🖤💛 Cloud Engineer | Beyond SaaS. Cloud powering 100,000+ connected devices worldwide. 🚀

Build the cloud behind enterprise digital signage

signageOS powers digital signage in places you already know: including McDonald’s, Starbucks, 
7-Eleven, airports, retail stores and office buildings around the world.

Our hardware-agnostic platform helps global brands deploy, manage, monitor and scale their digital signage across:

• 100,000+ connected real-world devices
• 60+ hardware platforms
• dozens of operating systems and device types
• one unified cloud platform and API
• 99.99% platform availability

Build once. Deploy anywhere.

That’s the promise we make to our customers - and the engineering challenge - you’ll help us solve.

Cloud is part of the product

At signageOS, cloud infrastructure isn’t just a background service. It directly shapes the reliability, scalability and performance our customers experience.

You’ll work closely with engineering to design, build and evolve the cloud infrastructure behind signageOS. Your focus will be to ensure it:

• scales with our customers,
• stays secure and reliable,
• remains cost-efficient as we grow,
• and enables engineers to build and ship effectively.

We’re looking for someone who doesn’t just keep systems running.

You notice what’s slowing the team down, solve problems before they become bottlenecks and help engineering make better architectural decisions for the long term.

This role is for you if…

You don’t wait for change, you drive it. 

You see what needs to improve and make it happen.

You’ve built production systems and know that good engineering is about understanding trade-offs, not chasing perfect solutions.

You care about outcomes, not just implementations.

Complexity doesn’t impress you. Simplicity, automation and measurable impact do.

Where you’ll make an impact

• Define and evolve the architecture of our cloud infrastructure.
• Build infrastructure across AWS, Google Cloud Platform and Kubernetes.
• Drive Infrastructure as Code with Terraform.
• Keep our services scalable, secure, observable and easy to operate.
• Keep cloud costs under control as we grow.
• Automate repetitive work wherever it still exists.
• Work with Redis, RabbitMQ, cloud-native services and carefully selected open-source technologies.
• Help ensure our infrastructure scales with both our customers and the growing number of connected devices.
• Explore how AI can improve engineering productivity and DevOps workflows.
