I/O Devices, IPC Software Architect

Job Title: I/O Devices, IPC Software Architect

We are seeking a Principal Engineer in I/O Device Drivers and System Software with 12–15 years of hands-on experience in developing, debugging, and optimizing low-level drivers, high-performance inter-processor communication (IPC) frameworks, and storage/networking subsystems. This role requires deep knowledge of Linux kernel internals, IPC mechanisms, PCIe, Ethernet, CAN, SR-IOV virtualization, and storage interfaces, with strong expertise in automotive-grade and edge system software. The ideal candidate will provide technical leadership, work closely with cross-functional teams including silicon and hardware architects, and mentor junior engineers while driving end-to-end system solutions.

Key Responsibilities

• Architect, design, and implement Linux kernel drivers and BSP components for I/O subsystems including PCIe, Ethernet, CAN, USB, and storage (NVMe, SAS/SATA, eMMC, UFS).
• Design, implement, and optimize high-throughput, low-latency IPC mechanisms (shared memory, mailbox, RPMsg, virtio, sockets) across heterogeneous compute subsystems (CPU, DSP, accelerators).
• Enable SR-IOV, virtualization, and multi-function device drivers for scalable and secure I/O virtualization.
• Architect cross-processor communication frameworks for real-time and safety-critical automotive/edge applications.
• Design and optimize I/O and storage drivers for deterministic performance, QoS, and real-time guarantees.
• Perform Linux kernel debugging (crash dumps, ftrace, perf, kgdb, stack traces) to resolve complex issues spanning firmware, kernel, and hardware.
• Drive silicon bring-up, IPC framework validation, and driver–firmware integration for I/O and compute subsystems.
• Work across silicon design, hardware, architecture, and system software teams to define IPC/I/O requirements, architect solutions, and ensure timely deliverables.
• Collaborate with automotive system architects, hardware, and silicon teams to ensure compliance with functional safety and reliability requirements.
• Mentor and guide junior engineers, conduct design/code reviews, and lead critical debug and system integration task forces.
• Contribute to Linux kernel community discussions and open-source integration in IPC, networking, storage, or PCIe domains.

Required Skills & Experience

• 12–15 years of embedded/Linux system software development with a focus on device drivers, IPC frameworks, and kernel subsystems.
• Expertise in:
• IPC frameworks: shared memory drivers, mailboxes, RPMsg, virtio, sockets, inter-VM communication.
• PCIe subsystem (enumeration, error handling, hot-plug, peer-to-peer, SR-IOV, ATS/PRI).
• Networking drivers: Ethernet, TSN (Time-Sensitive Networking)
• Automotive networking: CAN/CAN-FD, LIN, diagnostics (UDS/DoIP), AUTOSAR integration.
• Storage drivers: NVMe, eMMC.
• Strong knowledge of Linux kernel internals: interrupts, DMA engines, memory management, caching, synchronization primitives, and virtualization.
• Proficiency in C/C++ and scripting languages (Python, Shell) for automation and validation.
• Excellent Linux kernel debugging skills
• Familiar to functional safety and reliability standards (ISO 26262, ASIL levels).
• Proven ability to lead cross-functional teams (silicon, hardware, software, validation) and drive cross-layer debug strategies for IPC/I/O subsystems.

Preferred Qualifications

• Hands-on experience with virtualization technologies (KVM, Xen, QEMU, SR-IOV device assignment).
• Experience with real-time operating systems (RTOS) and deterministic Linux (PREEMPT-RT).
• Familiarity with heterogeneous computing platforms (CPU + accelerators + VPU/DSP + storage offload).

Education

• Bachelor's or Master's degree in Computer Engineering, Electrical/Electronics Engineering, or related field.
