Acoustic Test Engineer

Core Engineering - Test Engineer II

Title:

Acoustic Test Engineer

Role summary:
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.

Responsibilities:

• 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

Required qualifications:

• 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

Preferred:

• 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)

Education:

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
