Position Summary

xMEMS Labs is redefining sound and cooling with its breakthrough piezoMEMS platform. We created the world's first solid-state MEMS speakers — powering AI glasses, earbuds, headphones, and smartwatches — and the first µCooling fan-on-a-chip, enabling improved thermal performance in smartphones, AI glasses, SSDs, and beyond.

We are seeking an Application Engineer to support customer integration, platform development, and performance optimization of advanced Piezo-MEMS micro speaker audio solutions. This role bridges hardware platform design, R&D collaboration, and customer-facing technical support, helping enable successful design-in and commercialization across next-generation audio wearable products. The position involves both hands-on lab work and direct engagement with customers and field application teams.

We weigh hands-on ability and engineering fundamentals more heavily than years on a résumé. Experienced audio and mixed-signal engineers will find substantial ownership here, and strong early-career engineers — including recent Master's graduates in Electrical Engineering — are encouraged to apply. Scope and title are calibrated to the person we find.

Key Responsibilities

• Provide direct engineering support to key customers, ODM/CM partners, and Field Applications Engineers during design-in, validation, and commercialization
• Develop and support xMEMS hardware platforms, including schematic design, PCB design, and firmware development
• Characterize, validate, and debug electrical and acoustic system performance
• Perform electrical assembly, soldering, and bring-up of demo and evaluation systems
• Support acoustic system tuning and performance optimization for micro speaker modules and related audio platforms
• Conduct lab measurements and validation, including SPL, THD, frequency response, and electrical signal integrity
• Troubleshoot field and customer issues, perform root cause analysis, and drive issue resolution across hardware and system levels
• Collaborate closely with IC design engineers to define design requirements based on customer use cases and system needs
• Work cross-functionally with mechanical, DSP, acoustic, product, and test engineers to support product development and customer deployment
• Develop technical collateral including datasheets, application notes, integration guides, reference designs, and technical articles
• Support technical communication with customers through clear verbal, written, and specification-level documentation

Required Qualifications

• Bachelor's degree in Electrical Engineering, Acoustics, Physics, or related field; Master or higher degree welcome
• 1+ years of experience in the electronics industry, preferably with mixed-signal audio amplifier, power, or related hardware background — recent Master's graduates with strong fundamentals and substantial hands-on project, research, or internship experience will also be considered
• Interest in and aptitude for customer-facing work, with clear verbal and written communication skills
• Hands-on experience with component selection, schematic entry, and PCB layout design concepts; Cadence or Altium preferred
• Lab experience using oscilloscopes, spectrum analyzers, signal generators, logic analyzers, and related bench equipment
• Working knowledge of acoustic fundamentals, transducers, and audio system performance validation
• Experience debugging electrical and acoustic hardware issues in a hands-on development environment
• Ability to read, write, and work from detailed technical specifications
• Ability to collaborate with mechanical, DSP, acoustic, and third-party engineering teams

Preferred Qualifications

• Audio system test experience using platforms such as Audio Precision, SoundCheck, or equivalent
• Experience supporting consumer audio products such as TWS, wired earbuds, OWS, gaming headsets, VR/AR devices, AI glasses, OTC hearing devices, or other wearables
• DSP and audio tuning experience
• Tier 1 customer support experience
• Firmware bring-up experience on existing reference designs
• Scripting for test automation and data analysis (Python or MATLAB)
• Mandarin language ability, given close collaboration with our Taiwan team and Asia-based ODM/CM partners

Key Success Traits

• Customer-facing confidence and technical credibility, or the clear potential to develop it
• Hands-on hardware and lab debugging capability
• Ability to translate customer problems into practical engineering solutions
• Strong ownership and problem-solving ability, including scoping, planning, and driving investigations
• Curiosity and willingness to learn quickly in a fast-moving hardware environment
• Comfortable balancing detailed lab work with external technical communication

Location / Practical Requirements

• Santa Clara, California, USA
• Bachelor's degree required
• Ability to commute to the job location required
• Occasional travel to customer and ODM/CM sites, including Asia, may be required
