Hardware Engineer - Gigamon (Chennai)

Responsibilites:

Lead the architecture and bring-up of new hardware platforms, including hardware-software interface design, board bring-up planning, and system-level debugging.

• Design, develop, and debug low-level software, including bootloaders (e.g., U-Boot), system firmware (e.g., BIOS), and Linux kernel device drivers for x86, ARM, and MIPS architectures.
• Develop and maintain custom kernel drivers for peripherals (I2C, SPI, UART, USB, PCIe) and enhance the Linux networking stack, contributing to open-source initiatives such as ONIE and OpenBMC.
• Architect and implement Board Management Controller (BMC) firmware, leveraging standards like IPMI and Redfish, and drive solutions based on the OpenBMC framework.
• Collaborate with security teams to implement platform security features, including Hardware Root of Trust (HROT).
• Guide development and debugging efforts for networking hardware, including Broadcom and Marvell switch silicon (e.g., Trident 4, Tomahawk, CN9XXX), high-speed SerDes, optical modules, and Ethernet/PCIe PHYs.
• Architect and maintain embedded Linux build systems (Yocto, Buildroot) and adapt enterprise Linux distributions (e.g., Rocky Linux) for custom hardware.
• Mentor engineers, conduct code reviews, and drive continuous improvement through agile methodologies and best practices.

Requirements:

Bachelors degree in Electronics, Electrical, or Computer Science Engineering (required).

• 10+ years of professional experience in software design and development for hardware networking products.
• Demonstrated leadership in hardware bring-up, including debugging with lab equipment (logic analyzers, trace32, BIOS/CPLD programming tools) and schematic analysis.
• Deep expertise in embedded systems, including platform firmware (U-Boot, BIOS), BMC architecture, and embedded security (HROT).
• Mastery of C programming (and C++ for embedded systems), Linux kernel internals, device driver development, and memory/process management.
• Extensive experience with embedded Linux build systems (Yocto, Buildroot) and enterprise Linux distributions (e.g., Rocky Linux).
• Proven track record with networking protocols (TCP/IP, Ethernet), high-speed interfaces (SerDes, Ethernet/PCIe PHYs), and switch silicon from major vendors such as Broadcom and Marvell.
• Experience with optical modules and modern hardware management interfaces (OpenBMC, IPMI, Redfish).
• Strong background in technical leadership, system architecture, feasibility analysis, and technical specification development.
