- Participate in the on-call rota and lead incident response and postmortems
- Promote FinOps best practices and cost optimisation strategies
- Contribute to internal platform governance, documentation, and coaching
Experience required - Non negotiables:
- Extensive experience with Azure services, including AKS, Azure Functions, SQL Database, and Cosmos DB
- Proficient in Infrastructure as Code using Terraform (v1.7+)
- Skilled in building and maintaining CI/CD pipelines, GitOps workflows, and automation scripting (PowerShell, Bash)

- Well-versed in DevSecOps methodologies, including security scanning, IAM, and RBAC implementation
- Hands on experience with FinOps practices such as resource tagging, budgeting, and cost optimization
- Proficient in managing both Windows and Linux operating systems
- Confident in supporting production environments, participating in on-call rotations, and collaborating across teams

- Up to £80,000 per annum
- Hybrid / flexible working
- 25 days’ holiday + bank holidays
- Personal development budget
- 35 hour working week
