• Expert-level Docker skills (reproducible Dockerfiles, user contexts, secure workspaces)
• Strong Linux & Bash scripting skills and comfort debugging inside containers
• Proficiency with modern Python tooling (uv, pyproject.toml, packaging)
• Ability to read and understand with LLM many coding languages (for example C, C++, Rust, or Go)
• Experience using LLMs (Claude Code, Roo Code, Cursor) to accelerate iterative development and test-case generation
• English language - B2 or higher

Additional Requirements

• Prior experience with agent evaluation platforms and MCP CLI
