Staff Acoustic Hardware Engineer

• Lead acoustic and audio hardware development across the full product lifecycle, from concept and architecture through design, validation, production launch, sustaining, and end-of-life.
• Define, design, and optimize audio and acoustic architectures, including microphones, speakers, amplifiers, codecs, and associated audio signal paths.
• Perform acoustic characterization, testing, tuning, and performance optimization at the component, subsystem, and product levels.
• Drive hardware development and integration across audio, battery and charging, power management, sensors, touchscreen, processors, memory, and related subsystems.
• Provide technical leadership to JDM engineering teams, including board-level design, implementation, integration, debugging, schematic review, component selection, PCB layout, and design documentation.
• Develop comprehensive hardware and acoustic requirements, specifications, interface definitions, validation criteria, and verification and validation plans.
• Lead prototype bring-up, system characterization, debugging, and root-cause analysis of complex acoustic, electrical, and system-level issues.
• Characterize and optimize overall system performance across audio quality, power consumption, battery life, thermal performance, reliability, and manufacturability.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Acoustical Engineering, or a related engineering field, with 6+ years of relevant product development experience.
• Proven experience developing handheld, mobile, wireless, or battery-powered electronic products, including full hardware development, integration, validation, and manufacturing support.
• Strong expertise in audio and acoustic system architecture, design, integration, characterization, and optimization, including microphones, speakers, amplifiers, codecs, audio interfaces, and signal paths.
• Hands-on experience with acoustic measurement, testing, tuning, debugging, and product-level audio optimization using appropriate audio and acoustic measurement equipment.
• Strong hardware design experience across battery and charging technologies, power management, low-power design, embedded processors, memory, sensors, touchscreen technologies, and high- and low-speed digital interfaces.
• Knowledge of ARM or x86 processor architectures and low-power memory architectures, with proven ability to design, review, bring up, and debug complex circuit boards and system-level hardware issues.

Preferred Qualifications:

• Experience reviewing and directing multi-layer PCB designs, including fine-pitch BGAs, sensitive analog/audio circuitry, high-speed signals, power distribution, signal integrity, EMI/EMC, thermal management, reliability, and manufacturability.
• Proven hands-on debugging and validation experience using oscilloscopes, logic analyzers, spectrum analyzers, and acoustic/audio measurement equipment, including prototype bring-up, functional verification, system integration, root-cause analysis, and manufacturing support. undefinedundefined
