Principal Acoustic Engineer - Passive Acoustic Design

Sonos, Inc.; Hilversum; Hybrid; EUR 94,000 - 117,000; Full time

Job summary

Sonos, Inc. is seeking a Principal Acoustic Engineer to lead the design and integration of passive acoustics and transducer systems for our next-generation audio products.

You will bridge acoustic simulation, loudspeaker design, and physical transducer development, owning the passive acoustic domain and enclosure integration. You will work with audio and mechanical teams to deliver premium soundbars and AiOs, optimize waveguides, phase plugs, and high-frequency drivers, and translate simulations

Qualifications

• Bachelor's degree in Engineering, Physics, or related field.
• 7+ years of acoustic engineering experience with consumer or premium audio products.
• Deep knowledge of waveguide theory, horn loading, boundary interactions, and enclosure design.
• Strong foundation in transducer components—high-frequency domes, voice coils, phase plug synthesis, motor topologies.
• Advanced experience with acoustic simulation and multi-physics software (e.g., COMSOL).
• Experience with acoustic measurement systems (Klippel, Audio Precision, SoundCheck) and rapid prototyping (3D printing, CNC).

Responsibilities

• Lead end-to-end concept, design, and optimization of passive acoustic elements (waveguides, horns, ports, enclosure boundaries).
• Design, simulate, and validate high-frequency driver assemblies and phase plugs for optimal directivity and frequency response.
• Solve complex acoustic boundary challenges for traditional and collinear/novel driver designs.
• Utilize acoustic modeling tools to optimize beamwidth, directivity, and overall performance before prototyping.
• Collaborate with audio systems, mechanical, and industrial design teams to integrate acoustics into premium products.
• Refine internal waveguide design tools and contribute to mass production readiness.
