Job Description

Position Details:
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

1. 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.
2.           Audio DSP Fundamentals
Must understand:

• Equalization
• Dynamic Range Compression (DRC)
• Limiting
• Speaker Protection

The candidate must understand what these functions do, how they work, how they are used, and the associated trade-offs.
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
