About The Position

As an NVH Engineer, you'll be the guardian of peace and quiet in our customers' homes, ensuring our robots operate so they practically disappear into the background of daily life. You'll apply deep acoustic expertise across mechanical, electrical, and software systems to achieve industry-leading noise performance. If you're passionate about the science of sound and obsessed with creating products that are quieter than a whisper, we'd love to talk to you about how you can help us set new standards for home robotics.

Requirements

Technical degree in Mechanical Engineering, Acoustics, or Physics
4+ years of experience in NVH engineering for consumer products, automotive, or appliances
Expertise with acoustic measurement equipment including sound level meters, intensity probes, and accelerometers
Proficiency in NVH analysis software such as LMS Test.Lab, Brüel & Kjær PULSE, or HEAD acoustics ArtemiS
Experience with acoustic simulation tools including COMSOL, Actran, or VA One
Strong understanding of acoustics fundamentals including wave propagation, modal analysis, and psychoacoustics
Knowledge of vibration isolation principles, damping mechanisms, and acoustic material properties
Experience with Design of Experiments (DOE) for systematic noise reduction studies
Familiarity with acoustic standards (ISO 3744, IEC 60704) and sound quality metrics (loudness, sharpness, roughness)
Track record of achieving aggressive noise targets in shipped consumer products
Comfort with fast-paced, startup atmosphere -- you don't shy away from the hard work
High level of maturity, ownership, and pride in your work

Responsibilities

Lead system-level acoustic optimization to achieve industry-leading noise levels of 50-55 dBA during operation
Conduct comprehensive NVH testing including sound power measurements, modal analysis, and psychoacoustic evaluation
Perform root cause analysis of noise sources using techniques like sound intensity mapping, ODS, and transfer path analysis
Design acoustic treatments including damping materials, isolation mounts, and absorption strategies
Develop and validate acoustic simulation models using SEA, BEM, or FEM methods for early-stage design optimization
Create NVH specifications and cascade requirements to subsystem teams for motors, fans, gears, and structural components
Optimize airflow paths and fan designs to minimize aeroacoustic noise while maintaining thermal performance
Design vibration isolation systems and tuned mass dampers to reduce structure-borne noise transmission
Establish and operate acoustic testing facilities including semi-anechoic chambers and reverberation rooms
Work with industrial design team to integrate acoustic solutions without compromising aesthetics or usability
