We build the high-performance data plane software that powers IOS-XR platforms, leveraging cutting-edge Silicon One (SiOne) Network Processing Units (NPUs).\nOur team operates at the intersection of hardware and software, defining how packets traverse the internet's backbone. We are transitioning into a new era of embedded development, utilizing modern AI-assisted methodologies to deliver features faster and with higher quality.\nYour Impact\nAs a Software Engineer, you will focus on the design, coding, and optimization of our forwarding software. You will be responsible for delivering high-quality code for complex Layer 2 and Layer 3 forwarding features, ensuring they extract maximum performance from our NPUs. You will act as a key technical contributor, applying modern software practices and AI-driven workflows to streamline development and debugging.\nKey Responsibilities\n Feature Design & Implementation: 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.\nNPU Data Plane Programming: Implement data plane logic to optimize packet processing. Translate network protocol requirements into efficient NPU microcode and SDK interactions.\nDebugging & Root Cause Analysis: 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.\nPerformance Optimization: Profile and tune code to minimize latency and maximize throughput, ensuring the software meets strict service provider performance metrics.\nModern Development Practices: Actively apply AI/LLM-based tools for code generation, unit test creation, and static analysis to improve individual productivity and code quality.\nMinimum Qualifications\nBS/MS in Computer Science, Electrical Engineering, or related field.\n5-10 years of experience in embedded software development for networking products.\nStrong proficiency in Embedded C for software development and Python for scripting and test automation.\nKnowledge of NPU-based data plane architectures (e.g., Broadcom DNX, Silicon One, or ezChip). Understanding of pipelining, table management, and packet processing flows.\n Forwarding Protocols (L2/L3): 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.\nUnderstanding of router deployments in Service Provider networks (Core, Peering).\nAbility to debug issues at the component level, including hardware/software interactions and memory management.\nExperience with CI/CD pipelines, Git, and code review processes.\nExperience working on tools such as Clearcase, Valgrind, DDTS, GDB, etc.\nPreferred Qualifications\nExperience with **IOS-XR** or similar carrier-grade network operating systems.\nKnowledge of Internet Protocols (TCP/UDP, IPv4/IPv6).\nExposure to Networking Protocols (L2/L3, QoS, ACLs,).\nExperience with BCM, Sione, Ezchip NPU programming\nFamiliarity with AI/ML tools for software engineering (e.g., Copilot for code, AI for log analysis).\nWhy Cisco?\nAt Cisco, we’re revolutionizing how data and infrastructure connect and protect organizations in the AI era - and beyond. We’ve been innovating fearlessly for 40 years to create solutions that power how humans and technology work together across the physical and digital worlds.
