Staff Validation Engineer, Photonic Fabric
About The Position
Marvell's 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.
Requirements
- 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.
Nice To Haves
- 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.
Responsibilities
- 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.
Benefits
- employee stock purchase plan with a 2-year look back
- family support programs
- robust mental health resources
- recognition and service awards
