Consulting Engineer

Meet the Team Cisco's Customer Experience (CX) Professional Services Service Provider PDI (Plan, Design, Implement) team is a group of elite technical experts driving the architecture, deployment, and optimization of 5G Core, Telco Cloud, and edge computing infrastructures for Japan's leading telecommunications carriers. We are leading the monumental industry shift from legacy hardware-centric networks toward modern, agile, and resilient Telco Cloud platforms powered by Kubernetes and advanced virtualization. Working in close synergy with Cisco's global Business Units (BU) and Centers of Excellence (CoE), we operate as One Team to architect and deploy mission-critical mobile platforms that demand world-class reliability, ultra-low latency, and massive throughput.

As a Consulting Engineer , you will act as a technical lead responsible for the end-to-end design, implementation, and performance optimization of Kubernetes/KVM-based cloud-native infrastructures and high-speed data planes leveraging CNDP (Cloud Native Data Plane) for Japan's tier-1 Service Provider clients. You will own the complete technical delivery lifecycle-from customer requirement scoping and Detailed Design (LLD) authoring to configuration manifest creation, PoC/lab staging, field implementation, kernel/data-plane tuning, and production cutover-ensuring a robust, high-performance foundation for 5G Cloud-native Network Functions (CNFs) and Virtual Network Functions (VNFs). What You'll Do • Cloud-Native Architecture & Design: Lead the High-Level and Low-Level Design (HLD/LLD), parameter definition, and test plan creation for bare-metal / VM-based Kubernetes and KVM/OpenStack virtualization platforms in 5G Core and edge environments. • Data Plane Acceleration & Performance Tuning: Apply high-speed packet processing technologies-including CNDP (Cloud Native Data Plane), DPDK, SR-IOV, and eBPF-to conduct benchmarking, kernel parameter tuning, and throughput optimization meeting stringent carrier-grade SLAs. • Container Network Interface (CNI) Engineering: Architect, integrate, and troubleshoot advanced container networking environments utilizing Multus CNI, Calico, SR-IOV CNI, and high-performance routing protocols. • PDI Technical Delivery & Cutover Ownership: Serve as the technical lead across the full PDI lifecycle, driving staging validation, on-site deployment, cutover runbook execution, and real-time risk mitigation during critical maintenance windows. • Global Collaboration & Knowledge Scaling: Partner with global architecture teams (India CoE, US BU Engineering) to resolve complex product roadblocks, while translating project learnings into reusable templates and design collateral for the broader team.

You are a seasoned infrastructure and platform engineer with deep Linux/Kubernetes expertise, a strong data-plane engineering mindset, and proven execution discipline in large-scale Service Provider environments. Minimum Qualifications: • 5+ years of hands-on experience in the design, deployment, and operation of container platforms (Kubernetes / Docker) or enterprise virtualization environments (KVM / OpenStack). • Deep understanding of Linux OS internals (RHEL / Ubuntu), kernel parameter tuning, system administration, and container network stack troubleshooting. • Practical knowledge or implementation experience with accelerated data-plane technologies (e.g., CNDP, DPDK, SR-IOV, eBPF , or fast packet processing). • End-to-end PDI (Plan, Design, Implement) delivery capability, including authoring Detailed Design documents (LLD), execution runbooks, and test verification procedures. • Native or business-level fluency in Japanese (client-facing advisory and technical documentation) with professional working proficiency in English (collaborating with global engineering teams). Preferred Qualifications: • Practical experience deploying or validating 5G Core components (UPF, SMF), vEPC, or Telco CNFs
