## Description

Cisco Security Business Group (SBG) is looking for a Security Deployment Engineer Technical Leader in a customer-facing role that focuses on technical leadership, two-way advocacy, and expertise across our security portfolio.

This role combines deep networking and security knowledge with the ability to represent engineering to customers and customers to engineering.

You operate from both viewpoints: represent engineering to the customer, and represent the customer in engineering discussions - with strong customer advocacy at the center. You own complex escalations and translate requirements, RCAs, and technical decisions Japanese <-> English without losing context on either side, and lead technical incident discussions with Japanese enterprise customers, ensuring clear communication and proactive management to meet and exceed their expectations.

Key responsibilities:

- Lead technical incident discussions for Japanese enterprise accounts, ensuring timely resolution and high customer satisfaction.

- Participate in an on-call rotation to provide critical support and ensure high availability for our enterprise customers as needed.

- Lead L3/L4 troubleshooting across VPN, zero trust access, web inspection in the cloud, CASB, DLP, firewall policy, and hybrid cloud deployments.

- Perform packet capture and packet analysis; use deep packet inspection context to isolate connectivity, performance, and policy issues (IPsec tunnels, IPv4/IPv6, DNS, TLS/SNI, routing, NAT, IP pools).

- Drive proactive account health: capacity, upgrade readiness, config/policy drift, and repeat-incident prevention.

- Capture customer configurations and run daily regression checks to confirm everything is working as intended - surfacing issues before they affect the customer environment.

- Build clean escalations for engineering - timeline, impact, repro, logs, pcaps, redacted configs - and translate outcomes back to the customer.

- Use AI-assisted log analysis with strong judgment; don't ship unverified conclusions to either side.

- Script (Bash/Python) for diagnostics, health checks, and lab reproduction.

- Mentor junior liaison engineers on two-way communication and technical depth.

Minimum qualifications:

- Fluent Japanese and English for technical communication (written and spoken).

- Comfortable speaking for both sides: customer-facing updates and engineering-facing escalation write-ups from the same incident.

- Strong customer advocacy - you represent the customer's interests credibly while staying factually accurate with engineering.

- 10 years in network/security operations, customer support engineering, or professional services.

- Solid TCP/IP (IPv4/IPv6), DNS, routing, NAT, IPsec tunnels, and TLS fundamentals.

- Familiarity with AWS basics: VPC, subnets, security groups, CloudWatch, hybrid connectivity.

- Packet capture familiarity (Wireshark/tcpdump) and structured troubleshooting.

- Experience with cloud container technologies such as Kubernetes: deployments, services, scaling, basic kubectl troubleshooting.

- Working knowledge of one or more of the following technologies: VPN, zero trust, web inspection in the cloud, CASB, DLP, and firewall policy.

- Bash scripting; Python a plus.
