Our client is a global leader in e-commerce, cloud computing, and digital innovation, serving millions worldwide. Known for a customer-obsessed approach and advanced technology, they continue to redefine how people shop and access services. Their focus on scalability, efficiency, and innovation keeps them at the forefront of multiple industries.

We are seeking a multilingual technical professional for an initial 3-month onsite assignment in San Jose, with potential for a long-term extension based on fit and business need. This hands-on role supports automotive audio and speech systems, embedded digital signal processing (DSP), acoustic measurement, vehicle and audio-lab test-bench readiness, software build updates, and data collection across multiple South Bay Area lab sites.

The selected candidate will use Korean, Mandarin Chinese, or Japanese, along with English, to localize single- and multi-turn voice-assistant tests, review speech recordings, and document validation results. Based on performance and fit, the scope may expand into real-time DSP algorithm work, QNX Sound or Hexagon aDSP/cDSP firmware development, and ownership of acoustic measurement and calibration programs.

• Operate automotive hardware test benches and audio-lab equipment in hands-on lab and garage environments.
• Execute and localize single- and multi-turn voice-assistant test cases using native-speaker-quality pronunciation and accent.
• Review large audio-recording sets in Adobe Audition or Audacity and perform basic editing and signal processing, including normalization, for test-automation pipelines.
• Support QNX Sound stack issues and automotive hardware lab maintenance, including audio-subsystem firmware updates and test-equipment calibration.
• Collect vehicle data in laboratory and on-road driving conditions.
• Maintain vehicle fleet readiness through basic upkeep, inspections, and readiness checks.
• Support engineers with vehicle software updates, build changes, and firmware flashing.
• Build, wire, and maintain test rigs, cabling, and related lab infrastructure.
• Use mechanical and electrical tools, including screwdrivers, multimeters, soldering irons, and crimpers, to bring up, repair, and modify equipment.
• Work directly with circuit boards, single-board computers such as Raspberry Pi, development boards, switches, routers, and network cabling.
• Log and track defects in JIRA or a similar system with clear severity, priority, and reproduction steps.
• Prepare clear status and validation reports for the required audience using provided templates.
• Coordinate work across multiple South Bay Area lab sites and drive vehicles between locations as needed.
• Learn unfamiliar hardware and software quickly and take on new technical challenges.

You combine audio, speech, or embedded DSP experience with a working knowledge of acoustics and fluency in English and Korean, Mandarin Chinese, or Japanese. You can conduct conversational voice testing with native-speaker-quality pronunciation and work confidently with audio-lab equipment, vehicle test benches, circuit boards, and embedded hardware in a multi-site environment.

• Fluency in spoken and written English and Korean, Mandarin Chinese, or Japanese.
• Bachelor's degree in Electrical Engineering, Computer Engineering, or a signal-processing-related field, or equivalent hands-on experience.
• At least 1 year of experience with audio, speech, or embedded DSP work, or demonstrated competence through digital signal processing coursework or projects.
• Working knowledge of audio and acoustics fundamentals, including acoustic measurement, microphones, transducers, and speech and audio signal behavior.
• Ability to operate audio-lab equipment and automotive hardware test benches and work hands-on in a lab or garage environment.
• Ability to run single- and multi-turn voice test cases with native-speaker-quality pronunciation and accent.
• Ability to review, edit, and normalize large audio-recording sets using Adobe Audition, Audacity, or comparable audio tools.
• Comfort supporting QNX Sound architecture and maintaining automotive hardware labs, including firmware updates and…
