Software Engineer (Embedded C, forwarding protocols | 4-10 years | Bangalore)

Overview

Software Engineer on the MIG Platform Forwarding team, focused on designing, coding and optimizing high-performance forwarding software for IOS-XR platforms and Silicon One Network Processing Units.

What you'll do

• Own the design and development of specific forwarding features within the IOS-XR platform.
• Write high-performance, production-grade code for QOS, Mirroring, Slowpath, OAM, Layer 2 (EVPN, VPLS) and Layer 3 (SRv6, Segment Routing, MPLS) technologies.
• Implement data plane logic to optimize packet processing.
• Translate network protocol requirements into efficient NPU microcode and SDK interactions.
• Investigate and resolve complex software defects found during internal testing or customer deployments.
• Analyze logs, core dumps and packet traces to distinguish between NPU behavior and software logic issues.
• Profile and tune code to minimize latency and maximize throughput.
• Apply AI/LLM-based tools for code generation, unit test creation and static analysis.

What you'll need

• BS/MS in Computer Science, Electrical Engineering or a related field.
• 5-10 years of experience in embedded software development for networking products.
• Strong proficiency in Embedded C for software development and Python for scripting and test automation.
• Knowledge of NPU-based data plane architectures, such as Broadcom DNX, Silicon One or ezChip.
• Understanding of pipelining, table management and packet processing flows.
• Strong understanding and implementation experience in Qos, Mirroring, OAM, Layer 2 (EVPN, VPLS) or Layer 3 routing (SRv6, Segment Routing, MPLS, IPv4/v6).
• Implementation experience with TE-Tunnels, GRE tunnels, BFD, BGP Flowspec, ACLs or Slowpath forwarding mechanisms.
• Understanding of router deployments in Service Provider networks, including Core and Peering.
• Ability to debug issues at the component level, including hardware/software interactions and memory management.
• Experience with CI/CD pipelines, Git and code review processes.
• Experience working on tools such as Clearcase, Valgrind, DDTS and GDB.

Nice to have

• Experience with IOS-XR or similar carrier-grade network operating systems.
• Knowledge of Internet Protocols, including TCP/UDP and IPv4/IPv6.
• Exposure to Networking Protocols, including L2/L3, QoS and ACLs.
• Experience with BCM, Sione and Ezchip NPU programming.
• Familiarity with AI/ML tools for software engineering, such as Copilot for code and AI for log analysis.
