仕事内容
Meet the Team
- Cisco's Customer Experience (CX) Professional Services is at the forefront of the global 5G revolution. We partner with Japan's tier-1 mobile network operators (MNOs) to architect, deploy, and optimize mission-critical 4G/5G mobile packet core networks and cloud-native mobile infrastructures.
- Our team combines deep 3GPP domain expertise with cutting-edge cloud-native platform engineering. We operate in a highly collaborative, fast-paced environment where we co-innovate with Cisco's global Mobility Business Units (BU), Centers of Excellence (CoE), and tier-1 service providers to deliver ultra-reliable, high-capacity, and low-latency mobile platforms supporting millions of subscribers.
Your Impact
- As a Customer Delivery Architect for Mobility & 5G, you will serve as the principal technical authority and trusted advisor leading the end-to-end architectural design, validation, and commercial deployment of Cisco's 5G Standalone (SA) / Non-Standalone (NSA) Converged Core and Cloud-Native Network Functions (CNF).
- You will bridge the gap between customer business objectives and technical delivery execution. You will own the high-level architecture (HLD), low-level parameters (LLD), end-to-end call flow design, and performance optimization for 5G Core network functions (UPF, SMF, AMF, PCF, NRF) across bare-metal and containerized Telco Cloud environments, ensuring flawless execution during live carrier cutovers and network migrations.
What You'll Do
- 5G Core Architecture & Solution Design: Lead the architecture, design, and integration of Cisco 5G SA/NSA Core solutions, Converged Packet Core (vEPC / 5GC), and Control and User Plane Separation (CUPS) architectures for major Japanese telecommunications carriers.
- Cloud-Native & User Plane Engineering: Architect high-throughput, low-latency 5G User Plane Functions (UPF) and Service-Based Architecture (SBA) control planes running on modern container platforms (Kubernetes / OpenStack / Bare-metal Telco Cloud).
- End-to-End Call Flow & Protocol Design: Define detailed signaling call flows, session management, policy control, charging (CHF/Diameter), subscriber data management, and network slicing across 3GPP (Rel 15/16/17) standards.
- PDI Delivery & Cutover Governance: Act as the lead delivery architect across the full project lifecycle (Plan, Design, Implement)-directing lab staging, PoC benchmarks, migration strategies, operational runbooks, and real-time risk decision-making during high-stakes maintenance windows.
- Strategic Advisory & Trusted Partnership: Partner closely with telco engineering directors, CTO office stakeholders, Cisco Account Teams (AM/CSM), and specialist SEs to shape multi-year technology roadmaps and drive architectural evolution.
- Technical Leadership & Mentorship: Guide and mentor senior consulting engineers, drive delivery quality control, and collaborate with global development teams (Mobility BU / TAC) to resolve critical software and protocol roadblocks.
Who You'll Work With
- You will collaborate with a passionate, multidisciplinary team of mobile core specialists, cloud-native architects, and project leaders within Cisco CX Japan. You will work closely with Account Executives, Solution Architects, global CoE delivery centers, and the Cisco Mobility BU, while interfacing directly with executive technical leaders at Japan's top telecommunications operators.
Who You Are
- You are a distinguished mobile packet core architect with extensive experience designing and deploying large-scale carrier mobile networks. You combine deep 3GPP protocol mastery with modern cloud-native virtualization acumen and exceptional client leadership skills.
