Extensively leverage GitHub Copilot and/or Claude Code in VS Code for development, refactoring, debugging, and test generation.
Implement UI, business logic, and integrations; ensure functional completeness through unit and regression testing.
Independently troubleshoot issues, resolve defects, and support deployment.

Required Skills & Candidate Profile

Programming: Strong OOP, SOLID principles, design patterns, and clean coding practices. C#/.NET preferred, strong Java developers acceptable.
AI & Tools: Demonstrated hands-on expertise with GitHub Copilot and/or Claude Code, Visual Studio Code, Git/GitHub.
Engineering: Legacy modernization, application development, debugging, automated testing, and REST APIs.
Preferred: .NET 10, ASP.NET Core, Docker, Kubernetes, OpenShift ROSA, CI/CD.
Core Attributes: Exceptional problem-solving, critical thinking, adaptability, independent execution, and ownership of code quality.

Selection Priority: Proven AI-assisted development proficiency, strong OOP fundamentals, and independent problem-solving. Hands-on developers required.
