Back-end Engineer (Node.js, Typescript)
Confirmed on the employer's own hiring board on Nov 14, 2026. First seen by Alion on Jun 3, 2026. signageOS scores B on the Alion truth index.
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 platformenables 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 200,000+ 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 technologythat 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 other software companies rely on - not just another business application.
Real distributed systems
