• 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)
• Strong grasp of networking principles, including TCP/IP, load balancing, DNS, and routing
• 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

What You’ll Get:

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

If you're passionate about building scalable, reliable infrastructure and enjoy enabling others through smart platform design — this could be the role for you.
