Hiring: Staff Powertrain NVH Engineer Company: Rivian Location: Plymouth, MI Job Posted Time: 2026-09-10 13:15:13 Employment Type: Full-time Target Skills & Keywords : MATLAB, Python About the job Experience: •10+ years (Staff) or 12+ years (Senior Staff) of experience in powertrain NVH, with demonstrated ownership of electric drive unit NVH development. Required Skills: •Lead powertrain NVH development across electric drive units, including electric motors, gearboxes, bearings, differentials, pumps, mechanical disconnect solenoids, housings, mounts, and vehicle integration. •Plan and execute component, subsystem, and vehicle-level NVH testing in both laboratory and on-road environments with a focus on electric powertrain sources and their interactions. •Perform sound power measurements for motors, gearboxes, pumps, and complete drive units to support target setting, benchmarking, and design validation. •Lead and apply Blocked Force Transfer Path Analysis (TPA) and traditional TPA methods to quantify source strengths from motors, gears, bearings, pumps, and disconnect mechanisms, and identify dominant NVH paths into the vehicle •Generate in-depth diagnostics using FRFs, modal analysis, and operating deflection shape (ODS) analysis to isolate structure-borne and airborne noise mechanisms across rotating and actuated powertrain components. •Analyze and influence electric motor NVH, including Permanent Magnet Synchronous Motors (PMSM) and induction motors, electromagnetic excitation, torque ripple, and rotor–stator interactions, rotor construction, skew strategies, and mechanical–electromagnetic coupling •Investigate and resolve NVH concerns related to bearings, gear meshes, differentials, pumps, and mechanical disconnect solenoids, including tonal noise, broadband noise, transient events, and order-related phenomena. •Lead NVH development of powertrain mounting systems, including rubber and elastomeric mounts, and evaluate mount tuning effects on system and vehicle NVH. Qualifications: •Bachelor’s or Master’s degree in Mechanical Engineering or a related field (advanced degree preferred). •Strong, hands-on background in NVH testing, including sound power, TPA, FRFs, modal analysis, and vehicle-level diagnostics. •Proven ability to lead NVH development programs, not just execute tests. •Comprehensive expertise in electric motor NVH, including PMSM and induction motor architectures. •Demonstrated experience diagnosing NVH related to bearings, gears, differentials, pumps, and mechanical disconnect systems. •High confidence in vehicle subjective assessments and the ability to correlate customer perception with objective engineering data. •Proficiency with modern NVH tools and data analysis environments, including Testlab, Artemis, MATLAB, and Python. •Strong technical judgment, ownership mindset, demonstrated ability to collaborate cross-functionally and ability to drive complex problems to closure in fast-paced development environments. •Excellent technical communication skills, with the ability to influence design decisions using data-driven insights. •The successful candidate may be eligible for annual performance bonus and equity awards. Compensation: •$140,600 - $175,800 / year •The successful candidate may be eligible for annual performance bonus and equity awards Interested candidates, please apply directly through the job posting on company's career page or try via AI auto apply on this platform.
