Lead Mission Software Engineer

A Mission Software Engineerdevelops and deploys software essential for a specific, real-world objective or "mission" in partnership with our customers. This approach differs from standard software engineering by placing a strong emphasis on the end-user's operational needs and the success of the overall mission, rather than just technical performance. Ensuring alignment to the mission and customer through an agile response to dynamic priorities can significantly improve the impact of STR software.

STR’s Analytics and Command & Control (AC2) Division focuses on developing actionable, advanced technology solutions to provide asymmetric advantages within the information domain. The Mission Applications (MA) Group within the AC2 Division specializes in ensuring the STR technology produces outsized mission impact. MA team members are comprised of Dev Sec Ops  Engineers, Mission Software Engineers, Product Managers, and Program Managers. MA staff matrix with scientists and engineering staff from the various STR R&D groups to form dedicated product teams that are laser focused on the operational transition of cutting‑edge software technologies.

As a Mission Software Engineer in the Mission Applications Group, you will work as part of tightly knit Agile software teams to develop, integrate, and maintain software systems that are deployed to customer locations. You ensure that our software solutions meet the highest standards of quality, reliability, and performance as well as user needs.

This position requires an active Top Secret (TS) clearance. The role can be based at any of these three STR sites:
Dayton, OH, Arlington, VA, and Woburn, MA. Applicants should expect to work on site at a Government facility in Northern California up to 1 week per month.

• Develop new software components for a key operational capability
• Conduct software integration and test activities in supporting a small integrated development team
• Perform integration testing to ensure seamless interaction between different system components
• Deployment and Field Testing:
  Traveling to integration sites to build, test, and deploy software in real‑world, operational environments (CONUS)
• Triage and Debugging:
