• SAI & HAL Development: Design, implement, and extend the Switch Abstraction Interface (SAI) and Hardware Abstraction Layer (HAL) to expose hardware capabilities to the SONiC control plane (Syncd, Orchagent).
• ASIC SDK Integration: Act as the primary software expert for integrating, upgrading, and troubleshooting silicon vendor SDKs (e.g., Broadcom SDKLT/OFA, Marvell, etc.) into our networking software stack.
• Feature Enablement: Implement advanced forwarding and hardware-accelerated network features (such as L2/L3 routing, ACLs, QoS, VxLAN, and telemetry) at the driver and abstraction layers.
• Performance Optimization: Profile and debug silicon-level software issues, resolving complex pipeline bottlenecks, packet drops, and memory leaks between the SDK and system software.
• Community Co-existence: Collaborate with the open-source SONiC community and semiconductor vendors to upstream extensions, implement new SAI APIs, and resolve architectural issues.
• Cross-Functional Execution: Work closely with in office hardware engineering, platform validation, and QA teams in San Jose to bring up new hardware platforms from scratch. Required Qualifications & Criteria
• ASIC SDK

Experience:




6+ years of experience working directly with low-level networking ASIC SDKs (e.g., Broadcom, Marvell/Cavium, Barefoot/Intel).
• SAI & HAL Mastery: Proven, hands-on experience developing or extending the Switch Abstraction Interface (SAI) or custom Hardware Abstraction Layers (HAL).
• Advanced Systems Programming: Expert-level proficiency in C and C++ within a Linux development environment.
• Network OS Architecture: Deep understanding of data-plane forwarding architectures, open networking software, and specifically how SONiC/SAI architectures manage underlying silicon states.
• Low-Level Debugging: Mastery of debugging tools such as GDB, Valgrind, Wireshark, and hardware network testers (e.g., Ixia, Spirent).
• L2/L3 Networking Protocols: Strong conceptual and implementation knowledge of switching/routing mechanics (BGP, ECMP, EVPN, VLANs, LACP). Preferred Qualifications (Nice to Have)
• Direct experience with the inner workings of SONiC daemons like syncd, orchagent, and Redis database states.
• Experience with Linux kernel network stack development or custom kernel drivers.
• Active contribution or working knowledge within open hardware/software forums (OCP, Linux Foundation).
