  • Design acoustic fixtures based on customer requirements.

  • Develop and Debug test solutions for Microphone prototypes.
  • Troubleshooting design / technical issues as they arise.
  • Leads validation testing planning and execution of MEMS Microphone.
  • Defining and analyzing design verification results to ensure product is meeting requirements.
  • Help identify and innovate new or iterative products through collaboration with subject matter experts.
  • Create circuit models using both lumped parameter and finite element analysis. Then use these models to determine the best ASIC, MEMS, and Package components to meet the design requirements.
  • Perform failure analysis on microphone prototypes.
  • Lab testing and characterization of microphone and ASICs.
  • Evaluating ASIC and other subcomponents in the lab to validate system performance.
  • Work closely with other design and test engineers to test, and characterize designs at every stage.
  • Occasionally assist Application Engineering with technical support escalations that require deeper subject matter expertise.
  • Closely work with test and design engineers across various business units.
  • Help achieve design concepts that meet or exceed internal specification and/or customer requirements.

  • Experience designing, building, and debugging electronic systems using digital oscilloscopes, power supplies, parameter analyzer, data acquisition and other standard small signal electrical lab equipment
  • Experience in lab testing of circuits while working with design team
  • Some experience with National Instruments LabVIEW is preferable
  • Knowledge of acoustic concepts especially lumped element equivalent circuits for acoustic systems and transducers is good to have.
  • Knowledge of FEA software such as COMSOL Multiphysics and/or Ansys is good to have.
  • Knowledge of analog and/or digital audio systems: microphones (MEMS, ASIC), speakers, audio formats, audio signal chain in modern consumer electronics is a plus
  • Experience with lumped parameter modeling in SPICE, Modelica, or other software is preferred.
  • Experience with making lab measurements in the frequency and time domain using equipment like spectrum analyzers, audio analyzers, and oscilloscopes is strongly preferred.
  • Experience working with cross-functional and remote engineering teams is essential.
  • Excellent spoken and written communication skills in English.
