• Active daily use of LLM-powered coding tools (Claude Code, Codex, GitHub Copilot, or similar) to write and ship code
• Experience building and consuming APIs, handling system integrations, and working through the full development lifecycle
• Comfortable working in fast-paced environments where priorities shift and you need to figure things out
