Sound, speech capture, and acoustic performance are essential facets of this user experience across AirPods, Beats, iPhone, Mac, iPad, and Apple Vision Pro. The Instrumentation Systems Engineering Group plays a key role in upholding Apple’s quality standards, and through your work with the team, you will have the unique opportunity to impact products all across Apple.\nWe are looking for a Senior Audio & Acoustic Instrumentation Systems Engineer to serve as the Station DRI and technical lead for the development, validation, and deployment of calibration and test equipment for Apple’s manufacturing lines. You will work closely with Acoustic Engineering, Validation, Mechanical Design, and Operations teams throughout the New Product Introduction (NPI) phase and into mass production to ensure the success of current and future Apple products.\nDescription\nYou will brainstorm, design, simulate, and develop instrumentation systems used to calibrate and test Apple’s groundbreaking technologies and products. Your design work will range from lab-scale measurement prototypes-requiring a deep first-principles understanding of acoustic physics and product architecture-to developing automated mass-production test stations, where balancing engineering tradeoffs between accuracy, precision, cost, lead-time, and throughput is critical.\nWith the diversity of the problem space, you will rely on your acoustic and systems engineering background to architect optimal metrology solutions, leaning on physical fundamentals to solve complex hardware and signal-processing challenges. You will work collaboratively with a creative and diverse team of experienced engineers across mechanical system design, core audio technology, product design, and global manufacturing partners to deliver state-of-the-art measurement systems for Apple.\nMinimum Qualifications\nDeep familiarity with physical acoustics, room/chamber acoustics, electroacoustics, and transducer fundamentals (microphones, speakers, receivers).\nHands-on experience with acoustic and vibro-acoustic multiphysics simulation (COMSOL, ANSYS) for cavity acoustics, boundary reflections, and structural isolation.\nSolid understanding of audio DSP, transfer function calibration, and acoustic measurement instrumentation (e.g., Audio Precision, SoundCheck, B&K, GRAS couplers, laser vibrometry).\nExperience with 3D CAD tools (preferably NX/UG) to review and guide mechanical test fixture, sealing, and acoustic chamber architectures.\nStrong programming and data analysis skills in one or more of the following: Python, MATLAB, C/C++, or JMP.\nExcellent written and verbal communication skills in both English and Mandarin to collaborate across global engineering teams and manufacturing partners.\nPhD or MS in Acoustics, Electroacoustics, Mechanical Engineering, or a related field with a dedicated focus in acoustics.\n1+ years (PhD) or 3+ years (MS) of professional experience in acoustic instrumentation, audio test engineering, or metrology system design.\nPreferred Qualifications\nProven track record as a Station DRI or Technical Lead in high-volume consumer electronics manufacturing across NPI phases (Proto, EVT, DVT, PVT, MP).\nExperience designing scalable instrumentation, HW/SW test automation, and working directly with contract manufacturers (CMs) and system integrators.\nExperience with acoustic materials specification (absorbers, dampers, barriers, and sealing elastomers) for test enclosures and fixtures.\nAdvanced knowledge of acoustic array signal processing (beamforming, TDOA) and non-linear distortion diagnostics.","description_format":"text","description_chars":3727,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All
