About the role

We are seeking a Senior Specialist Software Engineer who wants to stay hands-on building the software behind missions that matter. You will work on a wide range of projects, from modern full-stack web applications using React, TypeScript, JavaScript, Python, Docker, and Linux to embedded software integrated with unique hardware. Most assignments will focus on one of these two areas, depending on mission needs, while delivering dependable command-and-control capabilities that support customers and real-world assets. This is an individual-contributor role with opportunities to provide technical leadership, not a people-management position, and a chance to be part of something bigger than any single product.

Responsibilities

  • Design, develop, integrate, and sustain high-reliability command-and-control software supporting customer missions and real-world assets.
  • Build full-stack web applications using React, TypeScript, and JavaScript for responsive user experiences and Python services and APIs for backend capabilities.
  • Develop and deploy containerized software using Docker, applying object-oriented design to create clean, maintainable, and testable code.
  • Integrate software with unique hardware platforms and troubleshoot the interfaces, data flows, and runtime behavior that connect the two.
  • Configure and troubleshoot basic Linux development, deployment, and runtime environments in support of software delivery and sustainment.
  • Work directly with customers, systems engineers, and mission users to turn operational needs into practical technical solutions; contribute technical leadership through strong engineering judgment, design reviews, and peer collaboration.

Requirements

  • Bachelor’s Degree and minimum 6 years of prior relevant experience.
  • Graduate Degree and a minimum of 4 years of prior related experience.
  • In lieu of a degree, minimum of 10 years of prior related experience.
  • Active TS/SCI security clearance is required.

Skills

  • Hands-on full-stack web development experience.
  • React, TypeScript, JavaScript, and Python.
  • Docker and object-oriented programming.
  • Software-hardware integration.
  • Basic Linux configuration and troubleshooting.
  • Git, debugging, automated testing, and secure development practices.
  • Current CI Polygraph.
  • Custom hardware, edge-device, or control-system integration.
  • Command-and-control, mission, or real-time software.
  • Secure containerized web services and connected hardware.

Schedule

9/80 - Employees work 9 out of every 14 days – totaling 80 hours worked, and have every other Friday off.
