Job Description
Required Education:
•Bachelor degree in Electrical Engineering, Mechanical Engineering, Acoustics Engineering, or a related technical discipline
Required Skills:
•Years of overall experience required:10+ years
•Hands-on DSP tuning on a speaker-type device. This is the single most important requirement. Knowing about these algorithms or having tested them is not sufficient — the candidate must have personally performed
the tuning
•Audio DSP fundamentals. Must understand what equalization, dynamic range compression, limiting, and speaker protection do, how they function, how they are used, and what the trade-offs are
•Ability to apply and tune existing algorithms on an audio system (an audio systems engineer profile). Writing algorithms from scratch is not required
Preferred Skills:
•Direct AR/VR glasses or other head-worn audio device experience.
•Transducer-level characterization and speaker integration experience (T/S parameters, Klippel, impedance, excursion)
•Exposure to embedded audio middleware or firmware-level audio bring-up (Audio Weaver, Qualcomm QACT, ADSP integration)
Overview:
We are looking for a contingent Audio Render Tuning Engineer to support Client research AR glasses audio program. This role focuses on render-path DSP tuning of the speaker system using Client internally-developed embedded audio processing framework and tuning tools. The successful candidate will be hands-on in the lab working closely with the Research Audio team to deliver a tuned shipping-quality speaker experience
Required Qualifications:
•Prior experience performing audio systems render tuning for consumer electronics products (AR/VR glasses, hearables, headphones, wearables, telecom devices, smart speakers)
•Understanding of render DSP tuning approaches (EQ, DRC, limiting, speaker protection) and hands-on experience performing tuning in a lab environment
•Experience with electroacoustic measurement tools (e.g. Audio Precision (APx series), Listen SoundCheck, HEAD acoustics ACQUA) and measurement transducers
•Experience with MATLAB for audio signal processing, filter design, and tuning tool workflows
•Strong attention to detail and systematic approach to parameter optimization and documentation
•Ability to work independently on tuning tasks while collaborating with a broader audio engineering team
•Understanding of speaker protection algorithms (excursion limiting, thermal protection, brownout protection)
Preferred Qualifications:
•Experience with speaker integration and transducer-level characterization (T/S parameters, Klippel, impedance, excursion)
•Exposure to DSP frameworks or audio middleware (AudioWeaver, Qualcomm QACT, or similar embedded audio toolchains)
•Experience with volume table tuning and perceptual loudness optimization
•Exposure to firmware-level audio bring-up or ADSP integration workflows
•Experience with capture-path audio tuning including any of beamforming and spatial filtering, noise suppression, wind noise rejection, wake-word/keyword detection and speech recognition testing, capture-path gain staging and mic array calibration
Typical day to day in the role:
•Measure the glasses in an anechoic chamber or lab environment to collect raw performance data
•Work with the cross-functional team to define or receive performance targets
•Develop or tune existing software algorithms to adjust the audio output of the speakers, then re-measure and validate against those targets
•Split time between hands-on lab work and development work at the desk
•Set up and conduct subjective demos and listening tests with managers and leaders across the audio team and cross-functional teams
•Work with suppliers on troubleshooting — understanding trade-offs, diagnosing why performance falls short of expectations, and finding ways to extract additional performance
•Interface regularly with audio software engineers, mechanical engineers, audio hardware engineers, and vendor partners
Key Responsibilities:
•Render DSP Tuning: Perform speaker render-path tuning for research AR glasses using the company's internally-developed embedded audio DSP framework and associated MATLAB-based tuning tools
•Tuning Components: Design and apply equalization filters, tune dynamic range compression and limiter parameters to optimize loudness, dynamics, sound quality, and distortion across use cases (media, voice, speech) while preserving speaker integrity
•Speaker Characterization & Baseline Measurement: Measure devices to establish baseline performance, collect frequency response, distortion (THD), and impedance data in anechoic or controlled acoustic environments
•Tuning Profile Management: Generate, compile, and validate tuning profiles via Client internal tuning toolchain for deployment to device firmware
•Collaboration with Cross-Functional Teams: Work with hardware, firmware, algorithms, and research teams to align tuning with system-level requirements
•Documentation: Maintain tuning documentation, test reports, and configuration records for each tuning iteration and release candidate
Tool Onboarding: Ramp up on Client internal audio DSP ecosystem including graphical pipeline editors, render tuning tools, and device control utilities with support from internal tooling teams
