Platform Engineer (Developer Experience)

At signageOS , we build a platform that powers digital signage networks around the world. Our software runs on thousands of devices across different hardware vendors and operating systems , helping customers manage large-scale display networks from a single platform. We operate at the intersection of cloud, edge computing, and real-world devices deployed in the field. Behind the product are multiple engineering teams and dozens of developers. We’re looking for a Platform Engineer with a strong Developer Experience mindset , who will improve the tools, environments, and automation that our teams rely on every day to build software. Your customers will be our developers Your job will be to remove friction from the development process and improve the environment in which our engineers work. This is not a traditional DevOps role focused primarily on infrastructure operations. You’ll own the internal platform, CI/CD, developer tooling, automation, and systems that help engineering teams build, test, and ship software more efficiently . What You’ll Work On Improving GitLab CI/CD pipelines and related tooling. Making development environments more reliable and easier to work with. Automating repetitive processes and manual tasks. Managing system upgrades and security updates. Building internal tools and services for engineering teams. Creating CLI utilities, dashboards, and self-service interfaces. Removing technical blockers and reducing day-to-day friction for developers. Examples of Problems You’ll Solve Pipelines take longer than they should and slow down feedback loops. Builds or tests fail intermittently without an obvious root cause. Development environments are difficult to set up or maintain. Manual steps exist where automation should. Teams are missing tools that would save them time. Developers lack visibility into the systems they use every day. Things technically work, but create unnecessary friction that adds up over time. How You’ll Know You’re Successful Developers spend less time waiting and more time building. New projects and environments come online faster. Fewer processes require manual intervention. Builds, tests, and deployments become more reliable. Teams encounter fewer blockers. Problems get solved systematically instead of repeatedly. What We’re Looking For You likely come from a background in : Platform Engineering DevOps Site Reliability Engineering Backend Engineering with infrastructure experience Developer Experience We’re not looking for expertise in a specific tool, but someone who enjoys improving systems, understands root causes, and builds solutions that last. Technology You’ll Work With AWS and GCP Terraform Kubernetes GitLab CI/CD Docker and Linux Node.js and TypeScript We see AI as a practical part of modern engineering. If you already use tools like ChatGPT, Claude, Cursor, or similar assistants to accelerate your work, automate workflows, or build internal tools, you’ll fit right in. Why This Role Matters Your work will impact dozens of developers and the entire engineering organization. You’ll build internal platforms and tooling, not just manage infrastructure. You’ll have significant autonomy in deciding what should be improved and how. You’ll work on challenges spanning cloud infrastructure, edge computing, and devices deployed around the world. Practical Information Modern office in Prague 6 (Evropská 11) Hybrid setup (we prefer at least 3 days per week in the office) Office parking available Snacks, drinks, and a comfortable space to work and collaborate Full-time employment or freelance contract Start date by agreement If your idea of a good day is making dozens of engineers more productive than they were yesterday, let’s talk. Send us your CV, LinkedIn profile, GitHub account, or anything else that helps us understand what you’ve built, improved, and are proud of.
