• Help define and evolve best practices, patterns, and architecture

• Demonstrated ability to use AI to increase speed, improve code quality, and reduce rework
• Strong judgment on when to trust vs. verify AI‑generated code
• Strong understanding of testing (unit/integration), CI/CD, and code quality practices
• Experience working in fast‑paced, ambiguous environments
• Proven ability to scope, break down, and deliver complex features
• Skilled at working and communicating cross‑functionally with Product, Design, and other SME's and explaining technical decisions clearly
