• Lead incident response efforts, coordinating multi-vendor troubleshooting and supporting NOC during major incidents.
• Oversee change and release management, assessing the impact of updates and policy changes.
• Communicate effectively with NOC, security teams, and management, providing clear technical explanations.

As a successful Secure Access & Networking Architect, you will have:

• Deep hands-on expertise with Cisco Secure Access (formerly Cisco+ Secure Connect/ZTNA).
• Strong understanding of coexistence with Cisco AnyConnect VPN and Zscaler Internet Access.
• Advanced endpoint troubleshooting skills (Windows): network drivers, tunnel adapters, certificate stores, DNS resolution, and client logs.
• In-depth knowledge of Cisco Application Connectors and deployment models.
• Solid networking fundamentals: TCP/IP, DNS, proxying, TLS/SSL, NAT, routing, and Firewall behaviour in hybrid environments (on-prem + AWS).
• Identity and access management expertise: SAML/OIDC, MFA, certificate-based authentication, and role-based access policies.
• Security troubleshooting skills: traffic inspection, policy enforcement validation, and attack surface reduction.
• Strong communication skills for technical and non-technical audiences.
