About The Position

LMI is seeking a Full Stack Developer to contribute to the development and expansion of IronSled, a Platform-as-a-Service (PaaS) designed for hosting applications in secure environments. As an early member of a small, cross-functional team, you will be responsible for maintaining this product under contract. The role requires the ability to obtain a security clearance, and U.S. citizenship is mandatory. This position involves quarterly travel for in-person team planning and collaboration events. This is not a role focused on backlog maintenance; instead, you will work across the entire technology stack, take ownership of features from conception to completion, and play a key part in shaping the solution's long-term success for our clients. The IronSled team is part of LMI’s Chief Technology Office and is building an ETL for federal agencies. The team operates with a startup-like culture, emphasizing speed, problem-solving through design spikes, and focusing on outcomes over rigid processes, while still prioritizing reliability and attention to detail for users who require trust. You will collaborate daily with the Product Manager, Engineering Lead, and Product Team. The roadmap for IronSled is still evolving, offering a prime opportunity to influence its direction. LMI is a digital solutions provider focused on accelerating government impact through innovation and speed, utilizing commercial-grade platforms and mission-ready AI for federal agencies. The company serves defense, space, healthcare, and energy sectors, helping agencies manage complexity and adapt to change. Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results.

Requirements

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
Applicants must meet eligibility requirements for a U.S. Government security clearance. Only US Citizens are eligible for a security clearance. For this position, LMI will only consider applicants with security clearances or applicants who are eligible for security clearances, due to the nature of the work.

Nice To Haves

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

Responsibilities

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.
