We’re the original pioneers in connected commerce marketing. Since 2008, we’ve been partnering with major retailers, powering global brands, and building meaningful connections with shoppers.

We simplify the mind-boggling complexity of today’s retail media landscape. We deliver impactful campaigns that connect with people where it matters. We create seamless and personalised shopping experiences. Above all, we deliver amazing results for our partners, driven by our unshakeable desire for growth. Time after time, we change the game. SMG is home to a world-class suite of commerce advertising capabilities powered by data and cutting-edge technology.

We constantly push ourselves, our tech and our industry to discover innovative new ways to connect, sell and grow.

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

As a Senior Dev Ops Engineer you will design, build and operate the platform that powers SMG products and will work as part of a cross-cutting Dev Ops 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.

• Own and evolve Azure cloud foundations: subscriptions, management groups, policies, landing zones, networking (VNETs, peering, hybrid connectivity), and identity (Azure AD / Entra )
• Manage day-to-day Azure operations and be the go-to Azure expert across engineering.
• Support and maintain live AWS infrastructure alongside the existing Dev Ops 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, Git Ops 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 Dev Ops as the primary tool, alongside Bit Bucket 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 Dev Ops and SRE practices. Author clear, actionable, version-controlled runbooks and onboarding guides that enable self-service. Bring Dev Ops thinking into the squads you embed with.

• Proven Dev Ops/SRE experience supporting cloud-based SaaS platforms.
• Working knowledge of AWS and comfort operating in it as a secondary live environment
• CI/CD pipeline authoring:
  Azure Dev Ops, Bit Bucket Pipelines and/or Git Hub 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 Power Shell.
• Strong written communication - clear runbooks, playbooks and documentation.
• Comfortable working across multiple squads with shifting context and priorities.

• Azure certifications (AZ-104, AZ-400 or equivalent).
• AWS certifications.
• Experience with chaos engineering and capacity planning.

We're looking for people who enjoy the buzz of change, the satisfaction of building something better, and the joy of working with a close-knit, values-driven team. If you love variety, thrive in a fast-paced environment, and embrace change with energy, this could be your right role.
