A high growth tech business is seeking a Senior Site Reliability & Platform Engineer to help scale its infrastructure and improve developer experience across the organisation.

This is a key role within a modern, cloud native environment where you’ll combine SRE principles (reliability, observability, incident response) with cutting-edge platform engineering (GitOps, IaC, DevSecOps). You'll play a critical part in enabling product teams to ship faster, more securely, and cost effectively - while owning the health and evolution of the platform itself.

Responsibilities:

• Architect and operate scalable, secure infrastructure in Azure (AKS, Functions, SQL, Cosmos DB, etc.)
• Apply SRE best practices: SLOs, alerting, observability, and incident management
• Build and maintain Infrastructure as Code (Terraform, v1.7+) and GitOps workflows
• Enhance CI/CD pipelines (Azure DevOps) with security scanning, automation, and progressive delivery
• Develop reusable tooling, modules, and self-service capabilities for development teams
• Improve monitoring across systems using tools like Datadog, Grafana, ELK, and synthetic checks
• Participate in the on-call rota and lead incident response and post mortems
• 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

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