Core Engineering - Test Engineer II
An opportunity is available for an Acoustic Test Engineer to execute hands-on acoustic measurements on wearable audio devices and document the results. This role involves running an established, documented test process on a calibrated acoustic measurement bench and producing traceable test reports within a regulated quality environment. This position involves close collaboration with a senior engineer who owns the test requirements, calibration methodology, and quality standards.
Key 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.
- Produce and file traceable test reports in the quality records system, including test identifiers, device serial numbers, calibration records, and raw and processed data.
- Maintain meticulous lab records, equipment calibration status, and device logs.
- Escalate measurement-judgment and calibration questions to the supervising engineer.
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.
Experience:
1-3 years of hands-on acoustic/audio measurement or lab-test experience, including sound-pressure-level, frequency-response, gain, and level measurements. Willingness and aptitude to learn real-ear/insertion-gain measurement methods.
Technical
Skills:
Basic scripting comfort (Python and/or MATLAB) to operate measurement tools and run analysis scripts. Comfort operating measurement hardware such as audio interfaces, acoustic calibrators, and acoustic test fixtures/couplers. Ability to work with macOS is required.
- 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).
