🖤💛 Developer Experience Engineer | 200K+ devices. 60+ HW platforms. One ecosystem. 🚀
At signageOS, we build the infrastructure behind digital signage networks around the world – connecting cloud software with real-world devices across different hardware vendors and operating systems.
Behind it are multiple engineering teams and dozens of developers. We’re looking for a senior engineer with a strong Developer Experience mindset to make the way they build, test, and ship software better.
This isn’t a traditional DevOps role focused on production operations. You’ll own improvements to our internal developer platform, tooling, automation, and CI/CD.
Your Mission
Your customers are our developers.
Find where engineering loses time and remove the friction - systematically. You’ll work across teams, identify root causes, set priorities, and own solutions end to end.
The goal isn’t to fix the same problem twice. It’s to build tooling and workflows that make the problem disappear.
What You’ll Work On
Improving GitLab CI/CD pipelines and shortening feedback loops
Making development environments reliable and easy to work with
Eliminating repetitive manual work through automation
Building internal tools, services, CLI utilities, dashboards, and self-service interfaces
Improving visibility into the systems developers depend on
Solving flaky builds, tests, and other recurring engineering bottlenecks
Managing system upgrades and security updates
Every improvement you make is multiplied across dozens of engineers.
Who We’re Looking For
You’ve already spent several years solving these kinds of problems and are comfortable owning them at a senior level.
Your background might include Staff Engineering, Platform Engineering, Developer Experience, DevOps, SRE, or Backend Engineering with strong infrastructure experience.
The title matters less than how you think and what you’ve built. We’re looking for strong technical depth, hands-on experience, systems thinking, and a tendency to solve root causes rather than patch symptoms.
This role is focused on developer productivity and internal engineering systems - not production operations or incident response.
Technology
AWS & GCP · Terraform · Kubernetes · GitLab CI/CD · Docker · Linux
+ Typescript · NodeJS · MongoDB
We actively use GitHub Copilot Workflows, Claude Code, and other AI tools to automate engineering tasks, accelerate development, and build internal tooling. If that’s already part of your toolkit, you’ll fit right in.
Why signageOS?
You’ll work inside an engineering organization building at the intersection of cloud, edge, and real-world hardware.
Your impact is internal but highly leveraged: improve something once, and dozens of engineers benefit every day.
You’ll have the autonomy to identify what needs to change, decide how to solve it, and help shape the technical direction of our developer platform.
