Instrumentation And Controls Engineer I (Build)

About the Team:

The Stennis Test team designs, builds, and operates Relativity's propulsion and stage test stands. Team members are hands-on with large-scale, complex systems including fully integrated engines and stage assemblies, pushing hardware to the limits and directly contributing to flight readiness. The work is fast-paced and highly operational, ideal for those with backgrounds in aviation, automotive, manufacturing, offshore operations, industrial systems, construction, or adjacent industries. You'll work in a close-knit, dynamic environment where collaboration between technicians, operators, and engineers is not only encouraged, but expected. As the company scales, the Stennis Test team becomes even more critical to unlocking our next phase of growth: proving out full-stage systems and paving the way for routine, reliable flights of Terran R.

About the Role:

• Design, integrate, and test acquisition hardware, instrumentation, and cameras used to support and control Terran R rocket test stands, including but not limited to Beckhoff PLCs or similar, pressure sensors, temperature sensors, flow meters, level sensors, accelerometers, solenoid valves, variable frequency drives (VFDs), heaters, and IP, SDI, and CoaXPress cameras.
• Design and maintain electrical systems for use in hazardous areas.
• Participate in P&ID reviews, electrical one-line drawings, and control panel designs.
• Collaborate with cross-functional teams of engineers and technicians to support and execute projects.

About You:

• Bachelor's degree in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, or a related engineering discipline.
• Demonstrated fundamental knowledge of electrical engineering principles.
• Proven ability to successfully complete complex projects by coordinating with others and meeting deadlines.

Nice to haves but not required:

• Experience with data and control systems such as SCADA, PLCs, National Instruments, Beckhoff, or similar platforms.
• Experience integrating sensors and actuators including pressure transducers, RTDs, strain gauges, thermocouples, solenoid valves, accelerometers, and microphones.
• Familiarity with communication protocols such as Ethernet, EtherCAT, CAN, and Modbus.
• Experience with aerospace test operations, cryogenic fluids, or high-pressure gas systems.
• Proficiency with AutoCAD Electrical or other electrical CAD software.
• Knowledge of NFPA 70E and the National Electrical Code (NEC).

Successful candidates must clear a background check administered by the US government to obtain clearance for on-site work at our government partner location in Stennis, Mississippi.
