• Integrate, test, characterize, and validate audio recording and MEMS microphone-processing technologies.
• Perform audio measurements and evaluate the performance of audio algorithms and systems across a variety of acoustic conditions.
• Perform audio tuning and system-level debugging using development and diagnostic tools.
• Configure and debug microphone signal paths, channel mapping, audio routing, and related system configurations.
• Design and execute controlled acoustic experiments using prototype and reference hardware.
• Collect and analyze audio recordings and measurement data using waveform, spectral, RMS, sound pressure level, noise, and other objective analysis techniques.
• Develop scripts and tools to automate audio data collection, processing, analysis, and results generation.
• Reproduce and troubleshoot audio-quality and system-level issues and collaborate with algorithm and systems engineers to identify and validate solutions.
• Document test procedures, configurations, results, and technical findings.

Minimum Qualifications:

• Bachelor's degree in Engineering, Information Systems, Computer Science, or related field.

Minimum Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Acoustics, Audio Engineering, or a related technical field.
• Coursework or project experience in acoustics, digital signal processing, audio engineering, or a related field.
• Fundamental understanding of acoustics and audio measurement concepts, including decibels (dB), sound pressure level (SPL), frequency, amplitude, calibration, and frequency-domain analysis.
• Understanding of digital signal processing fundamentals such as sampling, filtering, frequency-domain analysis, gain, noise, and dynamic range.
• Programming or scripting experience using Python, MATLAB, C/C++, or similar languages, including experience gained through coursework or academic projects.
• Ability to analyze technical data, troubleshoot problems, and communicate technical results clearly.
• Interest in hands-on laboratory work involving audio systems, microphones, measurement equipment, and prototype hardware.

Preferred Qualifications

• Academic, internship, research, or project experience involving audio signal processing, acoustics, embedded systems, or audio measurement.
• Familiarity with microphones, audio recording systems, or acoustic measurement techniques.
• Familiarity with mobile or embedded systems.
• Exposure to Android audio architecture, audio routing, or embedded audio systems.
• Experience using Python or MATLAB for signal analysis, visualization, or test automation.
• Experience with audio or acoustic laboratory equipment.
• Familiarity with development or diagnostic tools used to debug embedded systems.

Level of Responsibility:

• Works under supervision.

• Decision-making affects direct area of work and/or work group.

• Requires verbal and written communication skills to convey basic, routine factual information.

• Tasks require multiple steps which can be performed in various orders; some planning, problem-solving, and prioritization must occur to complete the tasks effectively.
