The ideal candidate for the Audio Tuning and Testing Engineer position should have 2-5 years of experience and be proactive in joining our audio engineering team. In this role, you will be responsible for tuning, validating, and optimizing audio systems in various products such as TWS earbuds, smart speakers, tablets, and voice-enabled devices. We are seeking engineers with strong lab skills, hardware insight, and a genuine passion for sound quality. Your key responsibilities will include conducting audio validation and tuning using tools like Sound Check, Audio Precision, B&K, Crysound, or their equivalents. You will be tasked with optimizing speaker, microphone, and ANC performance, as well as performing tests according to standards like TIA, ITU, and IEEE for audio. Additionally, you will review hardware schematics to suggest audio design improvements and analyze analog/digital audio signals such as waveforms, SNR, and THD. Supporting root cause analysis for hardware, firmware, and system-level issues will also be part of your responsibilities. Moreover, you will work on audio algorithms like EC/NS, ANC, AGC, ICC, SRC, and speech enhancement, while maintaining test procedures, tuning logs, and certification data. The required skills for this role include a solid understanding of analog/digital audio signal chains, experience with probing, debugging, and lab-based signal analysis, familiarity with digital interfaces like I2S, I2C, SPI, and Slimbus, the ability to read schematics and comprehend PCB-level audio paths, hands-on experience with tools like Sound Check, APx, or B&K, troubleshooting skills across hardware, firmware, and software layers, proficiency in Python or MATLAB scripting for automation and analysis, and an understanding of Bluetooth audio (A2DP, HFP), Android HAL, or COMSOL (optional). It would be nice to have experience in VoIP, telephony, or mobile audio, exposure to ANC tuning, EC/NS, limiter, ICC, or SRC, familiarity with Android audio KPIs and certification processes, and a basic understanding of speech recognition and enhancement. Candidates for this position should hold a B.E./B.Tech degree in ECE, EEE, E&I, Audio Engineering, or a related field. In addition to technical skills, soft skills such as clear written and verbal communication, good team collaboration and interpersonal skills, the ability to multitask and adapt in a fast-paced environment, and problem-solving skills with attention to detail are essential.
