Senior Mechanical Engineer

Woburn, MA

About the Team:

STR’s Space Missions and Sensing (SMS) Sector’s mission is to develop and apply innovative technology to space-based sensing, space control, and counter-sensing. Within the SMS Sector, the Space and Counter Space (SCS) team is at the forefront in electronic warfare technologies.  Our team strives to bring critical and transformational capabilities to the warfighter through creative ideas and techniques.  To realize the value, the team develops both engineering and operational prototypes to demonstrate capabilities in real world environments. 

STR takes pride in our ability to address warfighter operational needs. Our core team includes principal investigators, program managers, signal processors, SW developers, FPGA expertise, RF and Electromagnetic engineers, and mechanical design experts.  Our facilities support on site build and test (benchtop, anechoic chamber, and over the air).  We collaborate with a dynamic group of research engineers across STR, academic researchers, and industry partners to develop practical and effective solutions to RF sensing and counter-sensing challenges.

The work program is growing, with strong demand signal from our sponsors.  We are seeking mechanical engineering design, development, and integration support for advanced and operational prototype systems. If you're seeking an opportunity to apply your deep technical knowledge and creativity to make a lasting impact in national security, we invite you to join us. 

The Role:

As a Senior Mechanical Design Engineer, you will have the opportunity to work with a team to design, build, integrate, and test sensing and counter sensing systems for radar, electronic warfare, sonar, and other applications. Systems predominantly field deployable prototypes with the objective of transitioning to low-volume product systems.

Who you are:

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
