- Lead NVH development of drive units, belt systems, and complete vehicles from concept through production.
- Develop and validate CAE models for drive units and vehicle systems, including modal, forced response, transfer function, and sensitivity analyses.
- Correlate simulation results with laboratory and vehicle measurements using techniques such as MAC and Transfer Path Analysis (TPA).
- Moderate experience conducting vehicle-, component-, and dynamometer-level NVH testing to identify source, path, and receiver contributions.
- Simulate/measure transfer functions, source characterization, and transfer path analyses to identify dominant noise and vibration mechanisms.
- Define NVH targets, metrics, and acceptance criteria for drive units, belt systems, road noise, wind noise, accessories, and structural vibration.
- Recommend design improvements for motors, gears, housings, bearings, belts, mounts, and isolation systems.
- Collaborate with controls engineers to reduce NVH through software optimization, including motor control angle optimization, harmonic current injection, PWM switching strategies, and related techniques.
- Correlate electromagnetic, structural, and acoustic behavior to improve overall system performance.
- Some experience instrumenting vehicles and laboratory test setups using accelerometers, microphones, laser vibrometers, tachometers, thermocouples, strain gauges, current probes, impact hammers, and shakers.

- We’re ALSO, an electric mobility company originally conceived as a part of Rivian. We’re a passionate team of builders, dreamers, doers and innovators, focused on creating entirely new (not to mention, innovative and delightful) vertically integrated, small EVs designed to meet the global mobility challenges of today and tomorrow. Our mission is to inspire everyone to ride ALSO—replacing many local car, truck and SUV miles with ones on vehicles that are more affordable, more enjoyable and 10-50x more efficient.
- ALSO is seeking a Senior NVH Engineer to join our Drive Unit Team. In this role, you will lead the development, simulation, and validation of NVH performance for drive units and vehicles. You will combine CAE, laboratory testing, and vehicle validation to identify noise and vibration issues, develop countermeasures, and influence product design from concept through production. Working closely with design, controls, electromagnetic, manufacturing, and attribute teams, you will reduce NVH error states while balancing cost, mass, efficiency, and product complexity across multiple vehicle programs.
- Strong understanding of vibration, structural dynamics, rotational acoustics, and psychoacoustic metrics including loudness, sharpness, articulation index, prominence ratio, tone-to-noise ratio, and spectral weighting.
- Moderate experience with NVH testing software such as Siemens Simcenter Testlab, Head Acoustics, Artemis, or equivalent.
- Strong experience with NVH simulation tools such as Simcenter 3D, Abaqus, Ansys, Nastran, or equivalent.
- Experience correlating CAE models with experimental measurements using MAC, modal testing, and Transfer Path Analysis.
- Hands-on experience performing vehicle, component, dynamometer, modal, and source-level NVH testing.
- Experience using controls development tools such as CANape, CANalyzer, or similar.
- Proficiency in MATLAB and/or Python for data analysis, automation, and simulation support.
- Understanding of electric motor NVH, including electromagnetic excitation, stator mounting, rotor skew, pole count, cogging torque, and harmonic excitation.
- Familiarity with gear, bearing, and belt system NVH, including common excitation mechanisms and mitigation techniques.
- Knowledge of vibration isolation, damping treatments, acoustic materials, and mount design.
- Experience performing sensitivity studies, Monte Carlo analyses, and design optimization.
- Excellent communication skills with the ability to present complex technical information clearly to engineers and leadership.
- The salary for this position ranges from $180,000 - $210,000 depending on experience, location, and qualifications. This role will be based out of Palo Alto, CA.
- We’re passionate about helping the world find a better way to get there—wherever it is you’re headed.
- We’re located in the heart of Silicon Valley and have brought together a world-class team from some of the biggest brands in the technology, automotive, cycling, outdoor recreation and retail spaces.
- Together we’re working hands-on to imagine, design and build an entirely new solution to a global set of transportation challenges.
