About the role

Optical Manufacturing Test Engineer specializing in software automation, focusing on test automation and networking protocols to validate Layer 1/Layer 2 systems. Develop Python-based test frameworks, use IXIA traffic generators, and support NPI and volume manufacturing with collaboration across design, hardware, and manufacturing teams.

Responsibilities

  • Collaborate with design engineering and manufacturing teams to define and develop test software for high-volume manufacturing of high-end optical components.
  • End-to-end manufacturing test ownership: Ensure all modifications and upgrades to test and manufacturing software are under change control and follow established QMS requirements. This includes monitoring software revision control, bug tracking, tester updates, regression testing, test logs, etc.
  • Keep documentation and test specifications up to date. Use systematic processes for test cases, results and defect management.
  • Proficient in using version control systems like Github/Bitbucket
  • Perform functional, regression, and performance testing on Layer 1 and Layer 2 network systems. Validate hardware and software integration with optical interfaces and network switches. Configure and use traffic generators (e.g., IXIA) to simulate network environments and evaluate performance.
  • Develop, maintain, and execute automated test cases in Python.
  • Continuously improve test frameworks and methodologies.
  • Integrate test software with cloud monitoring and reporting tools
  • Collaborate with developers and hardware engineers to identify, reproduce, and resolve defects. Support troubleshooting and root cause analysis to resolve product issues.
  • Responsible for analyzing, defining, developing, and executing continuous improvement plans to achieve test yield, cycle time, throughput, and scrap reduction.
  • Collaborate with quality teams for the planning and execution of qualification testing.
  • Collaborate with design teams and process engineering to ensure design for manufacturing (DFM) and design for test (DFT) guidelines are met.
  • Generate comprehensive test reports for internal and external stakeholders.
  • Develop and implement troubleshooting guidelines and automated tools, templates, and data analysis for testers and products in manufacturing.
  • Collaborate with software engineers, IT and database architects to define better solutions to manage and analyze manufacturing test data.

Qualifications

  • Bachelor’s degree in Electrical Engineering, Industrial Engineering, Physics, Computer Science, or related field, plus 7 years hand-on experience in software testing and test automation of optical transceiver products including Silicon Photonics. Experiences in transceiver module tests at 400G, 800G, 1.6T, etc., are preferable.
