Senior Storage Architect (Cloudian S3)

Overview

We are seeking an experienced and motivated Storage Architect to design, build, and evolve object storage services across hybrid environments (on-premises and public cloud). The successful candidate will play a key role in defining and implementing scalable, secure, and high-performance storage architectures, leveraging S3-compatible technologies such as Cloudian, and integrating them with enterprise and cloud-native services. 

Key Responsibilities 

• Architecture & Design: Define the architecture for S3-compatible object storage services supporting both on-prem and cloud-based workloads (AWS, Azure, etc.). 
• Hybrid Storage Strategy: Design solutions that enable seamless integration between datacenter and cloud object storage. 
• Service Implementation: Lead the deployment and configuration of object storage clusters (e.g., Cloudian HyperStore), ensuring availability, durability, and scalability. 
• Automation & Orchestration: Implement Infrastructure-as-Code (IaC) practices using Terraform, Ansible, or equivalent to streamline provisioning and lifecycle management. 
• Monitoring & Optimization: Use tools like HyperIQ or Prometheus/Grafana to monitor usage, detect anomalies, and optimize performance. 
• Security & Compliance: Apply data protection standards, encryption policies, and access control measures aligned with EU regulations and customer expectations. 
• Disaster Recovery: Design and validate backup and DR strategies using object storage features like replication and versioning. 
• Integration Support: Collaborate with development, operations, and infrastructure teams to enable storage consumption via APIs, GitOps pipelines, and Kubernetes platforms. 
• Documentation: Maintain architecture blueprints, SOPs, and operational documentation for service ownership and audit readiness. 

Required Skills & Experience 

• 10+ years in infrastructure or storage architecture with significant hands-on experience in object storage and S3 APIs. 
• Strong understanding of distributed object storage systems (e.g., Cloudian, MinIO, AWS S3). 
• Expertise in hybrid storage design and integration between DC and cloud. 
• Proven experience in designing secure, scalable storage services for large organizations. 
• Solid skills in automation and configuration management (Terraform, Ansible). 
• Experience with container platforms (Kubernetes, Docker) and integrating storage in CI/CD or GitOps pipelines. 
• Monitoring experience with systems like HyperIQ, Prometheus, Grafana, etc. 
• Knowledge of IAM, encryption at rest/in transit, and secure multi-tenant architectures. 
• Excellent communication and documentation skills. 

Preferred Qualifications 

• Experience with Cloudian HyperStore, HyperBalance, and HyperIQ is a strong plus. 
• Familiarity with SAFe Agile practices and cross-team collaboration in scaled agile environments. 
• Experience in performance tuning and capacity planning in high-throughput storage environments. 
• Awareness of EU compliance and data residency requirements. 

Other Requirements 

• ONLY EU citizenship; 
• Fluency in English (written and spoken) is required; proficiency in any other European language is a plus.
• A 5-day onboarding in Luxembourg is necessary, during which the equipment is handed over, and the team and procedures are introduced.
• The position is remote, but you have to be able to handle occasional short on-site appearances in Luxembourg. You have to be ready for this, but it rarely happens in practice.
• Ready to start work without unnecessary delay,
• Ability to obtain security clearance.
