Front-End Developer - Clearance Required

Overview

LMI is looking for an experienced mid‑level Front‑End Developer to build and extend a portfolio of mission applications for a DoD customer on a DoD‑accredited cloud platform in AWS Gov Cloud. The role is hybrid with preference given to a San Diego, CA candidate and requires an active Secret DoD clearance.

• 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 the 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

• 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, with 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 Gov Cloud and DoD‑accredited Dev Sec Ops  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
