Job Description
Job DescriptionPosition SummaryxMEMS 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
