About the Job

Requirements

  • Bachelor’s or Master’s degree in Mechanical Engineering or a related field.
  • 10+ years of experience in powertrain NVH, with demonstrated ownership of electric drive unit NVH development.
  • Strong hands-on background in NVH testing, including sound power, transfer path analysis, frequency response functions, modal analysis, and vehicle-level diagnostics.
  • Demonstrated ability to lead NVH development programs, not just execute tests.
  • Deep understanding of electric motor NVH, including permanent magnet synchronous motor 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 ability to correlate customer perception with objective engineering data.
  • Proficiency with Testlab, Artemis, MATLAB, and Python.
  • Experience with rubber isolation systems and powertrain mounts and their impact on vehicle NVH performance.
  • Ability to install and remove sensors and powertrain hardware, manipulate test setups, support vehicle and dynamometer testing, handle test equipment and components, work in confined or industrial spaces, and stand or move for extended periods during testing.

Responsibilities

  • 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 laboratory and on-road environments, focusing 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 and traditional transfer path analysis methods to quantify source strengths from motors, gears, bearings, pumps, and disconnect mechanisms, and identify dominant NVH paths into the vehicle.
  • Generate diagnostics using frequency response functions, modal analysis, and operating deflection shape 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 and induction motors, electromagnetic excitation, torque ripple, 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.
  • Plan and conduct NVH tests to correlate and validate computer-aided engineering models, enabling predictive powertrain NVH development and robust design decisions.
  • Partner with design, controls, computer-aided engineering, manufacturing, and vehicle integration teams to implement NVH-driven design changes efficiently and pragmatically.
  • Translate NVH data into technical reports and recommendations for engineering leadership and cross-functional stakeholders.
  • Develop and standardize NVH test procedures, data processing workflows, and automation tools to improve efficiency, repeatability, and scalability across programs.
  • Contribute to continuous improvement initiatives within the NVH organization.

Desired Qualifications

  • An advanced degree is preferred.

About the Company

Rivian

Makes electric pickups, SUVs and delivery vans

Rivian designs and builds electric pickup trucks, SUVs, and delivery vans, pairing off-road ability with electronics and software it develops itself. In 2021, its R1T became the first fully electric pickup truck on the US consumer market, ahead of larger rivals such as Ford and Tesla. It makes the R1T pickup, the R1S and R2 SUVs, and commercial vans in Normal, Illinois, and sells them directly online and in its own stores rather than through dealers. Its vehicles run on Rivian's own software, which gains features through updates sent over the internet, and most revenue comes from vehicle sales, with service and optional software adding more. Rivian was founded in 2009 and is based in Irvine, California.
