🖤💛 Backend Engineer | Build Infrastructure, Not Another SaaS 🚀

Most software companies build applications.

We build the infrastructure powering digital signage around the world.

There’s a good chance you’ve already encountered technology powered by signageOS—in McDonald’s, Starbucks, 7-Eleven, airports, retail stores, office buildings, and many other places globally.

Our hardware-agnostic platform enables customers to deploy, manage, monitor, and scale digital signage across dozens of hardware vendors, operating systems, and device types—all through a single cloud platform and unified API.

Today, signageOS powers more then 100,000 connected devices across 60+ hardware platforms with 99.99% platform availability.

Build once. Deploy anywhere.

For our customers, that’s the promise. For our engineers, making it possible is the challenge.

Why this role is different

Most backend engineering jobs are about building business applications.

This one isn’t.

You’ll build the technology that hides the complexity of dozens of hardware vendors, operating systems, firmware versions, and unreliable networks behind a single developer experience.

That means dealing with:

• devices that go offline unexpectedly
• different hardware vendors implementing things differently
• firmware inconsistencies
• communication over unreliable networks
• remote diagnostics and monitoring
• systems that have to recover gracefully without human intervention

These aren’t edge cases. They’re the product.

What you’ll work on

Your work will include:

• Backend-first, building core platform services primarily with TypeScript and Node.js.
• Distributed systems handling asynchronous communication between cloud services and physical devices over unreliable networks.
• Platform architecture and shared capabilities that abstract dozens of hardware platforms behind a single developer experience.
• Reliability at scale, making infrastructure resilient when things inevitably go wrong.

While you’ll occasionally contribute across the stack, this is fundamentally a backend engineering role focused on the infrastructure everything else depends on.

Why engineers join signageOS

Infrastructure, not CRUD

Build technology that other software companies build on—not another business application.

Real distributed systems

Work on cloud services coordinating more than 100,000 physical devices operating across the world.

Engineering over process

Small, experienced team with minimal bureaucracy and fast technical decision-making.

Own technical decisions

We expect engineers to shape architecture, challenge ideas, and propose better solutions—not simply implement tickets.

Problems worth solving

From hardware abstraction and distributed systems to device communication, observability, cloud infrastructure, performance, reliability, and automation, every project brings a different engineering challenge.

Your code ships to production environments used by customers worldwide.

Our stack

TypeScript · Node.js · PostgreSQL · GraphQL · Kubernetes · AWS · GCP · React / Next.js

We actively use GitHub Copilot Workflows, Claude Code, and other AI tools to automate workflows, accelerate iteration, and eliminate repetitive engineering work.
