Acoustic Test Engineer II

Job Title:

Acoustic Test Engineer II

Duration: 12 months

Location: Redmond, WA (on-site - lab work, not remote eligible)

Client is seeking an acoustic test engineer to execute hands‑on acoustic measurements on wearable audio devices and document the results in our quality records system. The role involves running an established, documented test process on a calibrated acoustic measurement bench and producing traceable test reports within a regulated quality environment (e.g., medical‑device / ISO‑style design controls). There will be close collaboration with a senior engineer who owns the test requirements, calibration methodology, and quality standards.

Execution will be against those defined procedures.

• Familiarity with basic acoustic measurement signs, real‑ear insertion gain, ability to work with BNK hats, calibrators, high precision measurement microphones
• Ability to quickly set up equipment in labs for audio test, familiarity in working with quick chambers. Basic scripting comfort (Python and/or MATLAB) to operate measurement tools and run analysis scripts
• Basic signal processing, great reporting and communication skills

• Ability to troubleshoot measurement issues in complex test scenarios
• Ability to create new test set‑ups to improve processes. Experience in a regulated / quality‑controlled environment (e.g., FDA, ISO 13485, medical‑device design verification);
  Familiarity with an electronic quality management system (eQMS)
• Audiology / hearing‑device measurement background (real‑ear measurements, dynamic‑range compression, insertion gain)

• Execute acoustic test protocols on devices under test - including gain, output level, frequency response, and calibration measurements - precisely following procedures
• Set up and operate the measurement bench: head-and-torso simulators (HATS) / acoustic couplers, audio interfaces, acoustic calibrators, and device mounting/fitting
• Run the acoustic measurement software end‑to‑end: audio-device and channel configuration, microphone and speaker calibration, measurement capture, and data archiving
• Honor acceptance criteria and gating - flag out‑of‑tolerance results, calibration faults, and anomalies for review; never pass questionable data silently
• Produce and file traceable test reports in the team's quality records system: test identifiers, device serial numbers, calibration records, and raw + processed data
• Maintain meticulous lab records, equipment calibration status, and device logs
• Escalate measurement‑judgment and calibration questions to the supervising engineer

• 1-3 years of hands‑on acoustic/audio measurement or lab‑test experience: sound‑pressure‑level, frequency‑response, gain, and level measurements
• Willingness and aptitude to learn real‑ear / insertion‑gain measurement methods
• Comfort operating measurement hardware - audio interfaces, acoustic calibrators, acoustic test fixtures/couplers (or demonstrated ability to ramp quickly)
• Exceptional attention to detail and documentation discipline; able to follow written procedures precisely and reproducibly
• Basic scripting comfort (Python and/or MATLAB) to operate measurement tools and run analysis scripts
• Reliable, organized, and able to work independently within a structured process
• Comfortable on macOS or able to ramp quickly

• Audiology / hearing‑device measurement background (real‑ear measurements, dynamic‑range compression, insertion gain)
• Experience in a regulated / quality‑controlled environment (e.g., FDA, ISO 13485, medical‑device design verification)
• Familiarity with an electronic quality management system (eQMS)

Associate's or Bachelor's degree in acoustics, audio/electrical engineering, physics, audiology/hearing science, music/audio technology, biomedical engineering, or a related technical field — or equivalent hands‑on lab/test experience.
