- Work with Broadcom or Marvell switching ASICs to implement hardware-accelerated L2/L3 forwarding features.
- Integrate software control-plane functionality with ASIC hardware abstraction layers and SDK APIs.
- Debug packet forwarding, route programming, next-hop resolution, ECMP, and multicast issues.
- Analyze packet captures, system logs, routing tables, and hardware table dumps to identify and resolve defects.
- Troubleshoot networking issues involving VLANs, SVIs, ARP, IPv6 Neighbor Discovery, IP multicast, and interface management.
- Collaborate with hardware, platform, QA, and system engineering teams to deliver reliable networking features.
- Participate in design reviews, code reviews, unit testing, integration testing, and performance optimization.
