About The Position

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.

Requirements

Master's degree or advanced degree in Electrical Engineering, Systems Engineering, or a related field
Minimum of 8+ years of experience in Systems Engineering, preferably within the automotive or EV industry
Demonstrated ability to develop requirements based on simulations and model-based systems engineering (MBSE) principles
Experience with power electronic design and analysis, including semiconductor selection, thermal management, magnetics, and control algorithms
Understanding of the systems design architecture, hardware electronics design, and software architecture design of DC-AC Inverters, DC-DC Converters, and AC-DC power electronics applications
Proven understanding of on-board charging standards (e.g., J1772, CCS) and vehicle communication protocols (e.g., CAN)
Strong understanding of the automotive industry guidelines (e.g. ISO, IEC) and country-specific regulatory requirements applicable to electric vehicle on-board and off-board power electronic components
Knowledge of failure modes and failure effects of electronic hardware designs with an in-depth knowledge of DFMEA processes
Experience leading DFMEAs
Familiarity with functional safety processes and standards for safety-critical automotive systems (ISO 26262)
Understanding of hardware and software validation testing at various levels (SIL, HIL, Unit, and Vehicle).
Experience leading root cause analysis activities with techniques such as fault tree analysis and fishbone diagrams
Ability to work in a fast-paced development environment
Excellent communication, leadership, and problem-solving skills

Nice To Haves

Knowledgeable in vehicle-to-grid (V2G) and power export technologies, including relevant standards and use cases, is a plus

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.
