- Deep hands-on experience designing, building, running, and operating microservices in Kubernetes and cloud environments (GCP, AWS, or Azure)
- Proficiency using AI for coding and research as a daily productivity multiplier (e.g., Claude Code, Copilot, Cursor)
- Strong foundation in distributed systems, API design, data structures, algorithms, and software design
- Thorough testing and code review standards/practices
- Self-starter who identifies problems, proposes solutions, and drives them to completion with minimal direction
