Senior Platform Software Engineer

About the Job

NVIDIA is building a new wave of accelerated computing systems, where platform manageability, secure firmware, and high-performance networking must work as one coherent architecture. We are looking for an engineer to help define and implement OpenBMC-based management for systems that include host CPUs, BMCs, and coordinated top-of-rack Ethernet switching functionality.

What You'll Be Doing

• Architect and implement OpenBMC support for platforms where the BMC handles host system functions and a coordinated ToR Ethernet switch subsystem.
• Define the end-to-end switch-management architecture across OpenBMC D-Bus services, bmcweb/Redfish APIs, persistent configuration, eventing, telemetry, security, and backend switch control interfaces.
• Develop OpenBMC object models and services for switch inventory, switch ASICs, front-panel ports, internal ports, PHYs, optics, retimers, VLANs, LAGs, FDB entries, counters, sensors, and health state.
• Implement L2 networking capabilities including port admin control, speed and FEC configuration, auto-negotiation, breakout, VLAN creation and membership, access/trunk mode, MAC learning, FDB management, flooding controls, link aggregation, and loop-prevention features.
• Build backend abstraction layers that can integrate with Linux switchdev/netlink, SAI/SONiC/SWSS-style components, DENT-style Linux networking components, or vendor switch ASIC SDKs.
• Work closely with hardware, ASIC, security, firmware, QA, manufacturing, and cloud infrastructure networking teams to influence board architecture, schematics, manageability interfaces, and production test strategy.

Write and review design specifications, API documentation, code, unit tests, hardware-in-loop tests, integration tests, and QA plans required to productize the architecture.
