AOI
Overview
Applied Optoelectronics, Inc. (AOI) is seeking a Production Test Engineer with strong experience in Python and LabVIEW automation to develop, maintain, and optimize automated test systems for high-speed optical transceivers and components (200G/400G/800G). This role involves designing test automation software, integrating optical/electronic instruments (OSA, power meters, BER testers, DCAs, TEC controllers, etc.), and supporting manufacturing teams to ensure reliable and efficient production testing. Job Duties
Design, develop, and maintain automated test software using Python and LabVIEW for optical transceiver module and component testing. Integrate and control instruments such as Optical Spectrum Analyzers (OSA), power meters, source meters, BER testers, oscilloscopes (DCA), and TEC controllers using VISA, GPIB, RS-232, TCP/IP, and PXI interfaces. Develop, debug and modify existing/new LabVIEW programs to match local test setups, hardware, and environmental conditions. Support manufacturing engineers in troubleshooting production line test failures and improving test yield and reliability. Conduct system-level debugging for optical, electrical, and thermal test setups. Create and maintain SOPs, training documents, and provide hands-on training to operators and technicians on new test procedures and UIs. Collaborate with cross-functional teams (R&D, QA, PE, IT) to align test requirements and automation standards. Maintain revision control and documentation of all test programs and configurations. 5% international travel may be required for station deployment, training, or cross-site alignment. Perform other duties as assigned. Job Requirements
Required:
Bachelor\'s degree in Electrical Engineering, Optical Engineering, Computer Engineering, or a related discipline. Preferred:
Master\'s degree in Electrical or Computer Engineering 1 – 3 years of experience in LabVIEW programming and/or Python test automation Experience with test instrumentation (OSA, power meters, source meters, TEC controllers, oscilloscopes, etc.). Understanding of data acquisition fundamentals (plug-in data acquisition cards, RS-232, GPIB, PXI devices and signal conditioning of various sensors). Strong teamwork and communication skills to manage multiple/concurrent projects. Ability to work independently and take full responsibility. Lift or move items weighing up to 35 pounds. Bilingual in Chinese (Mandarin) is a plus. Location
This position will be on-site based in Sugar Land, Texas. Why AOI?
In addition to a competitive salary, AOI offers: Flexible and competitive health plans (medical, dental, vision) with options to meet individual and family needs Employer matching on 401(k) deferrals Generous PTO policy, with unused PTO payout at end of the year Relocation package available within the US Immigration sponsorships (Must be currently authorized to work in the US) We do not accept unsolicited proposals from third-party recruiters or agencies. Contacting hiring managers directly may result in disqualification of submissions.
