Required Education:

• Bachelor degree in Electrical Engineering, Mechanical Engineering, Acoustics Engineering, or a related technical discipline

Required Skills:

• Years of overall experience required:10+ years
• 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 performedthe 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:

• 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)

Overview:

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

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)

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 calibrationTypical day to day in the role:
• Measure the glasses in an anechoic chamber or lab environment to collect raw performance data
• Work with the cross-functional team to define or receive performance targets
• Develop or tune existing software algorithms to adjust the audio output of the speakers, then re-measure and validate against those targets
• Split time between hands-on lab work and development work at the desk
• Set up and conduct subjective demos and listening tests with managers and leaders across the audio team and cross-functional teams
• Work with suppliers on troubleshooting — understanding trade-offs, diagnosing why performance falls short of expectations, and finding ways to extract additional performance
• Interface regularly with audio software engineers, mechanical engineers, audio hardware engineers, and vendor partners

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 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 internal audio DSP ecosystem including graphical pipeline editors, render tuning tools, and device control utilities with support from internal tooling teams

• Only those lawfully authorized to work in the designated country associated with the position will be considered.
• Please note that all Position start dates and duration are estimates and may be reduced or lengthened based upon a client's business needs and requirements.
