Location: St. Louis
- Design and deploy enterprise firewall rule sets across data centers, cloud platforms, and edge environments, including zone-based segmentation and micro segmentation policies to minimize attack surface.
- Conduct rule reviews, cleanup initiatives, and policy rationalization efforts to eliminate redundancy and reduce complexity.
- Develop and maintain workflows for rule provisioning, validation, and decommissioning using automation tools (e.g., Ansible, Terraform, Python) and integrate them with ITSM systems (e.g., Service Now) and CI/CD pipelines.
- Implement policy-as-code frameworks to standardize rule creation, change control, and compliance monitoring across on-prem and cloud environments.
- Design and manage firewall policies for AWS, Azure, and GCP, implement transit gateway/hub-and-spoke architectures, and align network security with cloud governance models.
- Provide tactical response for critical global incidents, codify lessons learned into reusable playbooks, and translate outcomes into enduring standards.
- Conduct network consulting engagements, produce reference architectures, define structured solutions (HLD, LLD, BoM, QA), emphasize Infrastructure-as-Code and observability, and map as-is to to-be states with prioritized remediation plans.
- Support the creation, refinement, and validation of firewall policies used for both production and lab deployments.
- Assist in reviewing and aligning firewall rulesets to updated segmentation strategies defined during design phases.
- Contribute to policy updates and validations required for migration of DMZ workloads to new fabrics.
- Support testing activities—including baseline traffic verification and resiliency checks—from a policy governance perspective.
- Assist in maintaining policy documentation, contributing to knowledge transfer, and supporting post-migration cleanup of legacy rules.
