Introduction:

We’re building a next-generation, application-class RISC‑V MPU SoC platform for Linux systems - bringing together multimedia, industrial connectivity, security, and high-speed I/O.

In the Platform Software team, you will be the technical owner for PCIe across the stack: boot-to-user-space enablement, Linux kernel/driver integration, and automated validation (AVV) on virtual platforms/FPGA and first silicon. You’ll partner closely with architects and hardware teams to de-risk the PCIe subsystem, drive bring-up readiness, and deliver a production-quality SDK experience.

Key Responsibilities

• PCIe Linux enablement & integration: enable and maintain PCIe Root Complex and/or Endpoint functionality on a 64-bit RISC‑V MPU Linux platform.

• Bring up the PCIe controller, PHY/SerDes integration, clocks/resets, link training (LTSSM), and interrupt routing.

• Drive kernel/BSP enablement: Device Tree bindings, address translation/windows, IOMMU interactions (where applicable), and power management (ASPM, suspend/resume).

• Own PCIe functionality in Linux: enumeration, configuration space, BAR programming, DMA engines, and interrupt mechanisms (legacy/MSI/MSI‑X).

• Enable and validate reliability features: link up/down recovery, error handling (AER), timeouts, and robustness across hot reset and stress scenarios.

• Deliver PCIe-ready SDK releases: integration, regression validation, and developer-facing documentation/debug guides (e.g., lspci workflows, link/debug playbooks).

• AVV & silicon validation (pre/post-silicon): create test plans and automation to validate PCIe functionality, performance, and interoperability on FPGA/emulation and first silicon.

• Contribute to shift-left validation using virtual platforms/emulation/FPGA; build reusable PCIe validation tests for link bring-up, enumeration, DMA throughput, and error injection.

• Debug and root-cause PCIe issues across HW/FW/kernel using logs, traces, and lab equipment (e.g., JTAG, protocol analyzers/exercisers, oscilloscopes/BERT where applicable); drive fixes to closure.

• Cross-functional ownership: partner with architects, RTL/SerDes/PHY, board, and platform teams to define requirements, de-risk schedules, and land PCIe features.

• Own PCIe feature planning: lane/width/speed targets (Gen2/Gen3/Gen4 as applicable), RC/EP mode requirements, reset/clocking, and bring-up milestones.

• Provide bring-up and validation feedback that influences PCIe architecture decisions (debug hooks/observability, compliance testability, error reporting, and recovery behavior).

• Align with internal and external stakeholders on deliverables, bug triage, and release readiness for PCIe enablement.

• Customer & ecosystem engagement: support early adopters and upstream fixes when appropriate (kernel, Device Tree, PCI subsystem/endpoint framework).

• Work with OEMs/Tier‑1s during bring-up and PCIe interoperability (different endpoints/switches); contribute patches upstream when it improves maintainability.

Required Qualifications

• B.E./B.Tech or M.E./M.Tech in Computer Engineering, Electrical Engineering, or a related field.

• Strong experience with minimum 8-12 years in Embedded Linux platform/BSP and device-driver development.

• Expert-level C programming; comfortable reading and modifying kernel, driver, and low-level firmware code.

• Strong Linux internals knowledge: boot flow, memory/interrupt subsystems, concurrency, and performance debugging.

• Hands-on SoC/platform bring-up experience, including high-speed I/O enablement and ownership mindset for subsystem quality.

• Hands-on with U‑Boot, Linux kernel, Device Tree, and Yocto/OpenEmbedded; experience integrating and validating PCIe in BSP/SDK releases.

• Strong debugging skills with GDB and at least one of OpenOCD/JTAG, Lauterbach, or similar tools; able to debug complex HW/SW interactions.

• Experience working on FPGA, emulation, or early-silicon platforms for bring-up/validation.

Good to Have

• Deep PCIe knowledge and familiarity with Linux PCI subsystem (Root Complex and Endpoint concepts, enumeration/config space, AER).

• Experience with PCIe compliance/interoperability testing and post-silicon triage (link training/LTSSM, equalization, error injection, throughput).

• Exposure to advanced PCIe features such as SR‑IOV, ATS/PRI, hot-plug/hot reset, and PCIe switches is a plus.

• Familiarity with platform security boundaries relevant to PCIe (DMA attack surface, IOMMU/SMMU concepts, secure boot boundaries).

• Experience with QEMU, virtual platforms, or emulation workflows used for early driver/test development (including PCIe RC/EP scenarios where applicable).

• Exposure to CI/CD and automated validation (Python/shell test frameworks, dashboards, regressions) for continuous PCIe quality.

What We Offer

• Build a RISC‑V MPU platform from the ground up and see it shipped in real products.

• End-to-end ownership across pre-silicon → FPGA → first silicon → production SDK releases.

• Work closely with CPU architects and SoC teams; your data drives decisions.

• Deep technical work, strong peer group, and long-term growth on a strategic platform
