The STA partners with product security platform engineering and operations to architect vendoragnostic automationfirst designs that scale across global enterprises.
Key Responsibilities
1) Architecture & Strategy
- Define the network target state (DC Campus WAN/SDWAN Cloud Networking Edge) with reference architectures patterns and standards.
- Create highlevel and lowlevel designs (HLD/LLD) including L2/L3 routing segmentation DNS IPAM firewalling service insertion and observability.
- Establish multicloud network architectures (AWS/GCP/Azure) covering VPC/VNet design Transit Gateways Private Service Connect/Endpoint Direct Connect/Interconnect crosscloud connectivity and service mesh integration.
- Lead modernization from legacy to EVPN/VXLAN fabrics intentbased networking Zero Trust segmentation and SASE/SSE.
- Apply Zero Trust principles across identity-aware segmentation micro/macro segmentation (e.g. SDN NSXT ACI TGW/Cloud WAN firewalls) secure eastwest and northsouth flows.
- Define security guardrails (FWaaS NGFW WAF IDS/IPS DDoS DNS security) key management and policy-as-code; integrate with SIEM/SOAR.
- Partner with the CISO and platform teams to align with NIST CIS ISO 27001 and regulatory standards (e.g. telco/public sector as applicable).
- Engineer for high availability (multiAZ/region fast reroute ECMP anycast graceful restart) and deterministic performance for latencysensitive workloads (including telco and realtime apps).
- Define traffic engineering strategies (QoS/CoS policybased routing segment routing MPLS/EVPN/VXLAN SRMPLS/SRv6).
- Design DR and failover topologies; conduct chaos/resilience testing and capacity planning.
- Drive automationfirst delivery using Terraform/Ansible/Python and network controllers/SDKs; embed policyascode and compliance checks into CI/CD.
- Implement observability: streaming telemetry NetFlow/IPFIX SNMP syslog synthetic testing path analytics digital experience monitoring (DEM).
- Govern SRE practices: SLO/SLI/error budgets for network services; automate pre/postchange validation and rollbacks.
- Architect cloud networking at scale: VPC/VNet design routing domains NAT ingress/egress hybrid connectivity (DX/Interconnect/VPN) service discovery PrivateLink/PSC.
- Integrate Kubernetes networking (CNI Ingress/Egress service mesh like Istio/Cilium) and secure servicetoservice communication.
- Support edge/IoT networking patterns SDBranch and local breakout with unified policy.
- Lead SDWAN strategy and migration from MPLS to internet/5G underlay with applicationaware routing and performance SLAs.
- Define SASE/SSE reference patterns (ZTNA SWG CASB DNS security FWaaS) aligned with identity and device posture.
- Advise executives on network strategy roadmap TCO/ROI and risk.
- Chair Design Authority; review HLD/LLD test plans and change windows; ensure design compliance and nonfunctional requirements (NFRs) are met.
- Mentor architects/engineers; cultivate reusable patterns and accelerators.
Core Networking
- Expert in routing & switching (OSPF BGP ISIS) EVPN/VXLAN MPLS QoS/CoS multicast NAT DNS/DHCP/IPAM.
- Proven experience designing leafspine data center fabrics campus architectures and global WANs.
- Deep knowledge of segmentation (macro/micro) NGFWs IDS/IPS DDoS WAF PKI identitydriven policy and SASE/SSE platforms.
- Handson with policy design across onprem and cloud; integration with SIEM/SOAR.
- Strong with AWS/GCP/Azure networking (VPC/VNet TGW/Cloud WAN PrivateLink/PSC Route 53/Cloud DNS load balancers).
- Familiar with Kubernetes networking (CNIs like Calico/Cilium NetworkPolicies Ingress/Egress service mesh).
- Proficient in Terraform Ansible Python Gitbased workflows CI/CD for network changes compliance checks (e.g. CIS Benchmarks).
- Observability with Prometheus/Grafana App/Net Performance Monitoring NetFlow/IPFIX streaming telemetry.
- Understanding of SRIOV DPDK SCTP 5G core networking concepts UPF placement and deterministic lowlatency patterns.
- Experience with NEF/SEPP security considerations MEC/edge and interconnect with public cloud.
- 12 years in networking with 5 years in architecture leadership roles.
- Certifications (mix of vendor and cloud beneficial): CCNP/CCIE AWS/Azure/GCP networkingfocused certs.
