About Marvell

Marvell’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. 

Your Team, Your Impact

The Center of Excellence (COE), part of the Custom Compute and Storage (CCS) Business Unit within Marvell's Data Center Group, is chartered to define, develop, and maintain standard, production-ready IP subsystems — spanning PCIe/CXL, Ethernet, DDR/Memory, Security/Boot, Low-Speed IO, and other critical technologies — that customers and internal SoC teams can adopt with confidence. By shifting left, the COE enables faster time-to-market, reduces integration risk, and ensures compliance, interoperability, and high performance across Marvell's SoC products. It embodies the "One Marvell" principle — sharing reusable components, verification environments, and knowledge across all business units to drive first-pass-right silicon. As part of the COE, you will design, verify, and deliver IP subsystem building blocks powering Marvell's most advanced custom chips for hyperscale cloud, AI, and data center customers — working at the intersection of architecture, RTL design, verification, firmware/software, and silicon validation.

What You Can Expect

• Develop and execute verification plans for high-speed memory interfaces (PCIE 6/7, CXL 3.2/4.0)

• Build and enhance UVM/System Verilog-based verification environments

• Develop test benches, sequences, and checkers for functional and performance validation

• Perform protocol-level verification for PCIE controllers and PHY interfaces

• Analyze and debug simulation failures, identify root causes, and drive resolution

• Work closely with design, architecture, and firmware teams to ensure coverage closure and spec compliance

• Contribute to coverage-driven verification (CDV) including functional, code, and assertion coverage

• Support emulation/FPGA validation and post-silicon bring-up (nice to have)

• Review design specifications and provide feedback for testability and robustness

• Own end-to-end verification of PCIe (Gen6/Gen7) and CXL (3.0/4.0) subsystems, from test planning through coverage closure and signoff

• Define and execute comprehensive verification plans based on protocol specifications and micro-architecture requirements

• Architect and develop scalable UVM/System Verilog testbenches for PCIe/CXL controllers and fabric-level subsystems

• Integrate and configure PCIe/CXL VIP for subsystem and system-level verification environments

• Validate CXL.io, CXL.cache, and CXL.mem protocols, including coherency and memory semantics across complex flows

• Develop constrained-random and directed test suites to achieve high functional coverage across corner and stress scenarios

• Debug complex failures such as protocol violations, ordering issues, and coherency bugs using waveforms, logs, and protocol analyzers

• Implement System Verilog Assertions (SVA) for protocol compliance, improving early bug detection and debug efficiency

• Drive functional, code, and assertion coverage closure, identifying gaps and developing targeted tests to meet signoff goals

• Validate performance metrics (latency, throughput, QoS) under high-bandwidth and stress workloads

• Develop automation (Python/Shell) for regression management, log triage, and coverage reporting, improving productivity

• Collaborate with design, architecture, firmware and validation teams, influencing design-for-verification and mentoring junior engineers

What We're Looking For

• Bachelor’s or master’s degree in electrical engineering, Computer Engineering, or related field

• 5-10 years of experience in ASIC/SoC verification

• Strong knowledge of PCIE and CXL protocols and architecture

• Expertise in System Verilog and UVM methodology

• Experience with debugging complex verification issues

• Familiarity with industry-standard tools (e.g., simulation, waveform debugging, coverage tools)

• Solid understanding
