Audio Engineer V(ID: 73271-1)
Location: Redmond, WA
Duration:12+ months (high extension possibility)
Pay Range: Negotiable based on experience.
Audio Render Tuning Engineer (Meta Research AR Glasses Audio Program)
Role Summary:We are looking for a contingent Audio Render Tuning Engineer to support Meta's research AR glasses audio program. This role focuses on render-path DSP tuning of the speaker system using Meta'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 Meta'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 Meta'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
Candidate Requirements:
Must-Have Skills
- Hands-on DSP Tuning on a Speaker-Type Device
Knowing about these algorithms or having tested them is not sufficient. The candidate must have personally performed the tuning.
2. Audio DSP Fundamentals
Must understand:
- Equalization
- Dynamic Range Compression (DRC)
- Limiting
- Speaker Protection
3. Ability to Apply and Tune Existing Algorithms on an Audio System
This is an audio systems engineer profile.
Writing algorithms from scratch is not required.
Nice-to-Have Skills:
1. Direct AR/VR Glasses or Other Head-Worn Audio Device Experience
2. Transducer-Level Characterization and Speaker Integration Experience
Including: T/S Parameters, Klippel, Impedance, Excursion
3. Exposure to Embedded Audio Middleware or Firmware-Level Audio Bring-Up
Including: Audio Weaver, Qualcomm QACT, ADSP Integration
Experience Requirements:
- Overall Experience: 10+ years
- Education: Bachelor's degree in Electrical Engineering, Mechanical Engineering, Acoustics Engineering, or a related technical discipline
Interview Process:
Number of Interview Rounds:2 to 3 rounds
Round 1: Initial Screen with CWAM:General questions, Behavioral questions, Candidate assessment and fit evaluation
Round 2: Technical Panel:In-depth signal processing discussion, Cross-functional collaboration assessment
Interview Duration:45 minutes to 1 hour per round
Resume Review Timeline:2 to 3 days
