Introducing the Infrastructure Engineering and Tooling team aka Atlas at Trainline

Atlas owns the ecosystem used to deploy, run and manage traffic to the Trainline platform. We’re currently building the next generation of our infrastructure platform. We use a variety of technologies — from Terraform to Node.js, C#, Python and AWS — and we focus on software engineering excellence: reliability, quality, automation, and fast iteration.

The team is split into two squads, each with a mix of software engineers, platform engineers and cloud specialists, supported by Engineering Managers and a Head of Engineering who shapes our strategy alongside a Technical Product Manager.

You won’t just be “managing systems” — you’ll be building the code-driven foundations that hundreds of engineers use daily. This is the perfect role if you’re a software engineer who’s passionate about applying coding skills to the world of cloud-native engineering.

As a Cloud Engineer at Trainline you will...

• Join a high-performing, inclusive team where you can inspire people and own results.

• Work on transforming Trainline into a cloud-native organisation by building opinionated platform solutions through clean, testable, production-quality code.

• Use Infrastructure as Code (Terraform/OpenTofu) and modern programming languages to create scalable, maintainable systems.

• Improve developer experience so product teams can ship features faster and more reliably.

• Contribute to process improvements and platform evolution, iterating along the way.

Qualifications

We'd love to hear from you if you...

• Have solid experience in at least one modern programming language (e.g. Node.js, Python, C#) and can confidently read, write, and discuss code.

• Strong DevOps or infrastructure experience is valuable, but this role requires hands-on coding ability. A coding exercise is part of the interview process.

• Understand software engineering principles: version control, modular design, testing practices such as TDD.

• Consider yourself reliable, transparent and collaborative.

• Have knowledge of cloud computing, ideally AWS.

• Enjoy working with Infrastructure as Code (Terraform/OpenTofu) and automation tools.

• Have a basic understanding of Linux.

• Are curious and eager to learn new languages, frameworks and cloud technologies.

• Node.js and Typescript

• Terraform and Spacelift

• Containers / Serverless
