• Background working on audio devices, audio hardware, or within the audio industry (headphones, speakers, earbuds, audio interfaces, professional audio equipment, etc.).
• Ability to read and parse technical documentation (schematics, firmware specs, audio subsystem datasheets) and convert to test logic.
• Hands-on experience running and debugging code across multiple software environments and test suites.
• Foundational understanding of audio signal chain concepts - ADCs, DACs, codecs, amplifiers, clocking, digital audio interfaces (IS, PDM, TDM).
• Exposure to scripted test development - writing, executing, and maintaining test cases for hardware or firmware validation.

Responsibilities

• Read and interpret audio system technical documentation and translate requirements directly into executable test scripts.
• Handle on-demand requests for new and evolving audio test requirements with fast code turnaround.
• Develop, run, and debug test code across multiple scripting languages(Python, Lua, and others) within various software suites
• Maintain and extend automation and sequence engine frameworks for audio validation and diagnostics

• Working ability to translate requirements into code - Python, Lua, or similar scripting languages
• Background working on audio devices, audio hardware, or within the audio industry (headphones, speakers, earbuds, audio interfaces, professional audio equipment, etc.)
• Ability to read and parse technical documentation (schematics, firmware specs, audio subsystem datasheets) and convert to test logic
• Hands-on experience running and debugging code across multiple software environments and test suites
• Foundational understanding of audio signal chain concepts - ADCs, DACs, codecs, amplifiers, clocking, digital audio interfaces (IS, PDM, TDM)
• Exposure to scripted test development - writing, executing, and maintaining test cases for hardware or firmware validation

Preferred Skills

• Familiarity with automation or sequence engines used in hardware/firmware test workflows
• Prior experience with unit te sting frameworks (pytest, unittest, or equivalent)
• Exposure to audio measurement tools - Audio Precision APx, HEAD acoustics, Klippel, or GRAS
• Knowledge of audio protocols and codecs - IS, SoundWire, USB Audio, AAC, LC3, Bluetooth HFP/A2DP
• Experience in NPI or manufacturing test environments (EVT/DVT/PVT build cycles, EOL/ATE testing)
• Familiarity with DSP concepts - filtering, EQ, ANC, beamforming, noise floor characterization
