About The Position

GovCIO is hiring a Frontend Developer to build and modernize federal applications on a serverless AWS GovCloud stack. The position is remote within the Continental United States (CONUS). The developer begins with a focus on frontend work and is expected to grow into a full-stack role. Working within a cross-functional product team alongside designers, backend developers, DevOps engineers, and test engineers, the developer builds and maintains modern web applications using JavaScript, React, and Redux, integrating them with REST APIs on a serverless AWS backend. The role is hands-on and deadline-driven, with work planned and completed within sprints. Developers work from user stories and designer wireframes to build accessible and secure user interfaces, while understanding how the frontend and serverless backend fit together. As the role grows into full-stack development, the developer will build backend services with Python and AWS serverless technologies such as API Gateway, Lambda, and Step Functions. The work also includes integrating AI features using large language models and vision models, and building applications that handle non-deterministic AI output.
