Job Description
Education
Bachelor's degree in acoustics, electrical engineering, audio, or a related field.
Preferred Qualifications
• Master's degree in a related field.
• Working understanding of acoustic simulation.
• Prior experience with wearables or consumer audio hardware.
Required Skills
• Acoustics and audio signal processing — demonstrated industry experience, including working knowledge of audio DSP fundamentals (filtering, spectral analysis, transfer functions, array processing).
• Hands-on mic / mic-array prototyping and measurement — building and testing physical prototypes, plus practical experience with electroacoustic measurement systems and lab practice (Audio Precision, Brüel & Kjær, anechoic chambers, HATS).
• Basics of Python or MATLAB — enough scripting fluency to acquire, analyze, and visualize measurement data. Deep software engineering is not required.
Preferred Skills
• Working understanding of acoustic simulation (explicitly a stretch, not a requirement).
• Background at a big tech company, headphone maker (e.g., Bose), or hearing-aid company.
• Exposure to comms, AI-assistant, hearing features, or spatial audio capture use cases.
Overview:
The Audio Experience Team is looking for an Audio Systems Engineer to prototype and evaluate microphone arrays for next-generation Reality Labs wearable devices. In this role you will build proof-of-concept arrays, validate them through electroacoustic measurements in the lab, and work across hardware and algorithm teams to make sure capture performance holds up across the full range of product use cases.
Job Responsibilities
• Design and integrate proof-of-concept mic-array prototypes for target device form factors, including mic placement, mechanical fixtures, and multichannel recording setups.
• Plan and execute electroacoustic measurements — frequency response, sensitivity, directivity, and acoustic transfer functions — in anechoic and HATS-based setups.
• Run acoustic simulations of device-on-head scenarios to guide design choices and predict array performance.
• Compare simulated and measured results, identify and explain discrepancies, and evaluate prototype arrays against target performance metrics.
• Develop Python/MATLAB tooling for data acquisition, analysis, and visualization.
• Document results and present findings to acoustics, hardware, algorithm, and product partners.
Minimum Qualifications
• 4–5+ years of industry experience in acoustics and audio signal processing.
• Hands-on experience building and testing microphone or mic-array prototypes.
• Experience with electroacoustic measurement systems and lab practice (e.g., Audio Precision, Brüel & Kjær, anechoic chambers, HATS).
• Working knowledge of audio DSP fundamentals: filtering, spectral analysis, transfer functions, and array processing.
• Basic working proficiency in Python and/or MATLAB.
