Test System Engineer III

Playa Vista, California, United States

Turning Space into a Transportation Layer for Earth

Who We Are: 

Eras of humanity can often be defined by a dominant transportation mode - horse-drawn chariots, ocean-going boats, or aircraft. These were spurred by a small group of people rigorously focused on building technology to achieve faster access to more of the world. We seek to usher in a new era of humanity defined by universal access to the whole globe free of borders and the presence of a routine way from space to Earth. To do this, we are building highly maneuverable re-entry vehicles that can loiter in orbit before precision landing back on Earth.  

What You’ll Do:

As an Avionics Test Systems Engineer, you will design, develop, and maintain high-precision test systems for Inversion’s next-generation spacecraft, Arc. Your expertise in designing hardware test platforms and software frameworks will directly impact flight hardware validation, qualification testing, and overall mission success by ensuring avionics meet performance, reliability, and environmental requirements. You will be a key member of the Avionics team, reporting directly to the Director of Engineering, Avionics.

  • Competence in developing test plans and authoring test/verification procedures for electronic systems.
  • Hands-on ability with oscilloscopes, signal generators, logic analyzers, and other lab equipment for debugging and characterization.
  • Strong proficiency in scripting languages such as Python and MATLAB for test automation and data analysis.

Desired Qualifications:

  • Background in automated data analysis tooling to improve test efficiency and insight generation.
  • Familiarity with embedded software development for microcontrollers or FPGA-based platforms.
  • Knowledge of PCB design for test instrumentation and interface hardware.
  • Understanding of EMI/EMC test methodologies for aerospace electronics.
  • Capability to automate environmental test equipment (e.g., thermal chambers, vacuum chambers).
  • Familiarity with CI/CD pipelines for test and verification automation.
  • Previous involvement in startup environments, where adaptability and initiative are critical.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

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.
