• Deep understanding of backend architecture, distributed systems, databases, caching, and performance optimization
• Experience evolving complex production systems, including executing migrations and making architectural changes without compromising reliability or availability
• Experience working in engineering environments where scalability, performance, and reliability are critical, ideally at a growing startup or established technology company
• Strong programming skills and comfort working across backend services and infrastructure
• Strong technical judgment and the ability to navigate complex codebases, design thoughtful abstractions, and evaluate tradeoffs between simplicity, performance, and maintainability
• A builder's mentality, intellectual curiosity, and comfort taking ownership in a fast-moving, entrepreneurial environment
