Requirements

• You hold a Bachelor's or Master's Degree in Software Development, Computer Science, or other related fields
• You have at least 3 years of professional experience with excellent command of Ruby and key ecosystem tools (RSpec, Bundler)
• Your level of English is advanced (C1) or above
• Confident use of Git and standard Linux CLI tools
• Hands‑on experience with containerization (Docker) and CI/CD pipelines (e.g., GitHub Actions, GitLab CI, Jenkins)
• Deep understanding of testing principles and test‑driven development (TDD); strong skills in debugging, profiling, and code optimization.

Desirable

• Contributions to open‑source Ruby projects (pull requests, code reviews, issue tracking)
• Experience working with large monorepositories or major open‑source projects
• Experience with automated benchmarking, scripting, or infrastructure‑as‑code tools
• Experience working with AI‑generated code or in code evaluation projects

Soft Skills

• Analytical and detail‑oriented mindset: proactively identifies bugs, edge cases, and test coverage gaps
• Concise and structured communication, both in documentation and asynchronous team discussions
• Strong ownership: able to drive tasks end‑to‑end, propose improvements, and promptly flag risks or blockers
• Adaptability and resilience: thrives in fast‑changing requirements and ambiguous project contexts
• Team player: open to code reviews, feedback, and knowledge sharing
• You are ready to learn new methods, able to switch between tasks and topics quickly and sometimes work with challenging, complex guidelines

Our freelance role is fully remote so, you just need a laptop, internet connection, time available and enthusiasm to take on a challenge.
