Public Cloud Senior Infrastructure Engineer

At Lloyds Banking Group, we’re building secure, resilient and scalable cloud platforms that power critical services for millions of customers.

We’re modernising at pace—creating engineering-led platforms that are easy to consume, secure by design, and operate at enterprise scale.

We’re hiring two Senior Public Cloud Infrastructure Engineers to join our Google Cloud / GKE Platform team. This is a hands-on engineering role focused on building and operating large-scale Kubernetes platforms in a regulated environment.

You’ll work on a multi-tenant Google Kubernetes Engine (GKE) platform, solving complex platform challenges across automation, security, observability and reliability.

Key responsibilities

Platform Engineering (GKE)

• 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)

Automation & DevOps

• 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

Reliability & SRE

• 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

Security & Compliance

• 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

Networking & Platform Services

• 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)

Essential skills & experience

• Strong experience in Platform Engineering, DevOps or SRE
• 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)
  • Storage patterns
• 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

Desirable experience

• Advanced GKE operational expertise (node pools, upgrades, scaling, security boundaries)
• Experience operating platforms at scale (multi-cluster, multi-tenant)
• Service mesh experience (e.g. Istio, mTLS, traffic management)
• Experience with policy-as-code (OPA Gatekeeper, Config Sync)
• Experience in regulated or compliance-heavy environments
• Strong focus on SRE and platform reliability improvements

Nice to have

• Experience with Backstage or self-service platform tooling
• Familiarity with Anthos Config Management / Config Sync
• Exposure to tools such as CoreDNS, cert-manager, Dynatrace, Cloudability, Infoblox
• Understanding of platform scaling challenges (ephemeral storage, workload density, resilience)
• Experience working with cloud providers on platform architecture

Why join us

• Work on enterprise-scale Kubernetes platforms used by millions
• Influence cloud platform strategy across the Group
• Solve real-world challenges in scale, reliability and security
• Build automation that improves developer experience and reduces toil
• Join a team that values engineering excellence, ownership and innovation

What we offer

• Performance bonus
• Generous pension
• Flexible benefits package
• Private healthcare
• 30 days holiday + bank holidays
• Share schemes
