UX/UI Engineer

SAIC•Alexandria, VA

About The Position

SAIC is seeking a UX/UI Engineer to support Joint Engineering and Test Enterprise Portal (JETEP) software development activities, deploying tools, capabilities, and content. The role focuses primarily on UI/UX design and collaboration with requirements, development, and testing teams, while also contributing production frontend code using React and TypeScript. The engineer will work within the existing codebase to implement features, improve shared components, and resolve UI issues as priorities require. The role involves translating user needs, business rules, and UI requirements into practical designs; creating user flows, wireframes, mockups, and interactive prototypes in Figma; and designing new experiences while evaluating and improving existing interfaces. The engineer will document expected interface behavior, maintain consistent design patterns aligned with MUI and the application design system, and collaborate with developers to balance usability, technical feasibility, and delivery priorities. The UX/UI Engineer will partner with requirements analysts, stakeholders, developers, and testers to clarify interactions, define acceptance criteria and test scenarios, conduct design reviews and usability evaluations, and assess implemented interfaces against requirements and designs. The role also includes implementing and troubleshooting React/TypeScript components and UI features, integrating backend APIs, following established coding and review practices, and designing accessible interfaces that meet applicable Section 508 requirements and project accessibility standards. Participation in Agile planning, refinement, demonstrations, and reviews is expected.
