OpenStack Engineer

About the Position

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 an 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

Requirements

• 3+ years of hands-on experience deploying and operating OpenStack in production environments
• Deep understanding of core OpenStack services
• Experience with Ceph for distributed storage
• Strong knowledge of Linux (Ubuntu preferred) system administration and networking fundamentals
• Experience with infrastructure-as-code using Terraform and configuration management (Ansible)
• Familiarity with CI/CD concepts and pipeline tooling
• Understanding of cloud security principles: network segmentation, IAM, secrets management
• Strong problem-solving skills and ability to operate independently in a product-oriented engineering team

Nice to Have

• Experience with Kubernetes and understanding of how OpenStack and Kubernetes interoperate
• Experience operating OpenStack at scale across multiple physical sites or regions
• Experience setting up and configuring GPU-enabled nodes in OpenStack
• Openness to (short, occasional) Business Trips, both domestic and foreign

We Offer

• Locations: Białystok, Kraków, Wrocław, or Remote
• Salary: 18 000 - 25 000 PLN net (B2B)
