About the Role
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).
Responsibilities
- 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.
- 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.
- Architect, integrate, and troubleshoot advanced container networking environments utilizing Multus CNI, Calico, SR-IOV CNI, and high-performance routing protocols.
- 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.
- 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.
Requirements
- 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).
