Full Stack Software Engineer (Tech Lead) - Clearance Preferred

LMI is a digital solutions provider delivering innovative technology and mission-ready platforms for government agencies. The Full Stack Tech Lead will lead the logistics application team, own scalable edge-to-cloud systems architecture, mentor engineers, and make full-stack design decisions while contributing hands-on code. The role also involves building secure, tested, and production-grade frontend and backend systems for military and government users.

Responsibilities:

• Own the end-to-end systems architecture for a scalable, resilient data ingest pipeline spanning edge and cloud, built on Redis, RabbitMQ, and custom services
• Lead and mentor a team of frontend and backend engineers, guiding technical decisions, conducting code reviews, and establishing best practices and documentation
• Drive full-stack systems design decisions, from distributed data flows and message queuing to API architecture, data models, and UI component structure
• Lead an AI-enabled development team, owning the guardrails, validation layers, end-to-end tests, and supporting systems that keep AI-assisted output safe, reliable, and production-grade
• Break down product and design requirements into clear, workable, well-scoped engineering tasks and distribute them effectively across the team
• Build intuitive, responsive front-end experiences using React and modern component libraries, translating requirements into clean, reusable UI components
• Write clean, secure back-end services using C# / .NET, with a focus on REST APIs, modular design, and optimized data access layers using Entity Framework
• Collaborate across design, product, DevSecOps, and field teams to launch features quickly and securely
• Drive rapid prototyping cycles while enforcing production-grade coding standards across the team
• Champion automated testing and code quality gates by writing and reviewing unit, integration, and end-to-end tests
• Troubleshoot bugs, squash performance bottlenecks, and help build toward FedRAMP and IL5 deployment requirements

Requirements:

• 6+ years of relevant software engineering experience, including prior experience leading or mentoring engineers
• Demonstrated ownership of systems architecture and design for distributed, scalable systems—ideally data ingest or streaming pipelines spanning edge and cloud environments
• Hands-on experience with distributed systems components such as Redis, RabbitMQ (or comparable message brokers), and custom service development
• Experience leading an AI-enabled development team, including owning the guardrails, validation, end-to-end testing, and support systems needed to safely and reliably ship AI-assisted work
• Full stack proficiency across frontend and backend, with demonstrated ability to make architectural decisions spanning both
• Strong frontend skills: React (component design, hooks, modern front-end patterns), JavaScript/TypeScript, and a solid grasp of HTML, CSS, and responsive design principles
• Strong backend skills: C# and modern .NET, with hands-on experience in Entity Framework and relational databases, plus a solid understanding of SQL, indexing, and query optimization
• Familiarity with dependency injection, async/await, and LINQ
• Deep understanding of systems design and the relationship between frontend and backend systems, including state management, REST APIs, async data fetching, and event-driven/asynchronous messaging patterns
• Experience with testing tools across the stack (e.g., Jest, Vitest, React Testing Library) and a track record of building automated validation and end-to-end testing into delivery
• Proven ability to turn product and design requirements into workable, well-scoped engineering tasks
• Familiarity with secure software development practices and CI/CD pipelines (GitHub Actions, GitLab, etc)
• Comfortable leading in Agile or Lean environments, with rapid delivery cycles and direct user feedback loops
• US Citizenship with the ability to obtain and maintain a government security clearance
• Hands-on work with secure government environments (DoD, IL5+, FedRAMP)
• Experience building logistics, supply chain, or asset tracking applications
• Certifications like Security+ and AWS Developer/Architect
• Past experience at a startup or in rapid-growth teams
• Active Secret or TS clearance preferred
