Devops Engineer(openshift+GCP+Harness)

Senior DevOps Engineer

Manchester, UK | Hybrid | Full-time

ROLE PURPOSE Build and evolve secure, resilient cloud platforms and delivery capabilities that enable engineering teams to release software faster, safely and consistently. This is a hands-on role spanning Kubernetes engineering, infrastructure automation, continuous delivery, observability and platform controls.

What you will do

Design, build and operate enterprise Kubernetes platforms using GKE and OpenShift, including cluster lifecycle, networking, ingress and workload security.

Create reusable platform services, golden paths and developer self-service capabilities through Backstage and Internal Developer Platform patterns.

Build secure, repeatable cloud environments and reusable modules using Terraform and Infrastructure as Code principles.

Design and maintain continuous delivery pipelines using Harness and Jenkins, with source control and collaboration through GitHub / Git.

Implement end-to-end observability using Dynatrace, covering metrics, logs, traces, telemetry, dashboards, alerting and service health.

Define SLI/SLO measures and automate operational runbooks, remediation and repeatable support activities to reduce manual effort.

Engineer service-to-service connectivity and controls using Istio Service Mesh, including traffic management, ingress/egress and policy enforcement.

Manage secrets, certificates and workload identity securely using HashiCorp Vault and automated certificate lifecycle practices.

Embed platform controls, least-privilege access, secure configuration, resilience and auditability into engineering patterns.

Partner with product, engineering, architecture, security and operations teams; coach colleagues and promote platform adoption and engineering standards.
