About the Job

Requirements

  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, Physics, Manufacturing Engineering, or a related technical field, with 7+ years of relevant experience in manufacturing automation, test automation, or industrial software development.
  • Experience supporting optical transceiver, silicon photonics, semiconductor, advanced packaging, or high-volume electronics manufacturing environments.
  • Strong software development experience using Python, C#, C++, LabVIEW, or similar languages for manufacturing automation and equipment integration.
  • Experience developing software interfaces for manufacturing equipment, automated test systems, robotics, motion control platforms, and production hardware.
  • Strong understanding of manufacturing automation architectures, industrial communication protocols, and equipment integration methodologies.
  • Hands-on experience with manufacturing data systems, database development, and production analytics using SQL, NoSQL, or equivalent technologies.
  • Experience implementing automated data collection, process monitoring, statistical process control (SPC), yield analysis, and reporting solutions.
  • Familiarity with manufacturing execution systems (MES), ERP systems, factory automation platforms, and production traceability requirements.
  • Experience with source code management and software lifecycle processes using GitHub, Bitbucket, SVN, or similar version control tools.
  • Strong understanding of software quality practices including validation, regression testing, release management, bug tracking, and change control.
  • Experience supporting new product introduction (NPI), manufacturing scale-up, and production ramp activities.
  • Understanding of quality systems, reliability requirements, and manufacturing compliance standards.
  • Strong analytical, troubleshooting, and problem-solving skills to identify opportunities for automation and operational improvement.
  • Ability to manage multiple projects and priorities in a fast-paced, rapidly scaling manufacturing environment.
  • Ability to work effectively across global engineering, manufacturing, quality, and operations teams.

Responsibilities

  • Develop and implement automation solutions for optical transceiver, silicon photonics, and advanced packaging manufacturing processes from prototype through high-volume production.
  • Design, develop, and maintain software applications, automation frameworks, and control systems used for manufacturing equipment, test stations, calibration systems, and process monitoring.
  • Integrate manufacturing equipment, optical test systems, robotics, motion control platforms, and factory automation tools using standard communication protocols and software interfaces.
  • Partner with manufacturing, process, and test engineering teams to automate manual production activities, improve cycle time, reduce operator dependency, and enhance process repeatability.
  • Develop automated workflows for data collection, traceability, process control, and production reporting across manufacturing operations.
  • Create and maintain software tools for manufacturing execution, equipment monitoring, yield analysis, statistical process control (SPC), and production performance tracking.
  • Lead automation efforts supporting new product introduction (NPI), ensuring manufacturing systems, test platforms, and process controls are production-ready at launch.
  • Collaborate with quality and engineering teams to implement automated validation, calibration, and qualification processes that improve product quality and manufacturing consistency.
  • Develop dashboards, reporting tools, and analytics solutions to provide visibility into manufacturing performance, equipment utilization, yield trends, and operational bottlenecks.
  • Ensure manufacturing automation software follows quality management system (QMS) requirements, including version control, change management, documentation, validation, and release procedures.
  • Support troubleshooting and root cause investigations related to manufacturing equipment, automation systems, test stations, and production software.
  • Drive continuous improvement initiatives focused on automation, factory digitization, throughput optimization, yield improvement, and cost reduction.
  • Collaborate with software engineers, IT teams, database architects, and manufacturing leaders to define scalable automation architectures for future manufacturing growth.
  • Generate technical documentation, operating procedures, validation plans, and training materials for manufacturing automation systems.

Desired Qualifications

  • Knowledge of optical manufacturing processes, transceiver assembly, silicon photonics production, automated optical alignment, calibration systems, or high-speed optical testing.
