OverviewLMI is looking for a Full Stack Developer to help build and extend IronSled, a PaaS focused on hosting applications in secure environments. You’ll be an initial member of a small, cross-functional team maintaining this product on contract. This position requires the ability to obtain a clearance; U.S. citizenship is required. This is position includes quarterly travel for in person team planning and collaboration events.
This isn’t a maintain-the-backlog role. You’ll work across the stack, own features end-to-end, and help shape how this solution is built for long term success for our clients.
What You’ll Do
- Build and ship full stack features across an Angular frontend and the IronSled TypeScript/Express API — from the database schema to the screen a user clicks.
- Design and implement how data moves through the platform — pipeline events, security scan results, container inventories, and project metadata — modeled in PostgreSQL and exposed through a clean API.
- Integrate and maintain connections to external systems as core execution flows: GitLab pipeline webhooks, Okta and Entra identity sync, OIDC/SAML authentication, Trivy security scanning, S3 artifact uploads, and Fleet GitOps repositories.
- Contribute to backend architecture decisions around data modeling, identity and permissions, security posture (vulnerability rollups, SBOM, FIPS 199 categorization), and how the platform handles sensitive federal data.
- Collaborate directly with the product manager in working sessions — shaping onboarding flows, dashboards, and UX decisions, not just implementing tickets handed to you.
- Ship incrementally and stay close to users. Get features in front of people, iterate on real feedback, and cut releases on a steady cadence rather than perfecting in isolation.
What We’re Looking For
- 3+ years of full stack development experience, or fewer years with demonstrable depth in ETL solutions; comfortable owning both frontend and backend
- Proficiency in Angular and TypeScript on the frontend
- Solid backend experience in Node.js and/or Python
- Experience using PostgreSQL to store, retrieve, and manage structured application data, with experience in database design, SQL development, and operational support
- 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
- Ability to move fast and iterate without heavy specs or detailed tickets
- This position requires the ability to obtain a clearance; U.S. citizenship is required
What Will Set You Apart
- A portfolio of side projects, personal websites, open-source contributions, or other evidence of a builder’s disposition; we care more about what you’ve built than where you’ve worked
- Demonstrated fluency with AI coding tools and a workflow that treats them as force multipliers, not novelties
- Experience across AWS, Azure, GCP, and on-premises environments.
- Experience developing software in environments governed by federal security and compliance requirements, with attention to secure coding practices, access control, auditability, and deployment constraints
