About The Position

Micas Networks is seeking a hands-on Senior BSP / Platform Software Engineer to own the board support package (BSP) and low-level platform software for its SONiC-based data center switches. The engineer will bring up new switch hardware from first power-on through production, develop and maintain bootloaders, Linux kernel drivers, and platform layers for SONiC and other open network operating systems, and work with hardware, silicon-vendor, and customer engineering teams to resolve low-level issues. The role calls for deep experience bringing up bare-metal or white-box Ethernet switches built on Broadcom switch silicon, end-to-end understanding of x86 and ARM boot and driver stacks, and confidence debugging at the hardware/software boundary. The successful candidate will own platform software across multiple product generations and help mentor other engineers.

Requirements

BS or MS in Computer Science, Electrical/Computer Engineering, or a related field.
8+ years of embedded or platform software development, including at least 5 years of BSP development and board bring-up on network switches or comparable embedded systems.
Strong C programming and debugging skills in the Linux kernel and user space; proficiency in Python and shell scripting.
Hands-on experience writing Linux kernel drivers and working with low-level interfaces such as I2C/SMBus, SPI, UART, PCIe, MDIO, GPIO, and Ethernet.
Proven experience bringing up new boards, including bootloaders (U-Boot, BIOS/UEFI), kernel porting, and hardware validation alongside hardware engineers.
Experience with Broadcom switch silicon and SDK (XGS and/or DNX) on bare-metal/white-box data center switches.
Working knowledge of SONiC platform architecture, ONIE, and Yocto or Debian-based build systems.
Ability to read schematics and datasheets and use lab tools such as an oscilloscope, logic analyzer, and JTAG debugger to distinguish hardware issues from software issues.

Responsibilities

Lead board bring-up of new switch platforms from first power-on through EVT/DVT/PVT and production, working with hardware engineers to debug and resolve critical low-level hardware/software issues.
Develop, customize, and maintain BSPs for x86_64 and ARM CPU subsystems, including BIOS/UEFI and U-Boot configuration, Linux kernel porting, device tree/ACPI, and Yocto or Debian-based build layers.
Develop and maintain Linux kernel drivers for CPLD/FPGA, I2C/SMBus multiplexers, PCIe, SPI, UART, MDIO, and GPIO, and for platform peripherals such as optical transceivers, fans, PSUs, thermal sensors, and LEDs exposed through sysfs.
Implement and maintain the SONiC platform layer, including platform modules, the sonic-platform Python API, PMON daemons, and device and port configuration.
Port and integrate the Broadcom SDK (XGS/DNX) and SAI on Tomahawk/Trident-family switch silicon, including port mapping, SerDes/PHY settings, and chip configuration files.
Port and maintain ONIE (and ONL where needed) for new platforms, and own the installer and boot flow for SONiC and other NOS images.
Develop and integrate OpenBMC on ASPEED BMCs, including IPMI and Redfish, and deliver in-field firmware updates for BIOS, CPLD/FPGA, BMC, and ONIE.
Build hardware validation and diagnostic tools, and use kernel crash tooling, JTAG, and lab instruments to root-cause failures in the lab and customer deployments.
Maintain BSP code in Git, perform code reviews, own platform software builds and releases, and contribute to CI and automated regression testing.
Serve as the platform software point of contact for hyperscaler, OEM, and ODM partners, and work with Broadcom and other component vendors on technical escalations.
Help mentor other engineers on the team.
