Sr. Test Technician III, Powertrain

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.

This role will be focused on operating and maintaining dynamometer test systems for the development and validation testing of electrified powertrain systems (drive units, gearboxes). The Dyno Technician will work closely with Powertrain Test Engineers to install, configure and maintain test properties across a variety of complex powertrain test equipment in order to execute and monitor testing to requirements specified by Powertrain Validation engineers.

Supported by the rest of the engineering team, you will be responsible for performing first‑line troubleshooting of any operational issues encountered on test and take ownership of delivering high‑quality test data to support high‑level Test & Validation plans for the products.

• Operate and maintain large dynamo meters (for vehicle and powertrain system level testing)
• Select and install instrumentation needed to collect response data from the product during testing (accelerometers, strain gauges, pressure gauges, thermocouples, thermistors, hygrometers, voltage drop sense leads, etc.)
• Build and setup test rigs/dynos for mechanical and/or electrical tests together with Powertrain, NVH, and Thermal engineering teams
• Perform routine maintenance to complex mechanical and electrical repairs.
• Take an active part in Environmental Health & Safety within the laboratory environment, contributing to Risk Assessments and ensuring a safe work environment
• Support Validation Engineers to perform upgrades and modifications to Systems Under Test
• Perform the first line of fault finding for operational issues which arise on System Under Test
• Perform diagnosis and repair of prototype vehicle’s electrical/mechanical/software systems
• Support Test Engineers to achieve test plans and test equipment upgrade projects
• Document and communicate findings through processes and systems, taking ownership of early escalation where appropriate
• Generate and take ownership of process documentation for test rigs and associated test equipment
• Provide feedback, create and implement processes and suggestions to new and/or improved workshop standards, protocols, and processes

• 5+ years of Technician Experience working directly in test cells and/or large dynamometer systems
• 2+ years of experience with electrified vehicles preferred
• Expertise in instrumentation (Thermocouples, RTDs, Strain Gauges, Accelerometers, Hygrometers, Pressure Gauges, Flow Meters)
• Expertise in powertrain test setup and test error proofing
• Expertise in mechanical tooling and build fixture design
• Knowledge of motor, inverter, and gearbox concepts
• Knowledge of propulsion systems and thermal (coolant and refrigerant) systems
• Knowledge of Electric Vehicle Safety
• Work under strenuous/awkward positions throughout the working day.
• Operate a variety of scan tools, diagnostic equipment, and common automotive test equipment
• Strong diagnostic and problem‑solving skills to solve powertrain system issues
• Someone that takes pride in their work
• Work in a team environment and communicate with fellow technicians
• Basic workshop etiquette, provide verbal and writing communication across all teams

Salary Range for California Based Candidates: $47.33/hr - $59.16/hr (actual compensation will be determined based on experience, location, and other factors permitted by law).
