Type: Contract
Schedule: 40 hours/week
Pay (W2): USD $97.00/hr

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.

• 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

• 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

• 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
