The ideal candidate 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.

Primary Responsibilities:

• 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

Required Skills:

• Twelve (12) years’ experience as a SWE in programs and contracts of similar scope, type, and complexity is required.

• 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
• Familiarity with version control (Git) CI/CD pipelines, and cloud environments (AWS, Azure, or GovCloud is a plus)
