Test Methodology Development: Design and implement rigorous test plans and procedures for characterizing loudspeakers, microphones, and complete acoustic systems. Ensure compliance with international audio standards (e.g., IEC 60268, EN 50332, ITU-T).
Advanced Feature Validation: Lead the objective and subjective evaluation of advanced audio algorithms, including feedforward/feedback ANC, transparency modes, voice call quality (AEC/noise suppression), and wind noise reduction.
Automation & Tooling: Drive the development of scalable, automated audio test frameworks using Python, MATLAB, or LabVIEW to streamline regression testing and continuous integration (CI) pipelines.
Cross-Functional Collaboration: Serve as the primary technical representative for audio validation in leadership reviews. Partner with acoustic, mechanical, and electrical engineers to root-cause hardware failures, mitigate acoustic artifacts (e.g., rub and buzz), and optimize acoustic seals.
Factory Support: Support contract manufacturers (CMs) during early builds. Transfer validation test limits and methodologies to factory production lines to ensure consistent manufacturing quality.
Required Qualifications
Education: Bachelor’s or Master’s degree in Electrical Engineering, Acoustics, Physics, Computer Engineering, or a closely related field.
Experience: 6-9 years of hands-on experience in audio hardware testing, acoustic measurement, or audio systems engineering, with at least 2+ years in a technical leadership or management role.
Domain Expertise: Deep understanding of electroacoustics, transducer design principles (microphones and micro-speakers), and audio signal processing fundamentals. Proven track record of shipping high-volume consumer audio electronics, specifically wearable or hearable devices.
Laboratory Proficiency: Extensive hands-on experience setting up and operating acoustic test environments, including anechoic chambers, isolation booths, and specialized audio measurement equipment.
Automation Skills: Strong programming and scripting skills (Python, MATLAB, C++) for automating test equipment and analyzing large datasets.
Analytical Skills: Exceptional problem-solving abilities with a data-driven approach to root-cause analysis and statistical process control.
