Principal Acoustic Engineer

Principal Acoustic Engineer:
Passive Acoustics & Transducer Integration  As part of the Sonos team, you’ll collaborate with people of all styles, skill sets, and backgrounds to realize our vision while fostering a community where everyone feels included and empowered to do their best work.
What You Will Do   Passive Acoustic Architecture:
Lead the end‑to‑end concept, design, and optimization of passive acoustic elements including custom wave guides, horns, ports, slot‑loaded geometries, and enclosure acoustic boundaries.
Transducer Integration & Phase Plug Design:
Design, simulate, and validate high‑frequency driver assemblies and phase plugs. Ensure seamless acoustic coupling between transducers and wave guides to achieve optimal directivity, frequency response, and distortion characteristics.
Source Manipulation & Advanced Geometries:
Solve complex acoustic boundary challenges for traditional drivers, collinear designs, and asymmetric acoustic designs, applying advanced source manipulation techniques for compact, high‑performance systems.
Acoustic Simulation & Modeling:
Utilize advanced acoustic modeling tools (FEA/BEM) to optimize beamwidth, directivity, and overall acoustic performance before physical prototyping, then correlate simulation with actual devices.
Strategic Development:
Help elevate the team’s internal expertise in high‑frequency elements and wide‑bandwidth drivers and leverage/refine our internal automated waveguide design tools.
Cross‑Functional

Collaboration:

Work closely with audio systems engineers, mechanical engineers, industrial designers, and the broader audio team to integrate acoustic architectures into premium soundbars, All‑in‑One loudspeakers, and home theater products.
What You Will Need    Education :
Required – A Bachelor's degree of Engineering or Physics. Desired – A Masters Degree of Science/Engineering with an emphasis in audio and acoustics.
Experience : 12+ years of hands‑on experience in acoustic engineering, with a proven track record of shipping high‑volume consumer audio or premium professional audio products.
Passive Acoustic Expertise :
Deep theoretical and practical knowledge of waveguide theory, horn loading, boundary interactions, and port/enclosure design.
Transducer & HF Knowledge :
Strong foundation in transducer component design—specifically high‑frequency domes, voice coils, phase plug synthesis, and motor topologies.
Simulation Proficiency :
Advanced experience with acoustic simulation and multi‑physics software (e.g., COMSOL) focusing on coupled transducer‑waveguide domains.
Measurement & Validation :
Extensive experience with acoustic measurement systems (e.g., Klippel, Audio Precision, Sound Check) and rapid prototyping techniques (3D printing, CNC).
Problem Solving : A strategic mindset with the ability to identify team knowledge gaps and autonomously drive complex, ambiguous design challenges from concept to mass production.
