Software Engineer

Job posting may be removed earlier if the position is filled or if a sufficient number of applications are received.

You will be working with best-in-class engineers and technical visionaries on a highly productive team that owns next generation production development.

We love our work and are passionate about our role in changing the future of networking.

Our team is responsible for delivering advanced simulation solutions and infrastructure for internal and external customers. Our scope covers compute infrastructure, NPU modeling, system simulation, and advanced AI tool development. We support IOS-XR, SONIC, and NXOS network operating systems. A large portion of our technology is made available to customers to streamline their adoption of Cisco hardware portfolio.

As a SONiC Platform Engineer, you will be at the forefront of the industry's transition toward open-source networking. You will be responsible for porting and optimizing the SONiC operating system to run on models of Cisco's highest end routers & switches, based on the Silicon One ASIC family and Nexus platforms. This role bridges the gap between open-source community code and carrier-grade networking hardware.

• Platform Porting & Bring-up:Lead the effort to port SONiC onto new Cisco ASICs (Silicon One) and virtual platforms. This includes configuringONIE(Open Network Install Environment), managing bootloaders, and ensuring the Debian-based OS initializes correctly on bare-metal hardware.
• SAI & Driver Integration:Integrate and fine-tune theSwitch Abstraction Interface (SAI)andSyncdlayers. You will ensure that the hardware-specific SDK calls are correctly mapped to SONiC's logical state.
• Hardware-Software Hardening:Own the "bring-up" of peripheral components, including thermal sensors, fans, PSUs, and optics through Platform APIs andBSP (Board Support Packages).
• Full-Stack Qualification:Design and execute end-to-end qualification cycles. You will be responsible for ensuring that the platform meets performance and stability benchmarks before it reaches the customer.
• Regression Automation:Develop and maintain massive regression test suites usingPytest,PTF (Packet Test Framework), andAnsible. You will automate the detection of regressions in the data plane (forwarding) and control plane (BGP/LACP) across every software build.
• Triage & Debugging:Perform deep-dive root-cause analysis of failures during bring-up, using tools likeGDB,Tcpdump, and ASIC-level registers to identify if a bug resides in the OS, the SAI layer, or the hardware itself.
• Leverage AI/LLM: Optimize development workflow use cutting edge LLM based tools.

• Bachelors + 7 years of related experience OR Masters + 4 years of related experience OR PhD + 1 year of related experience.
• 4+ years of experience inHardware Bring-uporNOS Platform Engineering.
• Experience qualifying networking platforms for high-scale data center deployments.
• Experience with Python for building automated test frameworks and interacting with REST/gRPC APIs
• Experience with Linux

• NOS Internals:Strong understanding of SONiC architecture, specifically the interaction betweenRedis (ConfigDB/StateDB),SwSS, andSyncd.
• Hardware Interface:Experience withASIC SDKsand theSAI(Switch Abstraction Interface) standard.
• Linux Systems:Expert knowledge of Linux kernel drivers, systems, and containerization (Docker) in a networking context.
• Testing Tools:Hands-on experience with traffic generators (Spirent, IXIA) and open-source test tools likeScapyandPTF.
