We strive for the perfect balance of simplicity and excellence in everything we do, and we’re looking for people who are ready to join our journey and rewrite the story of data sovereignty.
Role overview
We’re looking for a Senior Platform Engineer to join our Engineering team and take a lead role in building and operating the infrastructure that underpins our products and services. You’ll focus on delivering secure, reliable, and scalable platforms, with a strong emphasis on OpenStack, to support our sovereign cloud strategy and meet customer expectations.

•Drive adoption of Infrastructure-as-Code (Terraform, Ansible) and GitOps practices across infrastructure operations.
•Lead automation of infrastructure provisioning, configuration management, and system maintenance processes.
•Own observability across the platform — logging, monitoring, alerting, and performance tuning.
•Collaborate with network, security, product, and operations teams to deliver integrated, production-ready infrastructure.
•Evaluate and maintain platform components to ensure they meet performance, compliance, and availability standards.
•Conduct architectural reviews, lead incident response retrospectives, and drive continuous improvements in system reliability.
