Senior Java Engineer (Backend) - FS Poly

Our client is seeking a Senior Java Engineer in Annapolis Junction to join a team focused on building scalable, mission-critical backend systems. This isn’t a “frameworks-for-the-sake-of-frameworks” environment; we’re looking for someone with a thoughtful engineering mindset who knows when to use Spring and Hibernate and when to opt for lightweight, pragmatic alternatives. Key responsibilities include designing RESTful APIs, managing data access layers (Relational and NoSQL), and owning complex technical problems from design through production in a Linux/RHEL environment. This role is perfect for a developer who prioritizes clean code, system performance, and long-term maintainability over one-size-fits-all patterns. Salaries range from $170k - $260k+, commensurate with experience and LCATs.

Experience: BS and 7-20+ years of professional backend Java development. Years of experience can replace degrees.

Technical Depth: Strong proficiency in core JVM concepts, Spring, and Hibernate.

Systems & Data: Experience building RESTful APIs, solid understanding of relational databases/schema design, and familiarity with Linux/Unix (RHEL) environments.

Engineering Best Practices: Proven ability in system design, clean code, version control (Git), and Agile methodologies.

Bonus Skills: Experience with NoSQL (MongoDB, Elasticsearch), CI/CD toolsuites (GitLab/Atlassian), or frontend exposure (React/Angular).

Clearance Requirements

TS/SCI with FS Polygraph is required. We are not able to upgrade clearances or accept CCAs. Please note, you must have the required clearance for consideration; under-cleared applicants will not receive a response.
