Senior Java Engineer (Backend) - FS Poly with Security Clearance

Senior Java Engineer (Backend)

• FS Poly
• Annapolis Junction, MD Who We Are Stanley Reid is a specialized recruiting firm connecting top contractors with exciting IC/DoD opportunities.

We're dedicated to a personalized, stress-free job search, matching your unique skills and goals with the perfect role. About Our Client Founded by IC/DoD veterans, our Maryland-based client prioritizes high-impact solutions over corporate growth, with work across MD and VA. They maintain a flat, "people-first" culture where senior leaders work alongside engineers to solve complex challenges in Big Data, Analytics, and Cloud Services.

This is not a "cheeks-in-seats" shop; If you aren't enjoying your project or if a contract is affected by funding, they are primed to pivot you to a better-aligning role. This commitment to long-term fit has resulted in a zero-layoff history since 2013. Along with strong salaries, they offer a comprehensive benefits package including full family medical coverage, immediate 401k vesting, 30+ days of PTO, and generous tuition reimbursement. The Role 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.

What You'll Bring 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.
