Job description

SR JAVA FULL STACK DEVELOPER (AWS / EKS / Angular)

Location: Hybrid — Reston, VA (20190) (90% remote - 4 to 6 onsite meetings a year) Type: Contract Schedule: 40 hours/week Pay (W2): USD $97.00/hr

JOB OVERVIEW

We’re seeking a Senior Java Full Stack Developer to a strategic cloud modernization initiative (deliverables targeted through the end of 2026). This role is focused on replatforming/migrating existing services - moving Java REST services currently deployed on-prem into AWS (EKS) - while continuing to support a modern Angular front end.

This is a backend-leaning full stack role (70% backend / 30% frontend). Pure backend candidates won’t be a fit: the team needs engineers who can flex across the stack as priorities shift and who can demonstrate real front-end experience plus strong aptitude.

WHAT YOU’LL DO

  • Perform hands-on design, coding, testing, and support of complex enterprise applications at scale
  • Help migrate and modernize Java REST services from on-prem to AWS EKS
  • Build and maintain Java web services and integration layers between UI and data sources
  • Contribute to the Angular front end as needed (this is not a UI-only role, but UI contribution is required)
  • Work with databases including MongoDB and Aurora PostgreSQL (similar enterprise DB experience is acceptable)
  • Implement and execute automated testing and quality practices (including Playwright)
  • Support CI/CD, code quality, and DevOps-aligned delivery standards
  • Provide production support, troubleshoot critical issues, and drive continuous improvement
  • Participate in scoping/architecture conversations and mentor junior engineers as needed

REQUIRED QUALIFICATIONS

  • Bachelor’s degree in IT/Computer Science (or additional relevant experience in lieu of degree)
  • 5+ years of software engineering experience across the SDLC (requirements, design, build, test, and support)
  • Full stack experience with a backend-heavy focus (70/30 backend/frontend)
  • Java 17+ required (environment currently using Java 21)
  • Angular 17+ required (currently on Angular 18, targeting newer versions)
  • AWS is a hard requirement, including multiple years deploying and managing EKS
  • Experience migrating/replatforming services from on-prem to AWS
  • Strong experience with modern engineering practices: CI/CD, automated testing, agile delivery, and code quality standards

NICE TO HAVE

  • AWS certifications (especially AWS Developer or AWS Solutions Architect) — “highly preferable”
  • Experience with AWS AI/coding assistants (e.g., Amazon Q, Kiro) and an AI-first engineering mindset
