We are looking for a strong Java Backend Engineer who can build and operate WhiteCoat’s backend services in a Codex-first, AI-native engineering environment.

• Summon and coordinate multi-agent workflows for backend design review, API analysis, database investigation, production issue diagnosis, and release review.

• Design MCP/tool access with clear permissioning, audit logs, least-privilege access, PII controls, and failure handling.

• Support production issue investigation using logs, metrics, traces, database checks, monitoring tools, and release evidence.
