Electrical Engineer

Responsibilities

• Optimize acoustic performance for TWS earbuds and audio products, including speaker units, acoustic chambers, and sound tubes.
• Tune acoustic metrics such as frequency response, distortion, and sensitivity to ensure high sound quality.
• Review and optimize audio processing algorithms including Active Noise Cancellation (ANC), Equalizer (EQ), and Acoustic Echo Cancellation (AEC).
• Debug Bluetooth audio protocols (A2DP, HFP, LC3) to ensure low-latency, high-fidelity transmission.
• Conduct comprehensive acoustic testing using professional equipment such as KEMAR, artificial ears, and APx audio analyzers.
• Develop and execute test plans, analyze data, and provide actionable feedback to ODM partners.
• Collaborate with cross-functional teams, including product management, quality assurance, and mechanical engineering, to align acoustic structures with industrial design.
• Document test procedures, results, and tuning recommendations in detailed technical reports.

Requirements

• Bachelor's degree or higher in Acoustics, Electrical Engineering, Signal Processing, Physics, or a related field.
• Minimum 5 years of experience in acoustic design or audio product development, preferably with TWS earbuds.
• Strong foundation in acoustic theory, including sound wave propagation, impedance matching, and resonance.
• Proficiency with acoustic testing equipment (KEMAR, B&K microphones, APx audio analyzers) and audio analysis software (SoundCheck, CLIO).
• Expertise in Digital Signal Processing (DSP) and audio algorithms (ANC, EQ, AEC).
• Knowledge of Bluetooth audio protocols (A2DP, HFP, LC3) and their impact on latency and bandwidth.
• Programming skills in Python or MATLAB for data analysis and algorithm development.

Preferred Qualifications

• Experience with spatial audio or low-power design projects.
• Familiarity with psychoacoustics and human auditory characteristics.
• Prior experience with patent drafting or technical publications.
