Job Description

Wells Fargo is seeking a Micro-segmentation Senior Information Security Engineer. We are looking for a solid security engineer with a technical foundation in firewalls and traffic segmentation. Ideal candidates would have hands on segmentation experience with Illumio and at least one of: Guardicore (Akamai), VMware NSX-T, Cisco Secure Workload, or Kubernetes-native (Calico/Cilium, NetworkPolicies) including policy simulation/shadow testing and staged rollouts. Hands-on segmentation in hybrid environments (on‑prem + AWS/Azure/GCP), including Azure ASG/NSG or AWS SG patterns, and Kubernetes/Service Mesh (NetworkPolicies, mTLS, Istio/Envoy) for east‑west traffic would be highly desirable. Scripting is a talent of yours and you like the challenge of building reliable automations using Python/PowerShell, Terraform/Ansible, and ServiceNow IntegrationHub with OAuth2/OIDC-secured APIs, version control (Git/GitHub), CI/CD, and policy-as-code workflows (idempotent, retry-safe). Security is top of mind for you and you are able to implement identity- and risk-aware policies by integrating CMDB labels, workload identities, and EDR/PAM context to enforce Zero Trust segmentation

  • Utilize subject matter knowledge in industry leading security solutions and best practices to implement components of information security
  • Collaborate and provide influence with all members of the microsegmentation team
  • Define and coordinate automation strategies to integrate micro-segmentation with CMDB and user-facing portals, translating business and security requirements into actionable deliverables for development teams

Requirements

  • 4+ years of Information Security Engineering experience, or equivalent demonstrated through one or a combination of the following: work experience, training, military experience, education
  • Experience with Micro-Segmentation security solutions including policy management
  • Experience with scripting
  • Strong understanding of APIs and proficiency in working with JSON, including the ability to interpret, construct, and troubleshoot queries and payloads in support of automation and integration efforts
  • Experience with one or more: Guardicore (Akamai), VMware NSX T, Cisco Secure Workload, Calico/Cilium
  • Experience with Hybrid cloud segmentation in Azure/AWS/GCP (NSG/ASG, SG/NACL, tags/labels)
  • Experience with Service Mesh (Istio/Envoy), Kubernetes NetworkPolicies, OPA/Gatekeeper
  • Scripting skills such as Python/PowerShell, Terraform/Ansible, Git/GitHub, CI/CD
  • ServiceNow IntegrationHub
  • Telemetry (NetFlow/IPFIX/eBPF, VPC Flow Logs) and SIEM analytics (Splunk/Sentinel/Elastic
  • KQL/SPL)
  • Understanding of NIST 800 207 Zero Trust and mapping to NIST/CIS controls
  • Experience designing policy simulation/shadow testing and staged rollouts with measurable KPIs
