• We are looking for awareness of AI coding assistants such as GitHub Copilot, Cursor, or Claude to accelerate development, generate boilerplate, and review code.
• We expect the ability to apply AI tooling critically by validating, refactoring, and integrating AI-generated code rather than accepting output uncritically.
• We value awareness of prompt engineering techniques relevant to software development workflows, including code generation, test writing, documentation, and debugging.
• We require experience working in an Agile/Scrum environment.
