Senior Cloud Engineer I
HybridLondon, England, United Kingdom
Job Summary
Lead design and delivery of large-scale cloud platform projects end to end, from architecture through Terraform to production, ensuring scalability, security, and cost optimization. Act as the Subject Matter Expert for numerous team-owned services, providing advanced operational support and maintaining high availability for global payment systems. Navigate organizational dependencies to optimize delivery speed and business outcomes while evangelizing best practices across the group. Proactively explore and implement AI-driven automation to enhance infrastructure efficiency and team productivity. Manage technical dependencies inside and outside your pillar, balancing delivery speed with business outcomes.
Required Qualifications
- Deep AWS expertise: Advanced, hands-on experience designing and operating production infrastructure in AWS at enterprise scale: multi-account architectures (Control Tower, Organizations, SCPs), IAM, KMS, and the core compute, storage, and security services that a large regulated estate runs on. You should have a proven track record of delivering resilient, multi-region architectures.
- Azure experience: Real production experience with Azure alongside AWS: landing zones, VNet architectures, Entra ID, and the Azure resource and governance model. You understand where the two clouds differ and can design well for both rather than forcing one cloud's patterns onto the other.
- Software engineering mindset: You treat infrastructure as software. Expert-level Terraform: reusable modules, secure state management, and disciplined code review. You are comfortable in a Git-based workflow with CI/CD (we use Spacelift), and you reach for Python or similar to automate what others would handle with a runbook. No ClickOps.
- Strong cloud networking: Confident designing and debugging in a complex network estate: VPC and VNet design, hub-and-spoke and Transit Gateway or Cloud WAN architectures, DNS, private connectivity (PrivateLink, Private Link), and enough routing knowledge to own connectivity issues end to end rather than escalate them.
- Kubernetes: Solid experience running containerised workloads in production, ideally on EKS/AKS: cluster lifecycle, workload deployment patterns, and the operational realities of keeping Kubernetes healthy at scale.
- Experience: 5+ years in cloud engineering roles with significant AWS depth.
- A degree in Computer Science or a related field is useful but not required; we care about what you can build.
Desired Qualifications
- Security and compliance awareness: Experience operating in regulated environments. You understand why change control, least privilege, and auditability matter, and you design controls in rather than bolting them on. Familiarity with PCI DSS is a strong plus.
- Engineering excellence: A focus on observability and measurement: you instrument what you build and answer operational questions with data rather than opinion.
- Leadership and mentorship: A natural ability to guide and mentor peers, translate ambiguous problem definitions into actionable technical plans, and raise the bar through your code and your reviews.
- Pragmatic problem solver: You understand when to move fast (creating tech debt) and when to move right (paying it off). You are a cornerstone in incident resolution and root-cause analysis.
- AI Integration: Proactively explore and implement AI-driven automation to enhance infrastructure efficiency and team productivity.
