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.
What You’ll Do
- Design, develop, test, and integrate frontend software features.
- Build responsive user interfaces using React and TypeScript.
- Develop map-based and geospatial visualization features using Cesium.
- Connect frontend components to APIs and services built with FastAPI and Flask.
- Turn complex mission and technical information into clear, usable workflows.
- Present application data and AI-enabled outputs in ways users can understand and use.
- Work within GitLab and OpenShift-based development environments.
- Apply secure software-development practices throughout implementation and testing.
- Write and maintain automated unit and integration tests.
- Participate in code reviews, technical reviews, and design discussions.
- Document application workflows, design decisions, interfaces, and test results.
- Collaborate with backend, AI/ML, security, platform, DevSecOps, and customer engineering teams.
What You’ll Bring
- Bachelor’s degree in Computer Science or a related field.
- At least four years of professional software-development experience.
- Hands-on experience building frontend applications with React and TypeScript.
