Job description
Senior Principal Engineer, Software/Firmware - Coherent Optical Module Firmware / SoC-based Embedded Platforms / CPO
Onsite
Engineering / Architecture
ctMarvell's Optics firmware team develops the software that powers the next generation of optical interconnects — from high-volume Data Center Interconnect (DCI) coherent modules (400ZR, 800ZR/ZR+) deployed at hyperscale cloud providers, to emerging Co-Packaged Optics (CPO) platforms that will redefine how compute and optical I/O are integrated at the rack level. Our products are at the heart of the industry's transition to higher-bandwidth, lower-power optical connectivity, and our firmware is a key differentiator in winning and retaining the world's most demanding customers. You'll join a team of experienced engineers who have shipped multiple generations of coherent module platforms and are now building the foundation for what comes nex
