Job Title: Senior Audio Hardware Engineer Location: Thane, MH About the Role: Namaskaram! We are looking for a highly skilled Audio Hardware Engineer to join our team and design and develop advanced audio systems for our next-generation products. In this role, you will be responsible for architecting and implementing high-performance audio hardware subsystemsfrom microphones and speakers to amplifiers and audio codecs. Key Responsibilities: Design, prototype, and validate analog and digital audio circuits, including microphone arrays, speaker drivers, amplifiers, and codecs. Schematic design, PCB layout reviews, and bring-up of audio hardware. Conduct in-depth analysis and optimization of audio quality, including signal integrity, noise reduction, echo cancellation, and distortion control. Evaluate and select audio components (MEMS mics, DACs/ADCs, amps, etc.) based on performance, cost, and power consumption. Own the hardware validation and test plan for audio systems using test equipment such as Audio Precision, oscilloscopes, and spectrum analyzers. Work closely with manufacturing partners to resolve issues related to audio hardware during prototyping and mass production. Required Qualifications: Bachelors or Masters degree in Electrical Engineering, Electronics, or a related field. 5+ years of hands-on experience in audio hardware design and development. Proven experience with audio signal path design, including both analog and digital domains. Proficiency with schematic capture and PCB layout tools (e.g., Altium Designer, Cadence). Experience with electroacoustic testing, tuning, and validation. Strong understanding of audio performance metrics (THD+N, SNR, latency, etc.). Familiarity with EMI/EMC mitigation techniques and low-noise analog design. Experience working on consumer electronics, wearables, or AR/VR products is a strong plus. Nice to Have: Experience with beamforming, active noise cancellation (ANC), or echo cancellation (AEC). Understanding of Bluetooth audio (A2DP, BLE Audio) and relevant audio transmission standards. Familiarity with voice assistants and wake-word detection architectures. Experience collaborating with DSP and algorithm teams.,
