- Deep understanding of modern distributed systems and ability to troubleshoot across the full stack (HTTP/HTTPS, WebSockets, TLS, TCP/IP, DNS)
- Strong understanding of security best practices for exposed APIs and backend services: authentication, authorization, data isolation, encryption, and audit logging
- Strong problem-solving skills with the ability to take full ownership of projects-from design through deployment, maintenance, and iteration
- Excellent written and verbal communication skills; a collaborative team player who seeks feedback and drives continual improvement
- Demonstrated use of AI coding agents and tools (e.g., GitHub Copilot, Cursor, Claude Code, or equivalent) to meaningfully improve personal and team productivity - treating AI-assisted development as a standard part of the modern engineering workflow
