Senior SRE

The role

You will design and maintain safe deployment patterns and cloud infrastructure for WPP's systems. You will work on monitoring, incident response and automation across GKE, Terraform and CI/CD.

What you will do

• Design and maintain safe deployment patterns (blue-green, canary, progressive delivery) using ArgoCD and Kargo.
• Instrument logs, metrics, traces and alerts; define SLIs and SLOs with service owners.
• Tune and troubleshoot GKE workloads, including autoscaling, node pools, network policies and resource limits.
• Build and maintain reusable Terraform modules for core infrastructure.
• Lead or support incident response, run blameless postmortems and drive long-term fixes.
• Detect and eliminate configuration drift; standardize secrets handling and short-lived credentials.
• Automate operational toil with Python and shell scripting and harden CI/CD pipelines.

Required qualifications

• 4–6+ years of experience in backend or infra-focused engineering roles, with at least 2 years owning production systems at scale.
• Ability to write or review production-grade code and infrastructure-as-code (Terraform, Helm, GitHub Actions).
• Deep hands-on Kubernetes experience in production, ideally GKE, including autoscaling, ingress/gateway strategies and network policies.
• Solid GCP fundamentals (IAM, VPC design, Workload Identity, Secret Manager, CloudSQL) and experience with at least one major cloud (AWS, Azure or GCP).
• Understanding of cascading failure, timeout boundaries, dependency health and blast radius.
• Regular contribution to incident mitigation or long-term fixes.
• Ability to influence through well-written PRs, documentation and design reviews.
• Hands-on experience with Cloudflare or a comparable edge/CDN/WAF platform.

Nice to have

• Experience with Kargo or similar progressive promotion tooling (Argo Rollouts, Flagger).
• Experience developing or integrating Kubernetes operators.
• Familiarity with SLIs, SLOs and structured alerting.

Before you apply

• Candidates may not have every listed skill; applying is encouraged with a strong foundation and willingness to learn.
