  • Strong programming skills and CS fundamentals, with mastery in at least one backend language (Java, Python, etc.) and modern frontend frameworks (React, Angular, TypeScript).
  • Proven experience designing and evolving large-scale distributed systems and microservice architectures.
  • Demonstrated ability to own technical domains, making architectural trade-offs and long-term design decisions.
  • Experience driving cross-domain initiatives, coordinating with multiple teams to deliver cohesive solutions.
  • Track record of mentoring engineers, leading technical discussions, and influencing outcomes at an organizational level.
