  • Build reusable components and shared libraries to support long-term platform evolution
  • Participate in technical discussions, design reviews, and code reviews
  • Identify performance, scalability, and reliability challenges and lead their resolution
  • Contribute to engineering standards, best practices, and guidelines
  • Support and mentor other engineers through knowledge sharing and technical feedback
