Avionics HITL Engineer

Company Details

Building humanity’s multiplanetary future.

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 team is responsible for all aspects of the electrical design on the rocket, from electronics, interconnects, associated mechanical design, testing and initial production of the first 3D printed rocket! This team’s scope includes the flight computers, power systems, RF systems, PCB design, autonomous flight safety systems, and telemetry. This team works on complex electrical systems that require modularity and flexibility, and are critical to the successful launch of Terran 1, Terran R, and beyond!

What you’ll do:

The Avionics HITL Engineer will be responsible for system-level and vehicle-level test of avionics hardware and software. They will support the design of hardware-in-the-loop test beds and auxiliary ground support equipment to enable powering and communicating with our rockets while they are in our factory, at our test sites, and on the launch pad. The Avionics HITL Engineer will coordinate and assist in the development of system, vehicle, and software test procedures. They will also support integrated test and checkouts of our flight vehicles at the factory, test site, and launch site. This person may also travel 10% to 20% of the time to support remote test sites and launch operations.

What you need to know:

  • Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering,
  • Computer Science, Aerospace Engineering, or a related field
  • 2+ years of experience with electronics hardware test, hardware-in-the-loop testing, or electronics design
  • Familiarity with a data acquisition and control system platform such as LabView, Beckhoff, or similar
  • Experience developing basics scripts in a language such as Python or similar
  • Experience writing test plans, test procedures, and verification matrixes
  • Experience designing and building test racks to exercise hardware-under-test
  • Familiarity with integrating simulation models into test software to exercise hardware and software
  • Experience working in highly collaborative roles in cross-functional teams
  • Familiarity with basic electronics tools such as power supplies, digital multimeters, oscilloscopes, and electronic loads

Nice to haves but not required:

  • Experience in a startup or agile environment
  • Experience operating a complex vehicle such as a launch vehicle, satellite, or aircraft
  • Experience developing simulation software
  • Familiarity with common communication protocols such as Ethernet, CAN, etc.
  • Experience with high power and high voltage systems and batteries
  • Experience with wire harness design
