In an increasingly connected world, the pandemic has highlighted just how essential telecom networks are to keeping society running. The Network Infrastructure group is at the heart of a revolution to connectivity, pushing the boundaries to deliver more and faster network capacity to people worldwide through our ambition, innovation, and technical expertise
Join Optical Networks division, where innovation meets scale in the AI-driven data center era. With the recent acquisition of Infinera, we’ve united two industry leaders to create an optical networking powerhouse—combining cutting-edge technology with proven leadership to redefine the future of connectivity.
The successful candidate shall possess the capability to design and analyze high-speed, high-performance analog/mixed-signal circuits, including data converters, PLLs, and SERDES, in advanced CMOS FinFET technologies. She or he shall bring the design to production. Engaging in high-speed analog circuit design gives you the chance to create the technical differentiation that will allow Infinera to hold market leadership. By building cutting-edge circuitry, we will together revolutionize the era of efficient high-speed transmission.- Design, implement, and simulate the functionality and performance of various high speed analog circuits, including the ADCs and DACs;
