Freelance Optical Engineer with Python Expertise

Please submit your CV in English and specify your English proficiency level. Mindrift connects skilled professionals with contract-based AI projects from leading technology companies. This freelance role centers on evaluating, testing, and refining AI systems. It is a contract position only, not a path to permanent employment. Role overview This project focuses on building a dataset to assess how well AI coding agents perform real-world software development tasks. The work requires designing realistic challenges and evaluation methods within simulated developer environments. Key responsibilities Create virtual companies from high-level plans, building out codebases, infrastructure, and context such as conversations, documentation, and tickets to simulate authentic development histories. Develop and refine tasks for different stages of the virtual company, including writing prompts, setting evaluation criteria, and ensuring tasks are solvable and fairly assessed. Design assignments in isolated environments that closely resemble a developer’s workstation, including a Linux machine with development tools (terminal, CLI), MCP servers (repository, task tracker, messenger, documentation), and a live web application codebase. Implement tests that accept all correct solutions and reject incorrect ones, carefully balancing strictness and leniency. Collaborate with an AI agent during test runs to confirm that tests catch real issues, flagging faulty solutions without penalizing correct ones. Review code generated by AI agents, analyze reasons for success or failure, and design edge cases and adversarial scenarios to expose weaknesses. Iterate on your work based on feedback from expert QA reviewers who will check your outputs against quality standards. What this role does not involve Data labeling Prompt engineering Writing code from scratch (the AI agent generates most of the code; your focus is on guiding and evaluating) Much of the work involves close collaboration with AI models, as developing challenging tasks for advanced systems requires working directly with them.
