Electro-Optical Digital Test Development Engineer

Essential Functions / Key Responsibilities

• Participate in the software, hardware, and test plan development for calibrating and measuring performance of Infinera’s Digital Coherent Optical (DCO) modules, operating at 400-1200 GBps per wave, based on Photonics Integrated Circuits (PIC)s
• Define and configure required test instrumentation and hardware
• Partner with product team to author, debug, and refine novel, efficient optical calibration sequences
• Co-develop with firmware, DSP teams on feature introduction
• Develop software to fully automate the test execution
• Partner with engineering staff to define and implement detailed testability requirements
• Provide fault isolation and identification capability to the design and manufacturing technical staff
• Help drive end to end test yield improvements and test time reduction efforts

Education / Experience

• BS in science or engineering required, MS or PhD desired (Physics, Optics, Electrical Eng)
• Previous experience in developing test and measurement solutions for electrical and optical components or subsystems is beneficial

Knowledge / Skills / Abilities

• Proficient in writing scalable software a requirement.
• Experience with object-oriented languages required. VB.Net exposure is a plus.
• Familiarity with quadrature amplitude modulation theory is a requirement; modern DSP knowledge including soft decision FEC is helpful.
