Senior Cloud Engineer I

Senior Cloud Engineer

Every payment we process runs on infrastructure we built.

At Checkout. com, the Cloud Platform team owns the cloud foundations that global payments depend on: a multi‑account AWS estate, a growing Azure platform, and the networking and connectivity that reaches card schemes and banks worldwide.

We are genuinely multi‑cloud and we are looking for a senior cloud engineer who is a strong generalist who treats infrastructure as a software problem and can deliver from week one.

This is a hands‑on senior role in an established, fast‑moving team.

Everything we run is defined in code, deployed through pipelines, and reviewed like software.

You bring deep cloud expertise across AWS and Azure and pair it with a genuine software engineering mindset: you write Terraform modules others build on, you automate away toil rather than documenting it, and you treat the platform as a product with users, SLOs, and a roadmap.

As a Senior Cloud Engineer, you are responsible for the technical delivery of your team's services.

You will work closely with your Engineering Manager to shape direction, manage dependencies across pillars, and ensure our platform meets the standards a regulated payments business demands.

What we are looking for

• Deep AWS expertise: Advanced, hands‑on experience designing and operating production infrastructure in AWS at enterprise scale, including multi‑account architectures (Control Tower, Organizations, SCPs), IAM, KMS, and core compute, storage, and security services.

Proven track record of resilient, multi‑region architectures.

• Azure experience: Real production experience with Azure alongside AWS, including landing zones, VNet architectures, Entra ID, and Azure resource and governance model.

Understands differences between the two clouds and can design well for both.

• Software engineering mindset: Treat infrastructure as software; expert‑level

Terraform: reusable modules, secure state management, and disciplined code review.

Comfortable in a Git‑based workflow with CI/CD (we use Spacelift) and automates with Python or similar.

No Click Ops.

• 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 (Private Link, Private Link), and enough routing knowledge to own connectivity issues end to end.
• Kubernetes: Solid experience running containerised workloads in production, ideally on EKS/AKS, including cluster lifecycle, workload deployment patterns, and operational realities of keeping Kubernetes healthy at scale.
• Security and compliance awareness: Experience operating in regulated environments, understanding change control, least privilege, auditability, and designing controls in rather than bolting them on.

Familiarity with PCI DSS is a strong plus.

• Engineering excellence: Focus on observability and measurement, instrumenting what is built and answering operational questions with data rather than opinion.
• Leadership and mentorship: Natural ability to guide and mentor peers, translate ambiguous problem definitions into actionable technical plans, and raise the bar through code and reviews.
• Pragmatic problem‑solver: Understanding when to move fast and when to pay off technical debt. Cornerstone in incident resolution and root‑cause analysis.
• Experience: Five or more years in cloud engineering roles with significant AWS depth. A degree in Computer Science or related field is useful but not required.

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 builds on, making the secure path 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 and spread best practices and standards across your group.
• Manage dependencies: Navigate the organisation to manage technical dependencies inside and outside your pillar, optimising delivery speed and business outcomes.
• Foster culture: Embody Checkout Operating Principles, using them to shape the group’s culture and act as an example of efficiency and professional excellence.
• AI integration: Proactively explore and implement AI‑driven automation to enhance infrastructure efficiency and team productivity.
