Security Deployment Engineer Technical Leader

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.

Cisco offers a comprehensive end-to-end security portfolio covering on-premises, cloud, on-device, and hybrid environments -including VPN, zero trust, web inspection in the cloud, firewall, CASB, and DLP. This flexibility allows customers to select solutions tailored to their needs and transition seamlessly as requirements evolve.

[Role]

Two-way technical liaison between large Japanese enterprise customers and our English-speaking engineering organization.

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.

[Two-way liaison]

- To the customer: explain engineering findings, root causes, workarounds, fix timelines, and product constraints in clear Japanese - aligned with what engineering actually intends to deliver.

- To engineering: carry customer environment context, business impact, operational constraints, and requirements in clear English - so fixes and designs reflect real production needs.

- Balance both sides under escalation: set realistic expectations with the customer while giving engineering accurate, reproducible evidence.

- Advocate strongly for the customer: push for timely resolution, clear communication, and outcomes that protect their production environment - without overstating issues to engineering.

[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.

Our mission: make security management easy, reliable, and effective for our customers.

Values: "Being kinder than necessary" | "Learning together" | "Engineering the business" | Celebrating diversity of perspectives

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.

Preferred qualifications

- Prior experience managing Cisco on-prem and cloud security/networking products in production customer environments.

- Large Japanese enterprise accounts (finance, manufacturing, telco).

- Observability stacks (Grafana, Loki, Prometheus or similar).

Summary

A Security Deployment Engineer Technical Leader is an experienced, influential technical leader who bridges customers and

engineering in Japan. You combine deep networking troubleshooting, bilingual precision, strong customer advocacy, and calm

judgment under escalation - keeping both sides aligned on next steps.
