Company Overview:

Relativity is the first and only company to automate aerospace manufacturing by integrating intelligent robotics, software, and proprietary metal 3D printing technology. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. Our long-term goal is to upgrade humanity’s industrial base on Earth and on Mars.


The Avionics Instrumentation team is responsible for identifying and implementing vehicle sensor requirements across Terran 1 and Terran R launch vehicles. As an Instrumentation Engineer, you will work collaboratively with vehicle teams such as Propulsion, Fluids, Thermal, and Dynamics to develop instrumentation requirements to provide them the high-quality data required to successfully launch a 3D-printed rocket to orbit. This will involve working closely with the Avionics Hardware and Avionics Integration teams to ensure avionics capability to support sensor and actuator needs; and with the Integration team to ensure sensors and actuators are correctly installed, calibrated and functional-checked on the launch vehicle.

What you’ll do:

  • Work with Propulsion, Fluids, Structures, Flight Sciences, and other teams to identify and develop vehicle instrumentation requirements
  • Identify sensors and actuators such as pressure transducers; RTDs; thermocouples; accelerometers; solenoid valves; etc. that are suitable for use on the Terran 1 and Terran R launch vehicles
  • Collaborate with Avionics Hardware engineers to ensure designed system meets instrumentation requirements such as ranges, resolutions, sample rates, and cutoff frequencies
  • Maintain electrical interface and sensor/actuator configuration control: naming and channelization, serial numbers, calibrations, and data acquisition settings
  • Develop and execute on-vehicle sensor calibration and checkout plans
  • Oversee procurement, qualification, and acceptance testing of vehicle instrumentation
  • Up to 25% travel to our test and launch sites in Stennis Space Center, MS and Cape Canaveral, FL

What you need to know:

  • Bachelor's degree or higher with a focus in an engineering discipline: aerospace, electrical, mechanical, etc.
  • 3+ years of experience with development and integration of instrumentation and data acquisition systems for complex, mission-critical products (flight test, rocket launch systems, automotive, large-scale manufacturing, robotics, etc.)
  • Experience with sensors and actuators such as pressure transducers, RTDs, accelerometers, strain gages, frequency-to-DC sensors, microphones, thermocouples, solenoid valves, etc.
  • Excellent understanding of instrumentation and data acquisition fundamentals: measurement theory, Nyquist sampling theorem, DC circuit basics, grounding and shielding, analog-to-digital conversion
  • Demonstrated ownership, accountability, and success in delivering complex products with minimal guidance
  • Strong interpersonal communication skills

Nice to haves but not required:

  • Experience writing test plans and documentation
  • Familiarity with scripting languages such as Python or MATLAB for data acquisition, recording, and analysis
  • Experience with instrumentation in harsh environments (cryogenic temperatures, high vibration)
  • Previous experience with COTS data acquisition systems such as NI, Curtiss-Wright, Safran, or Beckhoff
  • Understanding of digital buses such as Ethernet, CAN, I2C, SPI
