UI Front End Software Engineer

What Impact You'll Have

GRVTY is seeking an experienced UI Front End Software Engineer (SWE3) in support of CODEX, directly meeting mission‑critical needs in partnership with mission customers. This individual will lead a team of UI developers, designing front‑end architecture and coding standards while remaining hands‑on in development across the full software product lifecycle in an agile environment. Responsibilities span analyzing user requirements to derive design and performance standards, developing and debugging software, integrating systems, and implementing algorithms to meet performance goals.

The ideal candidate has front‑end experience, translates UX/UI designs into accessible, production‑ready interfaces, and mentors junior developers while collaborating closely with system engineers and product stakeholders to resolve technical problem areas.

GRVTY is seeking a UI Front End Software Engineer with a TS/SCI + Poly clearance (applicable to this customer) to join one of our top projects in Annapolis Junction, MD.

• Lead and mentor a team of UI/front‑end developers, providing technical guidance, standards, and code review
• Architect and implement scalable, maintainable front‑end solutions using modern frameworks
• Translate prototypes and design specifications into functional, responsive, and accessible interfaces
• Collaborate with backend engineers to design and integrate APIs, ensuring efficient data flow between front‑end and back‑end systems
• Contribute to full‑stack development efforts as needed, including backend services, database interactions, and deployment pipelines
• Establish and enforce front‑end coding standards, best practices, and component reuse across the team
• Partner with UX/UI and systems engineers to ensure design intent is preserved through implementation
• Identify and resolve performance bottlenecks, cross‑browser issues, and technical debt
• Participate in sprint planning, technical estimation, and architectural decision‑making
• Ensure compliance with accessibility standards (e.g., Section 508, WCAG) throughout development

• Active TS/SCI with Polygraph Clearance (applicable to this customer)
• 12 years of experience as a SWE in programs and contracts of similar scope, type, and complexity
• Bachelors degree in Computer Science or related discipline from an accredited college or university is required; 4 years of additional SWE experience on projects with similar software processes may be substituted for a bachelors degree
• 7 years of experience in Software Database and Repository Interface Development
• Proven experience leading or mentoring a development team
• Strong proficiency in modern front‑end frameworks (e.g., React, Angular, Vue) and standard web technologies (HTML, CSS, JavaScript)
• Full‑stack experience, including backend development (e.g., Node.js, Python, Java, RESTful/GraphQL API design)
• Experience with state management, component‑based architecture, and responsive design
• Familiarity with version control (Git) CI/CD pipelines, and cloud environments (AWS, Azure, or Gov Cloud is a plus)
• Experience working closely with UX/UI and systems engineers to ensure accurate implementation of accessible interfaces
• Experience working with tiered architectural systems and in a Linux/Ubuntu environment is a plus

• Analyze user requirements to derive software design and performance requirements
• Debug existing software and correct defects
• Provide recommendations for improving documentation and software development process standards
• Design and code new software or modify existing software to add new features
• Integrate existing software into new or modified systems or operating environments
• Develop simple data queries for existing or proposed databases or data repositories
• Write or review software and system documentation
• Serve as team lead at the level appropriate to the software development process being used on any particular project
• Design or implement complex database or data repository interfaces/queries
• Develop or implement algorithms to meet or exceed system performance and…
