The Technology Engineering for Devices organization brings together world-class experts to develop and ship groundbreaking products at the intersection of hardware, software, and content. We operate on aggressive, fixed timelines to ship products at scale. Our products define new categories that advance Meta's mission to give people the power to build community and bring the world closer together. We seek an Audio Systems Engineer to join our Audio Experience Team. We expect you to be experienced in defining, tuning, and evaluating audio capture systems and solutions, including microphone array architectures, electroacoustics, and signal processing, and apply your acquired skills and growth mindset in productization of cutting edge smart glasses and AR/VR audio experiences.

Audio Systems Engineer Responsibilities

• Analyze, define, tune, and debug real-time audio capture systems for forward looking products and user experiences


• Identify and implement new technologies and techniques to improve microphone array performance


• Learn constantly, dive into new areas with unfamiliar technologies and define key performance indicators (KPIs) for novel user experience targets


• Define capture system architecture, algorithms, and tools with developers and coordinate their implementation


• Evaluate and benchmark performance of third party audio capture algorithms and stay up-to-date on industry trends and advancements in microphone array technology


• Maintain familiarity with various DSP platforms and the trade-offs of embedded implementations


• Collaborate with cross-functional teams to drive innovative solutions for microphone array architectures across our smart glasses and AR/VR HW programs

Minimum Qualifications

• 4+ years experience defining, tuning, and testing efficient microphone-array processing and real-time audio capture algorithms


• 4+ years of experience defining, prototyping, and demonstrating compelling audio experiences with end-to-end audio systems including acoustics, transducers, digital interfaces, audio ICs, and DSPs


• 4+ years experience designing and deploying objective test methodologies for consumer electronics devices and audio algorithms or features such as voice communication, voice assistant, video capture


• 4+ years experience with audio test systems such as SoundCheck, Audio Precision, or HEAD Acoustics ACQUA and knowledge of telecommunications standards


• Familiarity with typical DSP building blocks such as digital biquad filters, IIR, FIR, AGC, wide-band/multi-band DRC, and audio capture algorithms such as beamforming, echo cancellation, and noise suppression.


• Experience operating independently, communicating effectively, and driving audio workstreams in a dynamic cross functional environment, from product concept to mass production


• Working knowledge with a high-level programming language such as MATLAB, Python


• B.Sc. degree in EE, Computer Science, Acoustics, or equivalent experience

Preferred Qualifications

• Experience with psycho-acoustic metrics for speech quality and intelligibility


• Familiarity with human perception of spatial sound


• Experience with perceptual audio quality evaluation methods, designing and deploying subjective tests for audio systems


• Familiarity with audio rendering algorithms and loudspeaker technologies


• Experience in acoustics and consumer audio EE architecture


• Familiarity with audio algorithm development, machine learning techniques, and/or neural network implementation


• Familiarity with acoustic simulation software, e.g. COMSOL


• M.Sc. or Ph.D. in EE, Computer Science, Acoustics, or related disciplines
