Power Electronics Systems Engineer

Position: Staff Power Electronics Systems Engineer
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. Role Summary We are looking for an experienced Systems Engineer to join our team developing the power electronic components going into Rivian's future electric vehicles and DC Fast Chargers. This role requires a technical background in power electronics and a strong understanding of electric vehicle systems.

The ideal candidate will have development experience with Traction Inverters, On-board Chargers (OBCs), DC-DC Converters or DC Fast Charger AC-DC power conversion electronics. As a key member of a Product Development Team, you will have responsibilities over the full product lifecycle, from initial design conceptualization and requirements definition to production support. Responsibilities Translate high-level vehicle requirements into detailed, actionable system and component-level specifications Define and manage system-level requirements for new EV power electronics products, ensuring alignment with vehicle-level performance, safety, and regulatory standards Ensure upstream and downstream traceability between hardware, software, systems, technical requirements, and relevant test cases within the requirement management tool Leverage simulation tools (e.g., MATLAB/Simulink, Ansys, PLECS) to guide or perform design analysis, model system behavior, and derive robust requirements Analyze and advise on technology options and conduct trade studies Lead DFMEA efforts with a cross-functional mix of product development team members Take a primary role in subsystem and vehicle integration activities and work with the product development team to resolve integration issues Resolve systems (hardware/software) related failures and develop short- and long-term corrective plans Act as the primary technical interface with internal and external stakeholders, including the vehicle integration teams Contribute to the development of acceptance test and validation test specifications and procedures Collaborate with the Rivian test teams to develop comprehensive validation plans employing test methods at the HIL, Unit, System, and Vehicle test levels Assist in resolving issues uncovered during the product validation testing Develop, execute, and document results for vehicle-level validation tests that address requirements owned by the product development team Work with hardware design, controls, software, and test engineering peers to achieve world-class product results Participate in roadmap planning for future products Champion best practices in systems engineering, including requirements management, failure mode and effects analysis (FMEA), and risk mitigation Report out the Systems Engineering deliverable status to the Product Development and leadership teams.
