Strong understanding of system design, scalability, and performance
Bonus points:
Experience working with coding agents (Cursor, Claude Code, Codex, or similar) is a strong plus
Experience deploying and operating services on AWS (or another major cloud provider) is a strong plus.
Experience building or integrating AI agent systems (LLM workflows, tool-use, orchestration frameworks, or evaluation pipelines) is a plus
