STR Harnesses the power of technology to solve the nation's hardest problems.
The Role

STR is focused on delivering national defense capabilities by driving mission-focused strategies to develop advanced technology systems that enable enduring products and solutions focused on achieving the customer vision. Our programs deliver sustainable, reliable, and cost-efficient capabilities focused on end-customer needs that function in operationally relevant environments and timeframes. We offer a dynamic and challenging environment where your work directly contributes to national security.  

We are seeking an Electro-mechanical Technician to support the design, development, testing, and implementation of high-visibility programs across STR. As an experienced technician, you will be expected to leverage your skills to assemble, evaluate/test, and maintain electrical/electro-mechanical systems. Experience with lab test equipment (e.g. oscilloscopes, impedance analyzers, and function generators) is desired. You will provide feedback to design teams to help improve the assembly and maintenance of the systems, as well as aid in trouble shooting and addressing any issues the system may encounter.  To be successful in this role, you should be able to read electrical system design plans and recommend improvements, as well as calibrate instruments, and diagnose faulty equipment. 

If you are driven by a passion for making an impact, excel in a collaborative environment, and are dedicated to the pursuit of excellence, we invite you to apply to join our team.

  • Solder, soldering irons, and crimp tools 
  • Connectors, wires, shrink sleeving, and epoxies 
  • Fastener torquing, staking, and general ruggedization of hardware 
  • Fault-testing equipment such as oscilloscopes, impedance analyzers, and function generators 
  • Test fixturing 
  • Support test activities under guidance from Engineering teams and/or conduct test routines independently.  
  • Read technical design/drawing packages and implement into hardware leveraging industry best practices.   
  • Create/revise/recommend changes to technical documentation and identify improvements for performance and/or manufacturability 
  • Accurately and completely document work activities to ensure design and manufacturing history is maintained 
  • Apply familiarity and experience (e.g., certification) with electronics industry assembly standards such as IPC (Aerospace and Defense applicable standards preferred) and skills such as soldering, crimping, and power tools (drill press, saws, etc.) 
  • Work/communicate with Engineering staff to understand design intent, communicate issues and corrective recommendations 
  • Assist lab manager in coordination of day-to-day activities within the laboratories, ensuring a clean, organized, and fully equipped environment for our team 
  • Assist in managing inventory of materials and supplies (e.g., chemicals, gloves) and equipment (track status; coordinate maintenance, calibration, and repair; schedule use) 
  • Aid in preparing space for program use (e.g., ensure benches and storage are available; power and network is suitable; ESD protections are in place) 
  • Aid in lab closeout upon program completion (e.g., pack/return equipment; clean space) 
  • Demonstrate proper equipment use while also ensuring equipment is properly used by others (e.g., verify function, conduct training or direct users to appropriate training)
