Ui Software Developer Jobs in Gaithersburg, MD (NOW HIRING)

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.

What You'll be Owning

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.

The Software Engineer develops, maintains, and enhances complex and diverse software systems (e.g., processing-intensive analytics, novel algorithm development, manipulation of extremely large data sets, real-time systems, and business management information systems) based upon documented requirements. Works individually and as part of a team. Reviews and tests software components for adherence to the design requirements and documents test results. Resolves software problem reports. Utilizes software development and software design methodologies appropriate to the development environment. Provides specific input to the software components of system design to include hardware/software trade-offs, software reuse, use of Commercial Off-the-shelf (COTS)/Government Off-the-shelf (GOTS) in place of new development, and requirements analysis and synthesis from system level to individual software components.

In this capacity, the UI Developer will:

• 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

What You Must Have

• 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 GovCloud 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

Additional Skills & Experience That Would be Nice to Have

• 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 functional standards
• Assist with developing and executing test procedures for software components
• Develop software solutions by analyzing system performance standards, confer with users or system engineers; analyze systems flow, data usage and work processes; and investigate problem areas
• Modify existing software to correct errors, to adapt to new hardware, or to improve its performance
• Design, develop and modify software systems, using scientific analysis and mathematical models to predict and measure outcome and consequences of design
• Design or implement complex algorithms requiring adherence to strict timing, system resource, or interface constraints; Perform quality control on team products
• Implement recommendations for improving documentation and software development process standards
• Oversee one or more software development teams and ensure the work is completed in accordance with the constraints of the software development process being used on any particular project
• Confer with system engineers and hardware engineers to derive software requirements and to obtain information on project limitations and capabilities, performance requirements and interfaces
• Coordinate software system installation and monitor equipment functioning to ensure operational specifications are met
• Recommend new technologies and processes for complex software projects
• Serve as the technical lead of multiple software development teams
• Select the software development process in coordination with the customer and system engineering
• Ensure quality control of all developed and modified software
• Delegate programming and testing responsibilities to one or more teams and monitor their performance
