Job description

We are seeking an Electro-Acoustic Engineer to work with our dynamic product development team. Industry experience in miniature electro-acoustic and mechanical components is desired. We seek a person who will assist in the development of new designs through proof of concept and prototypes. Detailed modification or iterations of existing designs will also be required. The successful candidate will be expected to achieve exceptional results through his/her contribution to product introduction, and innovation. This individual will work closely with Senior and Principal Engineers on design and technology concepts that are aligned with customer needs and business goals.

Key Responsibilities

• Design and development of microphone system using MEMS, ASIC and PCB.
• Engage closely in multiple development phases through proof-of-concept / prototypes to mass production.
• 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.

Qualification and Skills

• Bachelor’s Degree (Master’s or Doctorate preferred) in Electrical, or Mechanical Engineering, Material Science, Acoustics, or Physics
• Minimum of 5-7 years’ experience in developing electro-mechanical, electro-acoustic products
• Experience and knowledge of hearing aids, audio or acoustic product development is strongly preferred.
• 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.
