Principal Engineer - Silicon Validation Engineer

Develop and maintain embedded firmware and software drivers to control and validate high-speed ASIC SoCs across various product lines using custom evaluation systems under pre-silicon emulation platforms like FPGA/Zebu and post-silicon environments.

Create and maintain kernel and user space drivers under Linux tailored to Marvell’s controllers and high-speed I/O interfaces supporting Ethernet MAC/Phy, PCIe, NVMe, CXL protocols, and low-speed I/O interfaces such as I2C, I3C, SMBus, SPI, etc.

Understand the I/O stack from host to device, including both hardware and software components.

Develop and maintain host-side test application software under Linux OS.

Conduct experiments and data collection on the bench, producing professional reports that detail experimental results.

Collaborate with design and architecture teams to produce application notes, reference firmware, software libraries, and other technical documentation for new and existing SoC features.

Working knowledge of high-speed Ethernet MAC/phy subsystems interface and characterization. Extensive knowledge of the physical and protocol levels (PIPE I/F, PCS, MAC) of one or more common high-speed interfaces is an asset.

Analyze and visualize data using Excel and Python.

Excellent troubleshooting skills to resolve silicon issues and provide technical/debug support to customers.

Bachelor’s degree in Computer Science, Electrical Engineering, or related fields and 10+ years of related professional experience OR Master’s degree and/or PhD in Computer Science, Electrical Engineering, or related fields with 5+ years of work experience.

Experience with assembly language for low-level programming and proficiency in C/C++ for embedded systems.

In-depth knowledge of Ethernet MAC and PHY layers. Understanding of IEEE 802.3 standards.

Knowledge of SPI, I2C, UART, and other hardware communication protocols.

Proficiency in using lab equipment like oscilloscopes, logic analyzers, and spectrum analyzers.

Skills in pre-silicon validation (emulation platform) and post-silicon bring-up.

Ability to work closely with cross-functional teams, including hardware engineers, software developers, and product managers.

Familiarity with ARM CPUs (multicore/cluster) and their internals.

Experience with low-level hardware interfaces and bare-metal software development

Knowledge of at least one protocol specification like  NVMe, PCIe, CXL or Nand Flash (JEDEC Spec) will be a Plus

Experience in Linux user space I/O driver development and debugging using the SPDK/DPDK stack will be a Plus

Proficiency in Excel and Python programming will be a Plus.
