Profile match
Systems and Technology Research is an American defence research company that develops sensing, autonomy and decision systems for United States government customers. Its engineers work on radar and electro-optical signal processing, multi-sensor fusion, machine learning applied to intelligence problems, autonomous mission planning and cyber capabilities, typically under research contracts with defence agencies rather than as a product vendor. Headquartered in Woburn, Massachusetts with offices in Arlington and Dayton, it employs mostly cleared technical staff and competes for work against the federally funded research centres and other defence laboratories.

About the Team:  

Information processing and sense-making systems are the lifeblood of national security efforts, facilitating an understanding of the global situation, strategic planning, and tactical execution. The reliability, accessibility, and sophistication of these systems can determine the outcomes of conflicts before they begin. 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 technology that STR creates produces outsized mission impact. Staff within the MA group have a deep understanding of missions and technology needs for national security with skills targeting transition of technology to operational use, including product management, UX Product implementation, software integration & mission engineering, platform engineering, DevOps, and program management. MA staff combine with other science and engineering staff from the various STR research and development groups to form dedicated product teams focused on accelerating the operational transition of cutting-edge software technologies. 

The Role:  

As a Mission Engineer (Full Stack) in the Mission Applications Group, you will develop and deploy software essential for a specific, real-world objective or "mission" in partnership with our customers. You have: 1) expertise in developing and deploying software solutions in complex and high-security environments, 2) deep domain knowledge in the complex missions executed across the Department of Defense, and 3) expertise in modern frameworks, building full stack applications, and integrating APIs for deployment in high-security environments. 

You will work as a leader of software teams to design, develop, and maintain software systems deployed in operational use. You have experience managing customer relationships while simultaneously leading engineering teams to ensure the delivered product meets the highest standards of quality, reliability, and performance.

What you will do:

  • Build Prototype Capabilities: Break down use cases and user-defined problems, build an MVP, and rapidly evolve a solution into a cohesive application
  • Develop and Enhance Features: Create high-performance, visually appealing frontend solutions that handle complex use cases effectively. Ensure the product is fast, smooth, and intuitive to use, even under heavy load
  • System Integration: Leading cross functional engineering teams to design, build, and deploy a cohesive system. Integrate independent capabilities into existing solutions
  • Customer Collaboration: Working closely with end-users and customers, who are typically military or Government operators, to understand their requirements and translate them into software features. You are experienced in product discovery best practices
  • Deployment and Field Testing: Traveling to integration sites to deploy, test, and triage software in secure operational environments.  On average, travel to customer sites should not exceed one week per month 

Who You Are:  

  • Active Secret Security Clearance with the ability to obtain Top Secret level with SCI Eligibility
  • BS in Computer Science or related technical field with at least 7 years of work experience. Equivalent experience will be considered
  • Experience deploying software for DoD or IC missions
  • A passion for crafting user-centric interfaces and a keen eye for design details
  • Demonstrated strong knowledge of modern technologies such as React, TypeScript, and Python
  • Knowledge of performance-focused tools and techniques for rendering large datasets and building responsive, smooth interfaces
  • A demonstrated ability to adopt new languages, libraries, and technologies
  • Organized, detail-oriented, and with an ability to work both independently and collaboratively
  • Demonstrated experience as an effective communicator to both technical and non-technical audiences 

Even Better:  

  • Advanced Degree in Computer Science, Information Technology, or related technical field
