Job Description:

We are looking for an Acoustics Engineer who will directly responsible for evaluation, test and optimization, and validation of voice and audio based portable consumer devices. Responsibilities include objective and subjective audio algorithm evaluation and validation, data analysis and competitive benchmarking. This role works hand in hand with Engineering Design and Manufacturing Teams.

Preferred Skills:

Job requirements

  1. Develop, optimize and debug acoustic products for the consumer market
  2. Define test programs for support of engineering prototyping and debug for research in acoustics
  3. Apply acoustic analytical techniques in order to determine noise suppression/cancellation results and adequacy to meet regulatory/specified requirements.
  4. Improving lab test capabilities by specifying and acquiring new test equipment and/or test methods, documenting test procedures, and correlating various acoustic test lab results.
  5. Define, design and debug associated hardware platforms for support of engineering prototypes and demonstrations.
  6. Perform objective and subjective audio algorithm evaluation and validation, data analysis and competitive benchmarking.
  7. Applying robust acoustic analytical techniques to optimize the signal processing results and determine adequacy to meet regulatory and specific customer requirements.
  8. Participate in reviews of designs, implementations, or documentation prepared by others or self.
  9. As required, work and coordinate with vendors to develop microphones, earpiece receivers, and micro-loudspeakers for use in mobile handsets.
