Job Title: Senior Audio Engineer
Job Location: Redmond, WA, USA, 98052
Work Model: Onsite
Shift: General Business Hours
Employment Type: Temporary
FT/PT: Full-Time
Estimated Duration (In months): 13
Min Hourly Rate($): 80.00
Max Hourly Rate($): 90.00
Must Have Skills/Attributes: Audio Analysis, Integration Experience
Experience Desired:
Prior experience performing audio systems render tuning for consumer electronics products (AR/VR glasses, hearables) (10+ yrs),
Understanding of render DSP tuning approaches (10+ yrs),
Music production / live sound backgrounds (10+ yrs)
Required Minimum Education: Bachelor’s Degree
**C2C is not available**
Job Description
Degree Required:
• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Acoustics Engineering, or a related technical discipline
Must-haves Skills:
• Micro-speaker / small-format experience. Hands-on work with micro-speakers and small, open-ear acoustic designs. Experience with large-format or music equipment (instrument amplification, studio gear, consumer loudspeakers) does not transfer.
• Render tuning on shipped products. Personal contribution to tuning for products that reached market, with the ability to walk through specific decisions.
• Solid, fast acoustics fundamentals. Confident reasoning on cavity effects on frequency response and driver resonance behavior — without long hesitation.
• Practical test experience. First-hand HATS/GRAS use, audio system testing, and speech quality evaluation.
• Render pipeline depth. EQ, DRC, limiters, and speaker protection
• Tuning-oriented over theoretical. Strong modeling skills are a plus, but the role's center of gravity is practical tuning and evaluation.
• Clear communication. Structured, concise answers; able to explain technical reasoning to cross-functional partners.
• Operates with limited guidance.
• 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.
Preferred Skills:
Strong signals we value
• 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
• 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).
Description:
We are looking for a contingent Audio Render Tuning Engineer to support Client research AR glasses audio program. This role focuses on render-path DSP tuning of the speaker system using Client 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
