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

The Sensors Division develops advanced solutions in radar, space-based sensing, electronic warfare, and underwater acoustics. Within the Space Missions and Sensing (SMS) Sector, we focus on advancing space sensing, space control, and counter-sensing technologies for critical national security missions.

The Role: Lead Modeling & Simulation (M&S) Engineer for Space Sensing

In this position, you will design, implement, and operate integrated simulation testbeds for advanced space and defense systems. Your work will include analyzing integrated system performance, developing and executing test plans, and defining system evaluation criteria. You will work closely with both research and software teams to integrate simulation and analysis tools and collaborate with customers to understand key challenges and needs.

What you will do: 

  • Design and apply cutting-edge models and simulation frameworks to support test and evaluation of algorithms, command & control systems, and deployed software solutions
  • Interact closely with customers to understand needs & requirements and to communicate technical results
  • Lead diverse teams and technical leadership to understand system level requirements and broad objectives; summarize progress, report on findings and provide assessments.
  • Lead business development initiatives and proposal writing efforts, playing a key role in shaping the proposed technology solutions

Who You Are: 

  • Ability to obtain and maintain a Secret security clearance, for which U.S. citizenship is needed by U.S. Government
