Senior Infrastructure Engineer, Public Cloud

Jobtailor; Halifax; On-site; GBP 70,000 - 110,000; Full time

Job summary

Jobtailor is seeking an experienced Platform Engineer to design, build and operate scalable GKE environments and engineer multi-tenant Kubernetes clusters with strong isolation and guardrails.

You will support shared and dedicated cluster patterns, automate infrastructure with Terraform, CI/CD and GitOps, and drive improvements in performance, security and reliability across production workloads. You will also participate in on-call rotations and policy-as-code controls.

Qualifications

• Proven delivery of production Kubernetes platforms, ideally GKE.
• Experience with multi-tenant platform environments (shared clusters, isolation, scaling).
• Deep understanding of Kubernetes internals (scheduling, storage, node lifecycle, upgrades).
• Strong knowledge of Google Cloud Platform (GCP), including: GKE IAM / Workload Identity Networking (VPC, DNS, NAT, ingress/egress).
• Experience with Infrastructure as Code (Terraform) using modular design.
• Strong experience with CI/CD pipelines and GitOps workflows.
• Coding/scripting (Python, Go or Bash).
• Strong troubleshooting and problem-solving skills.
• Ability to own and deliver complex engineering outcomes.

Responsibilities

• Design, build and operate scalable, resilient GKE environments.
• Engineer multi-tenant Kubernetes clusters with strong workload isolation and platform guardrails.
• Support shared and dedicated cluster patterns, including tenant onboarding.
• Improve platform performance under production conditions (e.g. scaling, storage, node pressure).
• Build automation-first infrastructure using Terraform, CI/CD and GitOps.
• Simplify cluster lifecycle management (provisioning, upgrades, add-ons).
• Develop self-service platform capabilities to improve developer experience.
• Apply Site Reliability Engineering (SRE) practices to platform operations.
• Support incident response, monitoring, observability and continuous improvement.
• Diagnose issues across performance, scaling, storage and automation.
• Contribute to a 24x7 on-call rotation.
• Implement policy-as-code controls (e.g. OPA Gatekeeper, RBAC, workload identity).
• Support audit, compliance and risk mitigation activities.
• Ensure platforms are secure, supportable and aligned to control frameworks.
• Work with service mesh and ingress/egress patterns (e.g. Istio, Anthos, Cloud Service Mesh).
• Support cloud networking (VPCs, DNS, NAT, VPN, routing, connectivity).
• Integrate shared platform services (cert-manager, observability, cost tooling).
