180K+ connected devices. 50+ hardware platforms. 80+ partners. 99.99% availability.
At signageOS, cloud infrastructure isn't just something running in the background. It's a critical part of how our product works.
Your challenge? Keep it reliable as we scale, without losing sight of performance, security or cost.
You'll work hands-on with AWS, GCP and Kubernetes, combining cloud-native services with open-source technologies. You'll also help shape architecture decisions, working directly with our CTO, Tech Leads and Senior Cloud Architect.
What you'll work on
Cloud architecture: Design and improve our AWS and GCP infrastructure, integrating cloud-native services with open-source technologies.
Reliability & scaling: Improve observability, troubleshoot production issues and prepare our infrastructure for a growing number of connected devices, while keeping performance and costs in check.
Infrastructure automation: Use Kubernetes, Terraform and CI/CD to improve deployments, automate routine operations and make infrastructure easier to manage.
Security & maintenance: Work on vulnerability management, automated penetration testing, intrusion detection and attack prevention, alongside regular upgrades, security patching and SOC 2 compliance.
AI-driven operations: Explore agent-based automation for infrastructure management, security testing and autonomous issue resolution.
On-call: After onboarding, join a four-person L2 rotation, typically one week per month, with additional compensation. This includes responding to production incidents, cloud provider outages and security threats.
Here's where it gets interesting
Infrastructure is part of the product. The cloud platform you work on supports digital signage operations worldwide. Its reliability directly affects the services our customers depend on.
Cloud meets unpredictable hardware. Different operating systems, inconsistent firmware and unreliable networks mean infrastructure decisions must account for devices that can disconnect without warning.
A say in what comes next. You'll work directly with our CTO, Tech Leads and Senior Cloud Architect on technology choices and infrastructure design, with room to explore more autonomous ways of managing operations.
Who would thrive here
Strong hands-on experience with AWS or GCP in production, with in-depth knowledge of at least one.
Practical production experience with Kubernetes and Terraform - not just personal projects.
Experience with CI/CD, infrastructure automation, monitoring and troubleshooting.
A solid understanding of cloud security, scalability and infrastructure costs.
The ability to work independently, take responsibility for production systems and make sound technical decisions.
Nice to have: Multi-cloud experience, Redis / Dragonfly, RabbitMQ, database operations, developer tooling or an interest in AI-assisted infrastructure automation.
You don't need to know every technology we use. What matters is your experience with production systems and how you approach technical problems.
