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.

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

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
