A hands-on, customer-facing Software Engineer in Japan who troubleshoots security/network issues, advocates for customers, and ensures accurate two-way communication between Japanese enterprises and Cisco's engineering teams.
Software Engineer
Cisco Security Business Group (SBG) is looking for a Software Engineer 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.
Japan-based role. You work from Japan, supporting Japanese enterprise customers in their timezone, with coordination across our English-speaking engineering organization.
Day-to-day two-way liaison for Japanese enterprise accounts. You represent engineering to the customer and the customer to engineering - with strong customer advocacy throughout. You triage issues, coordinate with our English-speaking engineering team, and translate updates Japanese <-> English with technical accuracy on both sides.
- To the customer: relay engineering status, workarounds, and fix guidance in Japanese; help them understand what is happening and what to expect next.
- To engineering: capture customer symptoms, environment details, business impact, and urgency in English; ensure tickets reflect what production actually needs.
- Keep both sides in sync during open escalations - no surprises on either end.
- Advocate for the customer: ensure their impact, urgency, and operational needs are heard clearly by engineering.
- Own L2/L3 troubleshooting on VPN, zero trust access, web inspection in the cloud, CASB, DLP, firewall policy, and AWS/Kubernetes connectivity.
- Collect and analyze logs, packet captures, and metrics; build clear escalation packages for engineering and customer-ready summaries from the same facts.
- Support packet capture and basic packet analysis to narrow IPsec tunnel, IPv4/IPv6, DNS, routing, TLS, and policy-related issues before senior escalation.
- Run scripted health checks (Bash/Python): tunnel/IPsec status, DNS paths, IP pool utilization.
- Capture customer configurations and run daily regression checks to confirm everything is working as intended - surfacing issues before they affect the customer environment.
- Assist upgrades and migrations: pre-checks, smoke tests, rollback planning, and bilingual customer communication.
- Use AI tools to speed up log review - always validate before sharing with customer or engineering.
- Document runbooks, known issues, and customer-specific architecture notes.
- 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.
- 5-7 years in network/security operations, customer support engineering, or professional services.
- Solid TCP/IP (IPv4/IPv6), DNS, routing, NAT, IPsec tunnels, and TLS fundamentals.
- Working knowledge of VPN, zero trust, web inspection in the cloud, CASB, DLP, and firewall policy.
- AWS basics: VPC, subnets, security groups, CloudWatch, hybrid connectivity.
- Kubernetes fundamentals: deployments, services, scaling, basic kubectl troubleshooting.
- Packet capture familiarity (Wireshark/tcpdump) and structured troubleshooting.
- Bash scripting; Python a plus.
- Hands-on experience with Cisco on-prem or cloud security/networking products.
- Prior TAC, PS, or customer engineering role for SASE or enterprise security vendors.
- Observability exposure (Grafana, Loki, Prometheus or similar).
Our mission: make security management easy, reliable, and effective for our customers.
