Full Stack Developer

Overview

We’re looking for a full stack developer to help build and extend LIGER, an enterprise AI platform that connects knowledge, systems, and agentic workflows to accelerate outcomes across federal missions. You’ll join a small, cross-functional team shipping a ground-up product redesign – and increasingly, building the agentic capabilities that make LIGER genuinely powerful.

This isn’t a maintain-the-backlog role. You’ll work across the stack, own features end-to-end, and help shape how AI agents are integrated into workflows that real users depend on. If you’re excited about building systems where models do real work – not just generate text – keep reading.

About This Team

LIGER sits within LMI’s Chief Technology Office. We’re a small, high-visibility team building AI tools for federal agencies. The culture is more startup than traditional government contractor – we move fast, solve problems in design spikes rather than scheduled reviews, and care more about outcomes than process. That said, we’re building for users who need reliability and trust, so craft and attention to detail matter.

You’ll work daily with our designer, engineering lead, and product team. The agentic layer of LIGER is still being shaped – this is a real opportunity to define how it gets built.

Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value.

What You'll Do

• Build and ship full stack features across frontend (Angular, Typescript), backend (Node/Python), and the integration layer between them
• Design and implement agentic workflows: tool-calling, multi-step reasoning pipelines, and the infrastructure that makes them reliable
• Use AI coding tools as a daily part of your development workflow
• Integrate and maintain connections to external services, data sources, and APIs as part of agent execution flows
• Collaborate directly with our designer and engineering lead in working sessions – you’ll shape UX decisions, not just implement them
• Contribute to backend architecture decisions around agent orchestration, state management, and LLM interaction patterns
• Ship incrementally and stay close to users – we care about getting things in front of people, not perfecting in isolation

What We're Looking For

• 3+ years of full stack development experience, or fewer years with demonstrable depth in agentic or LLM-native development – comfortable owning both frontend and backend
• Experience using Postgre
  
  SQL to store, retrieve, and manage structured application data, with experience in database design, SQL development, and operational support
• Proficiency in Angular and Type Script on the frontend
• Solid backend experience in Node.js and/or Python
• Hands-on experience building with LLMs (prompt engineering, API integration, tool use, and managing model outputs in production)
• Active use of AI-assisted development tools in your day-to-day coding workflow
• Experience designing and developing RESTful APIs and backend services that support scalable, maintainable integration across distributed application components
• Familiarity with agentic patterns: orchestration, tool-calling, retrieval-augmented generation (RAG), or multi-step agent flows
• Ability to move fast and iterate without heavy specs or detailed tickets

• A portfolio of side projects, personal websites, open-source contributions, or…
