Acoustic Test Engineer

Location : US - WA - Redmond

Job Title : Test Engineer

• Engagement: Contingent worker, full-time, on-site (lab work -- not remote-eligible)

Job Description: Acoustic Test Engineer

Role summary

Meta 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.

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 Logistics
