Job Title: Core Engineering - Test Engineer II
Job Description: 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 (nice to have)
- 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
