About The Position

RIVA Solutions supports the U.S. Patent and Trademark Office (USPTO) by delivering modern, secure, and scalable enterprise software systems that support mission-critical business operations across the patent and trademark lifecycle. RIVA partners closely with USPTO stakeholders to design, build, deploy, and operate complex systems using modern Java/Spring technologies, cloud-native architectures, and DevSecOps practices. Our work emphasizes long-term maintainability, system reliability, security, and operational excellence in highly visible federal environments. RIVA Solutions is seeking a Senior Full Stack Developer who is a hands-on senior engineer, not a purely feature-focused developer. This role requires deep technical expertise, strong system design instincts, and direct ownership of production systems. The ideal candidate has experience building, deploying, and supporting complex applications in live environments and is comfortable being accountable for system behavior after release. This role is well-suited for an engineer who enjoys owning systems end-to-end, including deployment support, troubleshooting production issues, addressing technical debt, and improving operational reliability. This is not a greenfield-only or heads-down coding role. The Senior Full Stack Developer will collaborate closely with product managers, architects, and DevOps teams to bridge legacy systems and modern cloud-based solutions while ensuring code quality, scalability, and system stability.
