Senior DevOps Engineer

We are looking for a Senior DevOps Engineer to join our Engineering Team.

As a Senior DevOps Engineer you will design, build and operate the platform that powers SMG products and will work as part of a cross-cutting DevOps function that embeds directly into product engineering squads. Azure is our primary cloud and the core focus of this role.

You will lead Azure platform setup, cloud foundations, and day-to-day operations, while also supporting and integrating with live AWS infrastructure, which remains in active use as a secondary environment, as well as partnering with engineering teams to deliver a reliable, observable, secure, and cost-effective platform that enables safe, repeatable delivery across all cloud environments. What you’ll do

• Own and evolve Azure cloud foundations: subscriptions, management groups, policies, landing zones, networking (VNETs, peering, hybrid connectivity), and identity (Azure AD / Entra ID)
• Manage day-to-day Azure operations and be the go-to Azure expert across engineering.
• Support and maintain live AWS infrastructure alongside the existing DevOps Engineers. AWS remains an active secondary environment. You will need to be comfortable operating in it even though Azure is your primary focus.
• Write and maintain IaC using Terraform for Azure-native resources. Build automation, GitOps patterns, and self-service platform tooling that enables development teams to provision and operate infrastructure reliably.
• Design, build and maintain CI/CD pipelines using Azure DevOps as the primary tool, alongside BitBucket Pipelines where in use.
• Operate our observability stack (Datadog) across all environments. Define and maintain SLOs, SLI dashboards, incident response runbooks and playbooks. Lead blameless postmortems and on-call processes.
• Embed security best practices into platform and pipeline design. Participate in audit remediation, manage cloud cost optimisation, and enforce tagging and governance standards across Azure and AWS environments.
• Mentor engineering teams on DevOps and SRE practices. Author clear, actionable, version-controlled runbooks and onboarding guides that enable self-service. Bring DevOps thinking into the squads you embed with.

• Proven DevOps/SRE experience supporting cloud-based SaaS platforms.
• Hands-on Azure expertise: subscriptions, Azure AD/Entra ID, VNETs, Azure Monitor, Azure DevOps. Azure certification is strongly preferred.
• Working knowledge of AWS and comfort operating in it as a secondary live environment
• IaC expertise: Terraform (primary); Bicep/ARM.
• CI/CD pipeline authoring: Azure DevOps, BitBucket Pipelines and/or GitHub Actions.
• Observability tooling: Datadog - metrics, tracing, logging, and SLI/SLO definition.
• Incident management: comfortable running on-call and leading blameless postmortems.
• Strong scripting and automation skills: Python, Bash, or PowerShell.
• Strong written communication - clear runbooks, playbooks and documentation.
• Comfortable working across multiple squads with shifting context and priorities.

Nice to have

• Azure certifications (AZ-104, AZ-400 or equivalent).
• AWS certifications.
• Experience with chaos engineering and capacity planning.
• Platform engineering experience: developer portals, golden paths, self-service infrastructure.
