About The Position

Capstone IT is helping our client find a Senior Front-End Developer who will design, build, and maintain enterprise-grade user interfaces for mission-critical applications. This person will own front-end development across the full SDLC — from architecture and component design to testing and deployment. They will work embedded on an Agile team, collaborate closely with back-end engineers, and be expected to produce clean, testable, and performant React code on day one. Within this organization, the Senior Front-End Developer sits on an established software team building and maintaining mission-critical applications — likely internal platforms or customer-facing systems that must perform reliably under real operational load. The role operates across the full SDLC, meaning this person is not handed tickets in isolation; they are expected to contribute to design decisions, set technical standards, and guide quality. The team follows Agile practices, so the developer will work in sprint cycles, participate in planning and retrospectives, and collaborate closely with back-end engineers (who may be working in Spring Boot given the nice-to-have requirements). The presence of Kafka and Microservices as preferred skills suggests a distributed, event-driven architecture — this is not a small CRUD app shop. The inclusion of Azure DevOps points to an established CI/CD pipeline, and the expectation of Gradle familiarity indicates a Java-adjacent build environment on the back end. The hard on-site requirement (5 days/week, Glen Allen) and the emphasis on local candidates strongly suggests this team values in-person collaboration, likely due to the mission-critical nature of the systems or security and compliance requirements in their industry.
