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
- End-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 org
- 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.
- 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).
AI Statement: By applying, you acknowledge that AI-assisted tools may be used during hiring.
