Front-End Developer - Clearance Required

Summary

LMI is a digital solutions provider delivering technology and mission-ready solutions to federal agencies. The company is seeking a mid-level Front-End Developer to translate human-centered design research and prototypes into production-quality interfaces for DoD mission applications. The role also involves owning reusable UI components, integrating RESTful APIs, applying accessibility and responsive design standards, and collaborating closely with HCD researchers and full-stack developers.

Responsibilities

• Implement validated HCD designs, translating wireframes, annotated prototypes, and design specifications into production-quality front-end code with high fidelity to the research-validated user experience
• Own the component layer, building a reusable, maintainable UI component library that can carry forward across successive mission application builds
• Collaborate directly with the HCD researcher throughout build, flagging when technical constraints affect design intent, proposing alternatives, and keeping implementation honest to what usability testing validated
• Integrate front-end components with RESTful APIs provided by the full-stack developer, ensuring data flows surface correctly in the user interface
• Apply accessibility standards and responsive design principles appropriate for classified government environments
• Ship incrementally and stay close to users, getting things in front of people rather than perfecting in isolation

Skills

• Active DoD Secret clearance
• 3+ years of front-end development experience with demonstrated proficiency in React, JavaScript, HTML5, and CSS3
• Genuine fluency in HCD and UX principles, not just familiarity with the terms, but demonstrated experience working within a human-centered design process and building to validated design outcomes
• Experience working directly alongside UX researchers or HCD practitioners, translating research-validated wireframes and prototypes into front-end code with high fidelity
• Experience building and maintaining reusable component libraries or design systems
• Experience integrating front-end applications with RESTful APIs
• Strong understanding of responsive design, accessibility standards (WCAG), and performance optimization
• Ability to move fast and iterate without heavy specs or detailed tickets
• Experience developing software in DoD or IC environments governed by federal security and compliance requirements, secure coding practices, access control, auditability, and deployment constraints in accredited systems
• Hands-on experience with AWS GovCloud and DoD-accredited DevSecOps platforms, understanding of how classified environment constraints affect front-end tooling and deployment
• Experience building on platforms up to IL6, or familiarity with DoD Impact Level requirements and how they shape front-end architecture decisions
• Experience contributing to or leading a component library or design system that served multiple applications or product lines
• A portfolio of work that demonstrates both technical execution and design sensibility; we want to see that you can tell the difference between a good and a bad user experience, and that your code reflects it
• SOF operator or SOF-support background with understanding of SOF core activities and mission sets
