Frontend Software Engineer — Secure Mission Systems
Location: Mainly remote, with onsite work in Laurel, Maryland, typically one day approximately every six weeks for team-wide sprint planning
Clearance: Active final DoD Secret clearance required
Build Secure Software for High-Impact Defense Missions
Build secure, interactive software that helps users understand complex information, evaluate options, and support mission-planning decisions.
As a Frontend Software Engineer at Rackner, you will develop modern application features for secure mission-planning and decision-support software. You will build responsive user interfaces using React and TypeScript, support geospatial visualization using Cesium, and connect frontend components to services built with FastAPI and Flask.
This role gives you broader ownership than isolated interface tickets. You will contribute across application development, API integration, automated testing, secure software delivery, documentation, and technical reviews while working with experienced software, AI/ML, security, platform, and customer engineering teams.
This position is contingent upon contract award and final customer approval.

Why Rackner
At Rackner, you will have the opportunity to build secure technology that supports critical defense and public-sector missions.
You will work on more than isolated frontend requirements. This role brings together hands-on software development, interactive data experiences, secure delivery, API integration, and close collaboration across frontend, backend, AI/ML, security, platform, and mission-focused teams.
Rackner has delivered more than $30 million in recent federal awards and supports mission-critical work across defense, civilian, and public-sector environments. We are looking for a Frontend Software Engineer who can build on that momentum by making complex information easier to understand, navigate, and act on.
Benefits & Professional Growth
Apply
If you are a frontend engineer who wants to expand your impact across secure software, modern React and TypeScript development, data-rich interfaces, and mission-focused applications, we would like to hear from you.
