Your Team Your Impact

Marvells Photonics Fabric group is pioneering the next generation of optical interconnect technology for AI infrastructure. The team develops cutting-edge silicon photonics and co-packaged optics solutions designed to overcome the bandwidth and power limitations of traditional electrical interconnects enabling the massive data movement demands of large-scale AI accelerators and data center fabrics.
This posting is for the Electrical Integrated Circuits team within the group focused on the design of high-speed optical SerDes the analog and mixed-signal circuits at the heart of the photonics fabric. Engineers on this team work at the intersection of advanced IC design high-speed signaling and photonic systems solving some of the hardest electrical-optical interface challenges in the industry.

What You Can Expect

• Build and own Python automation for SerDes PIC validation: instrument control (PyVISA / SCPI) test sequencing calibration routines and end-to-end measurement flows.
• Develop reusable libraries and frameworks for scopes BERTs VNAs tunable lasers optical power meters and DCAs so the same code scales across devices channels and link configurations.
• Support bench-level validation of SerDes Tx/Rx operating through a PIC: eye quality jitter equalization (CTLE / DFE / FFE) CDR and Rx BER / link margin.
• Characterize PIC devices in the live link: EAM / MZM OMA extinction ratio (ER) TDECQ modulator bandwidth photodetector responsivity and Rx sensitivity.
• Help build and run integrated electro-optical test setups (probe stations DCAs BERTs tunable lasers optical power meters fiber fixtures); assist with fiber handling and alignment.
• Correlate component-level PIC data (e.g. DCA spot-checks of EAMs and PDs) with full SerDes-driven link performance.
• Execute validation test plans across PVT corners and per-channel coverage
• Contribute to shared validation infrastructure: version-controlled code code reviews and documentation.

What Were Looking For

• M.S. in EE Optical Engineering Computer Engineering or related field (strong B.S. also considered).
• 3 years of relevant industry experience.
• Experience writing test automation or measurement scripts that drive lab instruments (PyVISA / SCPI or equivalent). Comfort with Git and collaborative workflows (branches PRs).
• Exposure to SerDes measurement concepts: eye / jitter BER equalization link margin.
• Hands-on time with lab instrumentation (scopes BERTs VNAs or power meters) from coursework internships or research.
• Coursework or project exposure to photonics optoelectronics or high-speed digital / SI.
• Clear written communication; able to work on-site in Santa Clara CA.

• Hands-on exposure to electro-optical validation (PICs silicon photonics optical transceivers or CPO).
• Familiarity with TDECQ OMA ER Rx sensitivity or DCA-based optical eye / BER measurements.
