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)
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
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
