Troubleshoot production issues across application, database, and integration layers; lead incident response and produce durable fixes.

Contribute to system design decisions including hardware/software trade-offs and reuse vs. new development (COTS/GOTS).

Review code, produce design documentation, and mentor less-experienced engineers.

Proven, hands-on experience developing and maintaining Java/Spring Boot applications: RESTful APIs, microservices, dependency injection, configuration management, and production troubleshooting.

Hands-on experience with NoSQL databases: data modeling, querying, indexing, performance optimization, and integrating NoSQL stores with Spring Boot.

What we'd like you to have

Familiarity with MongoDB: document modeling, queries, indexes, aggregation, and Spring Data MongoDB.

Experience integrating applications with LDAP/Active Directory, including user authentication, authorization, directory lookups, and Spring Security/LDAP.

Strong understanding of REST APIs, distributed systems, application security patterns, and enterprise application architecture.

Experience with automated testing, CI/CD pipelines, Git, Maven, and production deployment environments.

Ability to troubleshoot complex application, database, and integration issues; proven collaborator across development and infrastructure teams.
