  • Write clean, testable, and maintainable code with proper documentation.

  • Collaborate with product managers and other teams to understand requirements and deliver customer-focused features.
  • Use AI development tools (required)—including GitHub Copilot, Claude, or similar—to assist with code generation, refactoring, documentation, and development speed.
