checkout.com - Senior Cloud Engineer I

• 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. • 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. • Experience: 5+ years in cloud engineering roles with significant AWS depth. We need someone who can hit the ground running: comfortable joining a complex, established estate and delivering meaningful work in their first weeks, not their first quarter. A degree in Computer Science or a related field is useful but not required; we care about what you can build. • HOW YOU’LL MAKE AN IMPACT: • Lead Design & Delivery: Take ownership of large-scale platform projects end to end, from architecture through Terraform to production, ensuring they are scalable, secure, and cost-optimised. • Build the paved road: Design the platform primitives that every product team at Checkout.com http://Checkout.com builds on, so that the secure path is also the easy path. • Architectural Influence: Work with Engineering Managers and architects to refine requirements and shape the technical direction of the platform, documenting significant decisions as ADRs. • Operational SME: Act as the Subject Matter Expert for numerous team-owned services, providing advanced operational support and ensuring high availability for our global payment systems. • Evangelise Best Practices: Produce exemplary code and documentation that inspires others. You will be responsible for spreading best practices and standards across your group. • Manage Dependencies: Navigate the organisation to manage technical dependencies inside and outside your pillar, optimising for both delivery speed and business outcomes. • Foster Culture: Embody Checkout Operating Principles, using them to shape the group’s culture and acting as an example of efficiency and professional excellence. • AI Integration: Proactively explore and implement AI-driven automation to enhance infrastructure efficiency and team productivity. • It’s important we set you up for success and make our process as accessible as possible.
