Test Engineer II

Job Title: Acoustic Test Engineer (Test Engineer II)

Duration: 12 Months (Potential for Extension)

Location: Redmond, WA (Onsite 5 Days/Week)

We are seeking a detail-oriented Acoustic Test Engineer to join an innovative engineering team focused on testing next-generation wearable audio devices. This is a hands-on laboratory role where you will perform acoustic measurements, execute standardized test procedures, and document results within a quality-controlled environment.

You will work closely with senior engineers to ensure accurate testing, maintain equipment calibration, and contribute to the validation of advanced audio technologies.

• Execute acoustic test protocols for wearable audio devices, including:
  • Gain measurements
  • Output level testing
  • Frequency response analysis
  • Calibration verification
• Set up and operate acoustic measurement equipment, including:
  • Head and Torso Simulators (HATS)
  • Acoustic couplers
  • Audio interfaces
  • Acoustic calibrators
  • Device fixtures and mounting hardware
• Configure and operate acoustic measurement software for:
  • Device configuration
  • Channel setup
  • Microphone and speaker calibration
  • Measurement capture
  • Data archiving
• Review measurement results against acceptance criteria and identify any anomalies or calibration issues.
• Generate detailed, traceable test reports and maintain accurate quality records.
• Maintain laboratory equipment, calibration records, and testing documentation.
• Escalate technical or calibration-related concerns to senior engineering staff.
• Support continuous improvement of laboratory testing processes.

• 1 3 years of hands-on experience in acoustic testing, audio measurements, or laboratory testing.
• Experience performing:
  • Sound Pressure Level (SPL) measurements
  • Frequency response testing
  • Gain and level measurements
• Familiarity with acoustic measurement hardware and laboratory equipment.
• Strong attention to detail with excellent documentation skills.
• Basic scripting experience using Python and/or MATLAB.
• Ability to follow standardized procedures with high accuracy.
• Comfortable working independently within structured engineering processes.
• Experience using macOS or willingness to learn.

• Experience with:
  • Real-ear measurements
  • Insertion gain
  • Hearing devices or audiology testing
• Experience working in regulated or quality-controlled environments (e.g., medical devices or ISO-compliant processes).
• Familiarity with Electronic Quality Management Systems (eQMS).
• Experience troubleshooting acoustic measurement issues and improving laboratory test setups.

Associate's or Bachelor's degree in one of the following or a related technical discipline:

• Acoustics
• Audio Engineering
• Electrical Engineering
• Physics
• Biomedical Engineering
• Audiology / Hearing Science
• Music or Audio Technology

Equivalent hands-on laboratory testing experience will also be considered.

The ideal candidate is passionate about audio technology, enjoys hands-on laboratory work, and has a meticulous approach to testing and documentation. This opportunity offers exposure to cutting-edge wearable technologies while working alongside experienced engineers in a highly collaborative environment.
