Audio Render Experience Engineer

Overview

Join our team as a Render Experience Engineer, where you will be instrumental in refining audio render systems for diverse product variants developed from a reference design. Your expertise will be crucial in operating our render tuning toolchain, ensuring optimized audio performance across all proliferation products. You will play a vital role in both objective and subjective evaluations, leveraging your technical acumen to maintain and advance high-quality render experiences.

Responsibilities

• Conduct detailed acoustic measurements on speaker systems using tools like HATS, SoundCheck, and Audio Precision to assess parameters like frequency response, distortion, and power characterization.
• Execute complex render tuning workflows, including EQ design, speaker protection, and distortion control, within company-provided toolchains.
• Run comprehensive power simulations to verify compliance with power budgets across various operating conditions.
• Carry out objective and subjective verification protocols, promptly reporting any deviations from defined KPI acceptance criteria within 24 hours.
• Adjust tuning parameters based on KPI assessments and subjective evaluations to optimize audio performance.
• Assess the acoustic impact of industrial design-driven mechanical changes on render performance, including speaker cavity and port placement.
• Create and validate measurement data in support of structured programs with tight timelines, generating standardized performance reports for manufacturing handoff.
• Troubleshoot render pipeline issues and escalate software-related problems to the appropriate engineering teams.

Minimum Qualifications

• Bachelor’s degree in Electrical Engineering, Acoustics, Physics, or a related field, or equivalent professional experience.
• Over 3 years of experience with acoustic measurement systems such as HATS, Audio Precision, and Listen SoundCheck, including work with anechoic chambers.
• Proficiency in MATLAB and/or Python for acoustic data processing and analysis.
• Experience in tuning render system algorithms for consumer electronics, with a focus on critical listening and subjective evaluation.
• Solid understanding of electroacoustic principles, including speaker Thiele-Small parameters and frequency response interpretation.
• Knowledge of DSP fundamentals, such as biquad filters and frequency domain analysis.
• Strong lab discipline, including adherence to SOPs and thorough documentation practices.
• Excellent communication skills with experience in reporting technical findings to engineering stakeholders.

Preferred Qualifications

• Familiarity with AI tools and agentic workflows to enhance tuning processes.
• Master’s degree in Electrical Engineering, Acoustics, or a related discipline.
• Previous experience with wearable or open-ear speaker systems.
• Expertise in render system models or simulation-based design, including COMSOL acoustic simulations.
• Understanding of ADB and Android audio stack nuances.
• Insight into speaker protection algorithms and distortion control methods, such as multi-band DRC.
• Familiarity with telecommunication audio standards and VoIP quality metrics.
• Experience with laser displacement measurements and Klippel speaker measurement tools, ideal for advancing consumer electronics NPI cycles.
