer's workstation: a Linux environment with development tools (terminal, CLI), MCP servers (repository, task tracker, messenger, documentation), and a real web application codebase. Develop tests that reliably accept all correct solutions and reject incorrect ones, aiming for a balance between strictness and fairness. Work alongside an AI agent on these tests, making sure the agent catches real issues, does not accept poor solutions, and passes valid ones. Review code generated by AI agents, analyze both successes and failures, and design edge cases and adversarial scenarios to further challenge the models. Iterate on your approach based on feedback from expert QA reviewers who assess your work for quality. What This Role Does Not Include Data labeling Prompt engineering Writing code from scratch (the AI agent will handle most coding; your focus is on guiding and evaluating) Much of the work involves close collaboration with advanced AI models, crafting tasks that push their capabilities.
