Your mission :
Overview
We are seeking an experienced and motivated S3 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.
Your profile :
Required Skills & Experience
- 10+ years in infrastructure or storage architecture with significant hands-on experience in object storage and S3 APIs.

- 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.
