Duration: 12 monthsRole 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 toolsTuning Components: Design and apply equalization filters, tune energetic range compression and limiter parameters to optimize loudness, dynamics, sound quality, and distortion across use cases (media, voice, speech) while preserving speaker integritySpeaker Characterization & Baseline Measurement: Measure devices to establish baseline performance, collect frequency response, distortion (THD), and impedance data in anechoic or controlled acoustic environmentsTuning Profile Management: Generate, compile, and validate tuning profiles via client's internal tuning toolchain for deployment to device firmwareCollaboration with Cross-Functional Teams: Work with hardware, firmware, algorithms, and research teams to align tuning with system-level requirementsDocumentation: Maintain tuning documentation, test reports, and configuration records for each tuning iteration and release candidateTool 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 teamsStrong signals we valueEnd-to-end ownership of an audio feature (modeling through evaluation); a balance of structured listening and objective measurement (frequency response, THD, distortion, compression,



attack/release); comfort in a matrixed orgMust haveHands-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.Nice to HaveDirect 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).
