Senior Cloud Engineer I in London

We’re Checkout.com. You might not know our name, but companies like eBay, Spotify, Klarna, Uber, and Sony do, because we’re behind many of the digital experiences you use every day. We are where the world checks out, enabling over 10 billion transactions yearly for more than one billion global shoppers. Our platform helps the most ambitious businesses deliver effortless digital experiences, at scale.

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 large 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 too - 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 will bring deep cloud expertise across AWS and Azure and pair it with a genuine software engineering mindset.

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.
• Azure experience: Real production experience with Azure alongside AWS.
• Software engineering mindset: You treat infrastructure as software.
• Expert-level Terraform: reusable modules, secure state management, and disciplined code review.
• Strong cloud networking: Confident designing and debugging in a complex network estate.
• Kubernetes: Solid experience running containerised workloads in production.
• Security and compliance awareness: Experience operating in regulated environments.
• Engineering excellence: A focus on observability and measurement.
• Leadership and mentorship: A natural ability to guide and mentor peers.
• Pragmatic problem solver: You understand when to move fast and when to move right.
• Experience: 5+ years in cloud engineering roles with significant AWS depth.

How you’ll make an impact:

• Lead Design & Delivery: Take ownership of large-scale platform projects end to end.
• Build the paved road: Design the platform primitives that every product team at Checkout.com builds on.
• Architectural Influence: Work with Engineering Managers and architects to refine requirements.
• Operational SME: Act as the Subject Matter Expert for numerous team-owned services.
• Evangelise Best Practices: Produce exemplary code and documentation that inspires others.
• Manage Dependencies: Navigate the organisation to manage technical dependencies.
• Foster Culture: Embody Checkout Operating Principles.
• AI Integration: Proactively explore and implement AI-driven automation.

We create the conditions for high performers to thrive, through real ownership, fewer blockers, and work that makes a difference from day one. Here, you’ll move fast, take on meaningful challenges, and be recognized for the impact you deliver.

Our hybrid working model offers flexibility, with three days per week in the office to support collaboration and connection.
