OpenStack Engineer w Poland, Kraków

At Grape Up, we build Cloudboostr – an EU sovereign open cloud foundation purpose‑built for enterprise AI workloads. Cloudboostr integrates a production‑grade OpenStack private cloud infrastructure, a Kubernetes runtime layer, and an AI governance and orchestration layer into a single platform built entirely on upstream open‑source components.

As a OpenStack Engineer , you will be a core member of the Cloudboostr product team, developing the private cloud infrastructure layer that underpins everything else and deploying it in customer data centers and EU‑based cloud environments across Europe.

Responsibilities

• Design, deploy, and operate enterprise‑grade OpenStack environments as part of the Cloudboostr platform
• Build and maintain automated infrastructure provisioning, upgrade, and backup pipelines using Terraform and Ansible
• Ensure high availability, resilience, and performance of private cloud infrastructure across on‑premises and EU‑based deployment models
• Implement and maintain network architectures and network security policies
• Collaborate closely with the product team to ensure seamless integration between the Cloudboostr’s infrastructure, runtime and AI layers
• Participate in incident response, root cause analysis, and continuous improvement of infrastructure reliability
• Contribute to the evolution of Cloudboostr’s infrastructure architecture – your insights feed directly into the product roadmap
