Job Title: Acoustic Test Engineer II
Duration: 12 months
Location: Redmond, WA (on-site (lab work -- not remote-eligible))
Role summary:
- 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.
Must-Have Skills:
- 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 equipments 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
Nice-to-have 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
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.
Key Projects/Day-to-Day Responsibilities:
- Wearables group, overlap with conversation focus
- involve audio equipment set up
- lab measurements
- reporting
- audio trouble shooting, diagnostics
- adhering to strict standards to devices that could be medical devices.
- Expand testing capabilities with guidance from senior engineers
How will performance be measured:
- Precision of measurements and quality of the testing, consistency in test results and timely fashion
- open to learn and expand testing capabilities and knowledge
What makes this role interesting:
- Work on cutting edge speech enhancement technology on wearables with high focus on acoustic testing methodology through an innovative lens
Interview Process:
- How many rounds of interviews: 2 rounds
- Types of Interviews: Questions on general knowledge, audio and acoustic, audio signal processing, basic scripting in python and matlab
- Interview Duration: 45 minutes
