The Opportunity
We are seeking an experienced GCP Cloud Migration Engineer for a high-priority, active lift-and-shift migration. This is a complex brownfield estate migration with a hard contractual datacenter exit deadline.
You will navigate a highly regulated, undocumented legacy environment and transform it into a modern, GCP-native infrastructure. Everything in this environment is auditable, everything is code, and every change is scrutinised. There is zero tolerance for manual console changes or "click-ops."
Responsibilities
• Legacy Migration: Navigate and remediate a complex brownfield estate featuring end-of-life operating systems (Windows Server 2008, older Linux), hardcoded IP addresses, and undocumented server-to-server dependencies.
• Load Balancing Adaptation: Redesign and migrate legacy on-premises load balancing architecture to GCP Cloud Load Balancing (Internal/External models) with zero downtime.
• Infrastructure as Code: Write, maintain, and deploy infrastructure strictly using Terraform within an existing codebase and GitHub Actions CI/CD pipelines.
• Secure Pipeline Management: Operate and troubleshoot pipelines using Workload Identity Federation (WIF) and OIDC token exchange for keyless GCP authentication.
• Security & Compliance: Ensure all architectural changes strictly adhere to HIPAA and PIPEDA frameworks.
• Hybrid Connectivity: Manage active IPsec VPN tunnels between on-premises systems, GCP, and various third-party functional sites.
• AI-Driven Discovery: Leverage AI prompting tools to accelerate current-state understanding, map hidden dependencies, and compress discovery time.
Qualifications
1. Critical Legacy Infrastructure Experience
• Proven track record of working in complex, undocumented brownfield environments.
• Experience handling end-of-life OS, single Active Directory domains spanning prod/non-prod, and unmapped subnets.
• Ability to make sound judgment calls mid-delivery when discovery reveals infrastructure surprises.
2. GCP & Networking Expertise
• Deep knowledge of GCP-native architecture: hub-and-spoke VPC, Cloud VPN, hierarchical firewall policies, IAM, and organisation policy management.
• Strong understanding of GCP URL maps, backend service models, split-horizon DNS, path-based routing patterns, and SSL certificate migration.
3. Terraform & CI/CD Pipelines
• Advanced, hands-on Terraform experience (zero click-ops environment).
• Hands-on experience with GitHub Actions, WIF, and keyless authentication (no service account keys allowed).
4. Security, Compliance & Regulation
• Prior experience working in highly regulated environments under HIPAA and/or PIPEDA frameworks.
• Familiarity with Wiz security scanning (branch level), Wiz CSPM monitoring, and CrowdStrike EDR on workloads.
5. Delivery Under Pressure
• Ability to deliver high-quality infrastructure solutions under tight, contractually mandated datacenter exit deadlines.
