Frontend Software Engineer — Secure Mission Systems

Frontend Software Engineer — Secure Mission Systems

Build Secure Software for High-Impact Defense Missions

Build secure, interactive software that helps users understand complex information, evaluate options, and make mission-critical decisions.

As a Frontend Software Engineer at Rackner, you will develop modern application features for a secure mission-planning and decision-support platform supporting a Department of Defense customer. You will translate complex data and technical requirements into clear, responsive user experiences using React, TypeScript, and related technologies.

This is a primarily remote role within the United States. Work will be performed through customer-provided systems, with virtual collaboration across the engineering team and in-person sprint planning at a customer facility in Laurel, Maryland, approximately every six weeks.

You will work on more than isolated interface tickets. This role gives you the opportunity to deepen your experience across secure frontend development, API integration, data-rich applications, automated testing, and collaboration with backend, AI/ML, security, and platform engineers.

This position is contingent upon contract award and final customer approval. The anticipated start date is November 2026.

What You’ll Do

Build interactive frontend features using React and TypeScript

Turn complex mission and technical information into clear, usable workflows

Connect frontend components to APIs and backend services

Support data-rich, map-based, and decision-support application features

Present application data and AI-enabled outputs in ways users can understand and act on

Write maintainable, testable code that meets functional and security requirements

Develop unit and integration tests for application features

Participate in code reviews, technical discussions, and security remediation

Document application workflows, design decisions, and technical changes

Collaborate remotely with backend, AI/ML, security, DevSecOps, and customer engineering teams

Participate in periodic onsite sprint planning and technical collaboration in Laurel

What You’ll Bring

At least four years of software-development experience

Hands-on experience building modern frontend applications

Experience working with React and TypeScript

Experience integrating user interfaces with APIs or backend services

Understanding of component-based development, application state, and data flow

Familiarity with Git-based development and secure software-development practices

Ability to write and test clear, maintainable code

Bachelor’s degree in computer science or a related field

Experience That Can Strengthen Your Fit

Experience with several of the following can improve alignment, but deep expertise in every area is not expected:

Cesium, CesiumJS, or another geospatial or mapping framework

Map-based, spatial, or data-visualization applications

OpenShift, Kubernetes, or another containerized environment

GitLab and secure CI/CD workflows

FastAPI, Flask, Python, or API development

Automated testing and vulnerability remediation

Defense, aerospace, command-and-control, or mission-planning software

Frontend integration of AI-assisted recommendations or decision-support capabilities

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.
