Role Overview
Serves as the senior network engineer executing s NCC transition.
Leads the design and implementation of Google Cloud Platform network solutions tailored to needs, ensuring risk mitigation and compliance across systems.
Builds the Terraform Infrastructure-as-Code that stands up the NCC hub, spokes, route tables, hybrid attachments, and DMZ insertion; authors the migration runbook; and executes wave-based production cutovers of Shared VPCs, Hub VPCs, and DMZ followed by decommission of the legacy peering mesh.
Key Responsibilities
- Design Terraform module structure and repository scaffolding aligned to existing IaC.
- Develop Terraform for the NCC hub, spokes, route tables, hybrid attachments, and DMZ insertion.
- Build and iteratively test in a mock lab; produce code documentation and READMEs; run code-review cycles and rework with.
- Author the migration Method of Procedure (MOP) a step-by-step runbook plus test/validation plans (routing and application connectivity per step) and rollback procedures.
- Surface pilot-workload dependencies (one non-production workload), plan change windows, and provide pilot execution guidance and advisory during the change window.
- Productionize Terraform (harden, parameterize, environment promotion) and run pre-cutover dry-runs / staging rehearsals per wave.
- Execute BU Shared VPC production cutovers (up to eight production VPCs) in off-hours change windows, supplier-led alongside.
- Support high-risk central events Hub VPC + CCI/Azure cutover and DMZ / Palo Alto egress cutover with post-cutover validation and traffic verification.
- Provide hypercare / stabilization and rollback / war-room standby following each wave.
- Execute legacy VPC Peering decommission and cleanup; deliver as-built documentation and production runbook updates.
Primary Deliverables
- NCC Terraform modules (hub, spokes, route tables, hybrid attachments, DMZ) and mock-lab validation results.
- Migration MOP (step-by-step runbook), test / validation plans, and rollback procedures.
- Pilot execution support and post-pilot lessons-learned report; self-service framework handoff.
- Productionized Terraform and executed cutovers for in-scope BU Shared VPCs, Hub VPCs (CCI/Azure), and DMZ.
- Post-cutover validation and hypercare; legacy VPC Peering decommission; as-built documentation and production runbooks.
Required Qualifications
- Extensive network engineering experience with deep, hands-on Google Cloud Platform networking delivery.
- Expert Terraform / Infrastructure-as-Code for network automation modules, scaffolding, and production hardening.
- Strong hands-on skills across NCC, Shared VPC, VPC Peering, Cloud Router, BGP, route tables, and IPAM.
- Experience with hybrid connectivity (Cloud Interconnect / Cross-Cloud Interconnect to Azure) and DMZ / egress inspection (e.g., Palo Alto).
- Proven execution of production network cutovers in off-hours change windows, including validation, rollback, and hypercare.
- Strong documentation (MOP / runbooks, READMEs, as-builts) and disciplined code review.
Preferred Qualifications
- Google Cloud Professional Cloud Network Engineer certification.
- Direct NCC implementation experience (hub / spokes / route tables / hybrid attachments / DMZ insertion).
- Mock-lab / staging-rehearsal and wave-based migration experience.
- Multi-cloud (Google Cloud Platform Azure) routing and BGP troubleshooting.
- Experience in large, regulated, enterprise-scale (e.g., retail) environments.
Core Technology Environment
Google Cloud networking Network Connectivity Center (NCC), Shared VPC, VPC Peering, Cloud Router, BGP, route tables, IPAM, and Cloud DNS; Cloud Interconnect / Cross-Cloud Interconnect to Azure; DMZ / Palo Alto egress inspection; and Terraform / Infrastructure-as-Code for network automation, including mock-lab validation and wave-based production cutovers.
Engagement Details & Working Arrangement
Delivery model: Dedicated consulting resource supporting NCC Transition workstream the migration of Google Cloud Platform network from a VPC Peering hub-and-spoke topology to a Network Connectivity Center (NCC) fabric.
