Job Summary:

xMEMS is at the heart of edge AI, redefining what's possible in sound reproduction and thermal management with the world's most innovative piezoMEMS platform. Founded in 2018 and headquartered in Santa Clara, CA, we've built a portfolio of 300+ patents and brought the world's first solid-state MEMS speakers and micro-cooling chips to market. Our PulseAir MEMS speakers are powering the next wave of AI wearables—from smart glasses to earbuds—while our µCooling technology is solving critical thermal challenges not only in edge AI devices like smartphones and AR glasses, but also in datacenter infrastructure including high-performance SSDs and optical transceivers. Backed by $21M+ in Series D funding, we're at the intersection of silicon innovation and the global AI buildout, scaling fast and looking for exceptional people to help tell our story.

We are seeking a Senior Application Engineer to support customer integration, platform development, and performance optimization of advanced xMEMS MEMS 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.

Key Responsibilities:

• Provide direct engineering support to key customers, ODM/CM partners, and Field Applications Engineers during design-in, validation, and commercialization
• Develop 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
• Lead 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, 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
• 7+ years of experience in the electronics industry, preferably with mixed-signal audio amplifier, power, or related hardware background
• Strong customer-facing experience with excellent verbal and written communication skills
• Hands-on experience with component selection, schematic entry, and PCB layout design concepts; Cadence or Altium preferred
• Strong lab experience using oscilloscopes, spectrum analyzers, signal generators, logic analyzers, and related bench equipment
• Audio system test experience using platforms such as Audio Precision, SoundCheck, or equivalent
• Strong 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
• Strong ability to collaborate with mechanical, DSP, acoustic, and third-party engineering teams
  

Location:

• This position will be based in Santa Clara, CA.
