Job description

We are looking for a Senior Cloud Platform Engineer to design, build and operate the cloud platform that SMG's products run on. The role works in two directions: day to day, you will embed with product squads from discovery to go-live, building the production infrastructure their products need and migrating our remaining AWS workloads into our Azure landing zone. Alongside that, you'll help set the long-term direction of the platform itself: the landing zone, reusable Terraform modules, and the observability and reliability practices that let every squad ship safely without waiting on us. Platform is currently a small, embedded function. We plan to grow it into a dedicated Platform squad, and you'll be one of the engineers who shapes what that squad becomes.

What you'll do

• Own and evolve our Azure landing zone and cloud foundations required for SMG's existing products and future platforms and lead the migration of remaining AWS workloads into it.
• Operate observability and SRE tooling: metrics, tracing and logging. Integrate SMG's chosen observability platform, with clear SLO dashboards, into all products.
• Contribute to the platform roadmap: spot recurring needs across squads and turn them into shared platform capabilities, prioritised with engineering leadership.
• Build the Terraform modules and pipelines that let squads provision and ship into the landing zone safely.
• Security, compliance and cost governance: embed security best practices, participate in audit remediation, manage cloud cost optimisation and tagging/governance.
• Platform networking and identity: design and operate private networking across the landing zone (hub-spoke VNets, private endpoints, private DNS, ingress) and workload identity (managed identities, workload identity federation for pipelines, Entra ID RBAC).
• Embed with product squads from discovery onwards, shaping infrastructure design before it becomes a delivery problem.
• Enable developer self-service and ownership: mentor engineering teams on SRE practices so teams can reliably operate and own their infrastructure.
• Author clear, actionable, version-controlled runbooks, incident playbooks and onboarding guides that enable developer self-service.
  You've designed, built and run production cloud infrastructure for a SaaS product, not just the pipelines that deploy to it.
• Hands-on Azure landing zone experience: management groups, hub-spoke networking, private endpoints and private DNS, Azure Policy, Entra ID/RBAC.
• Hands-on AWS experience sufficient to operate existing workloads and migrate workloads off it
• IaC expertise (Terraform strongly preferred; experience with Bicep / ARM is a plus).
• Pipeline authoring in any mainstream CI tool (we use Azure DevOps and Bitbucket).
• Observability tooling: metrics, tracing and logging stacks and experience translating those into SLIs/SLOs, specifically using Datadog.
• Incident management experience, running on-call and leading blameless postmortems.
• Strong scripting and automation skills; comfortable in at least one programming/scripting language.
• Strong documentation skills.

Desirable

• Certifications: AWS and/or Azure certifications (AZ-305 or AZ-700 especially)
• Azure Landing Zones or the Cloud Adoption Framework
• Container platforms such as ACA or AKS
• Hands-on cloud migration experience
