Staff Powertrain Nvh Engineer

Rivian Rivian · Auto · Plymouth, MI · Attributes

Rivian is seeking a Staff Powertrain NVH Engineer to lead the noise, vibration, and harshness (NVH) refinement of their electric powertrains. This role involves hands-on testing, root cause analysis, and driving design improvements for electric motors, gearboxes, and related components. The engineer will collaborate with cross-functional teams and utilize advanced NVH analysis techniques to ensure high-quality customer experience.

What you'd actually do

  1. Lead powertrain NVH development across electric drive units, including electric motors, gearboxes, bearings, differentials, pumps, mechanical disconnect solenoids, housings, mounts, and vehicle integration.
  2. 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.
  3. Perform sound power measurements for motors, gearboxes, pumps, and complete drive units to support target setting, benchmarking, and design validation.
  4. 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
  5. 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.
