Job Description
Duration: 12 months
Description: Role Summary
We are looking for a contingent Audio Render Tuning Engineer to support client's research AR glasses audio program. This role focuses on render-path DSP tuning of the speaker system using Client's 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.
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's 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's internal audio DSP ecosystem including graphical pipeline editors, render tuning tools, and device control utilities with support from internal tooling teams
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)
- Bachelor's degree in Electrical Engineering, Mechanical Engineering, Acoustics Engineering, or a related technical discipline
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
- Target Industries (stack-ranked)
- AR/VR glasses — top preference
- Hearables and headphones (earbuds, over-ear headphones)
- Wearables (watches or other worn devices with audio features)
- Telecom devices (mobile phones)
- Smart speakers (Alexa, Google Home, and similar)
