About Rivian

Rivian is on a mission to keep the world adventurous forever. This goes for the emissions‑free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.

As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.

As a Test Engineer, you'll play a crucial role in the hardware design and development of automated PCBA and unit‑level test stations. This includes designing specialized test equipment for a range of power electronic equipment, such as inverters, onboard chargers, and DC fast chargers. You'll collaborate with automation engineers to automate end‑of‑line and validation test equipment, and you'll also contribute to the continuous improvement of our test stations for future programs.

• Architect and lead the design of complex functional test equipment for PCBAs and high‑voltage power electronics systems, owning designs from concept through production deployment
• Define and enforce test equipment design standards, best practices, and reusable design patterns across the team.
• Author and review electrical wiring schematics, and serve as a technical reviewer on other engineers' design documentation
• Partner directly with hardware and software engineering project teams to align test system architecture with product requirements
• Lead design reviews, requirement reviews, DFMEAs, PFMEAs, and Hazard Analyses as a contributor and as a technical reviewer
• Develop and approve test procedures, defining setup requirements, acceptance criteria, and measurement uncertainty considerations
• Drive data analysis methodologies and set reporting standards for the team; synthesize complex test results into actionable engineering recommendations
• Serve as the team's subject matter expert on electronic test instrumentation, including power supplies, oscilloscopes, multimeters, signal generators, power analyzers, and sensors (thermocouples, RTDs, strain gauges, accelerometers, pressure gauges, flow meters)
