About MarvellMarvell’s semiconductor solutions are the essential building blocks of the data infrastructure that connects our world. Across enterprise, cloud and AI, and carrier architectures, our innovative technology is enabling new possibilities.At Marvell, you can affect the arc of individual lives, lift the trajectory of entire industries, and fuel the transformative potential of tomorrow. For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead.This is an existing vacancy.Your Team, Your Impact Marvell's Advanced Technology team is seeking a Principal SI/PI Engineer to provide silicon‑level technical leadership for high‑speed wireline and optical interface designs, including SerDes, die‑to‑die, optical DSP interfaces, and electrical‑to‑optical interconnects. This role focuses on on‑die signal and power integrity, from architecture through silicon validation, and influences next‑generation Marvell wireline and optical platforms.What You Can Expect

Serve as silicon SI/PI technical authority across wireline and optical interface IP and SoCs.
Define on‑die channel and power delivery architectures for high‑speed IO and optical interfaces.
Influence SerDes and IO specifications, including jitter/noise budgets, equalization strategy, and PI targets.

Signal Integrity (Silicon Focus)

Lead SI analysis for NRZ and PAM4 SerDes (56G/112G/224G+).
Perform channel modeling, S‑parameter analysis, eye/jitter/BER analysis, and sensitivity to on‑die parasitics.
Work closely with analog/mixed‑signal designers to optimize TX/RX architectures and robustness.

Optical & Electro‑Optical Interfaces

Drive SI for electrical interfaces into optical systems, including optical DSP IO and modulator drivers.
Analyze jitter and noise transfer from electrical SerDes into optical modulation.
Correlate electrical SI metrics with optical link margin and performance.

Power Integrity

Architect and analyze on‑die and near‑die PDN for high‑speed interfaces.
Define impedance targets and mitigate SSN, supply‑induced jitter, and noise coupling.
Drive PI‑aware IO and floorplanning decisions.

Silicon Bring‑Up & Methodology

Correlate simulations with silicon measurements (eye, jitter, noise).
Support first‑silicon bring‑up, debug, and root‑cause analysis.
Establish SI/PI sign‑off criteria and best practices across design teams.

What We're Looking For

MS or PhD in Electrical Engineering or related field.
10+ years of experience in SI/PI for high‑speed silicon wireline interfaces.
Deep expertise in high‑speed SerDes architectures, including NRZ and PAM4 signaling, jitter decomposition, and noise analysis.
Strong power integrity background, including:

On‑die and near‑die PDN architecture
Impedance target definition and frequency‑domain analysis
Simultaneous switching noise (SSN) and supply‑induced jitter mitigation
Supply noise coupling into sensitive SerDes and optical interface circuits
Proven experience with on‑die channel modeling and S‑parameter analysis.
Experience analyzing electrical interfaces for optical systems (optical DSP IO, modulator drivers, or electro‑optic interfaces).
Hands‑on experience with industry tools such as Cadence Sigrity, Keysight ADS / SIPro, and Ansys HFSS (or equivalent).
Strong understanding of CMOS mixed‑signal design, high‑speed IO circuits, and silicon‑level noise coupling mechanisms.
Demonstrated ability to lead technically across silicon design teams and influence architecture and sign‑off decisions.
