Senior Staff Engineer- PCIe (Host & Endpoint) Driver Development

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

Marvell's MBE Software team builds and maintains host-side software across a portfolio of PCIe Endpoint (EP) products — spanning CXL memory infrastructure, high-performance data processing platforms, and PCIe-based security accelerator cards. This is a technically broad role at the intersection of Linux kernel engineering, PCIe protocol expertise, and open source development.
You will work across multiple active product areas:
• Structera™ CXL — CXL memory-expansion controllers and near-memory accelerators for hyperscaler and enterprise data centers

• Octeon PCIe EP — Host-side drivers for Marvell's next-generation DPU/network processing platforms, enabling high-performance packet I/O, mailbox communication, and data path bring-up across x86, ARM, and RISC-V hosts

• PCIe Security Accelerator — Host software for a PCIe Gen6-based crypto/security offload card, enabling lookaside crypto, IPsec/PSP/TLS offloads, and NVMe storage integration


This is a high-impact engineering role requiring close collaboration with firmware, hardware, validation, and product teams. You will own and deliver production-quality software that ships to major hyperscalers and enterprise OEMs.

What You Can Expect

Linux Kernel PCIe EP Host Drivers

• Develop, maintain, and port Linux kernel host drivers for Marvell PCIe EP devices across multiple product lines — network DPUs, CXL memory controllers, and security accelerators
• Work with core Linux kernel subsystems: PCI/PCIe, network stack (net/ethernet), NVMe, DMA engines, and interrupt handling (MSI/MSI-X)
• Implement and maintain drivers using the Linux auxiliary bus framework, enabling modular co-existence of multiple functions on a single PCIe device
• Port and adapt drivers across Linux kernel versions and major distros (RHEL, Ubuntu, SUSE) — handling API changes, symbol deprecations, and backport requirements
• Upstream kernel driver patches to the Linux community; participate in code review cycles on kernel.org mailing lists
• Implement advanced PCIe features: SR-IOV, ATS/PASID, HDM decoder programming, and BAR mapping strategies
• Debug PCIe link bring-up issues (Gen1–Gen6), interrupt delivery, DMA coherency, and performance bottlenecks using protocol analyzers, JTAG, and kernel tracing tools

 
Host User mode Management Stack

• Develop and maintain the Marvell CCI library providing a unified API for issuing standard and vendor-specific CXL CCI commands over in-band mailbox and out-of-band MCTP interfaces
• Build and enhance userspace host management applications for device lifecycle management, functional testing, and MCTP-based out-of-band access
• Implement and maintain the DMA library with sample applications for bulk data movement between host and device memory
• Integrate with libSPDM for Component Measurement and Authentication (CMA) over MCTP/SPDM

Open Source & Community

• Actively contribute patches to the Linux kernel (PCIe, CXL, network, or DMA subsystems)

Engage with upstream maintainers, respond to review feedback, and drive patches through the submission process

What We're Looking For

• Master's degree (or equivalent) in Computer Science, Electrical Engineering, Computer Engineering, or a related field
• 6+ years of hands-on software/firmware development experience in the semiconductor or systems industry
• Experience with Linux kernel module development in one or more relevant subsystems: PCIe/PCI, network drivers, NVMe, RDMA, or GPU drivers
• Familiarity with the Linux auxiliary bus driver model and multi-function PCIe device architectures
• Strong proficiency in C programming; familiarity with C++ and Python is a plus
• Deep understanding of PCIe architecture — configuration space, BARs, TLPs, interrupts (MSI/MSI-X), DMA, and SR-IOV
• Demonstrated open source participation — patches submitted to the Linux kernel, DPDK, RDMA stack, or similar community projects
• Familiarity with Git, Gerrit code review, and CI/CD pipelines

• 
  
  Preferred Qualifications

• Experience with CXL (Compute Express Link) or familiarity with CXL.io / CXL.mem / CXL.cache specifications
• Background in NVMe host or target driver development, including NVMe
• Experience with RDMA/RoCE or GPU host-side driver development
• Familiarity with MCTP / OpenBMC stacks and out-of-band device management
• Familiarity with ARM SoC architecture (Neoverse V2 / Cortex-M) and embedded Linux
• Familiarity with security practices in firmware/software development (secure boot, SPDM attestation)
• Knowledge of DRAM architecture (DDR5, SPD, error scrubbing, PPR) is a plus

•  
  Interpersonal & Team Attributes

• Active open source contributor with a track record of merged patches — patches in the Linux kernel tree.
• Strong written and verbal communication skills — able to author clear design documentation and driver guides
• Collaborative mindset; comfortable working across firmware, hardware, validation, and customer-facing teams
• Self-driven with the ability to take end-to-end ownership of components — from design through customer support
