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.

This person should have solid backend fundamentals and be able to build MCPs, API connectors, and agent-accessible tooling that allow AI agents to support requirements analysis, development, testing, monitoring, and incident investigation safely.

• Build reliable, secure, maintainable backend features supporting mobile, Doctor Portal, CMS, operations, payment, claims, medication, and partner workflows.

• Use Codex and AI coding agents to accelerate development, refactoring, test generation, documentation, bug investigation, and release preparation.

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

• Build MCP servers, internal API connectors, and tool adapters that allow AI agents to safely access approved systems such as Jira, logs, monitoring data, documentation, runbooks, GitHub, databases, and operational tools.

• 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.

• Improve backend reliability, performance, observability, error handling, deployment safety, and operational supportability.

• Work with Product, QA, Mobile, DevOps, Data, IS, and Support to diagnose and resolve issues quickly.
