NVH Engineer

Company Overview

Each year, 2.5 trillion hours are spent on household chores. At Matic, we’re on a mission to recapture that lost time, and we’re doing it by revolutionizing home robotics.

Our first product, also called Matic, is a Wall-E-esque floor cleaning robot. We've built what amounts to "full self-driving in the home” with real-time 3D mapping, adaptive path-tracking, and a precise semantic understanding of the home. Our breakthroughs in spatial AI allow Matic to work reliably in real homes, using only RGB cameras and neural networks running on-device.

Privacy First

What happens in the home, stays in the home. Our robots are private by design, with all data processing performed by the robot itself, not in the cloud.

Our Approach

Before the iPhone, consumers adopted several distinct devices; cell phones, PDAs, and portable music players each served a particular need. We believe in a similar progression for home robotics, starting with single-purpose robots and building iteratively toward more complex capabilities over time.

Our Culture

Matic is a tight-knit and collaborative team, singularly focused on building products our customers will cherish. We're ultra-hardworking people committed to solving tough problems that save precious time and energy.

About the role

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.

What you'll do

• 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

What we look for

• 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

We'd love to hear from you if...

• You are genuinely motivated to help those around you

• You are passionate about learning outside of your normal comfort zones

• You love diagnosing complex technical issues

• You are excited to do great work
