Job description

Squarepoint is looking for a Platform Storage Specialist to join our growing global team. The candidate will work alongside our team to design, build, and maintain enterprise‑grade storage services that are continuously scaling to support the growth of the company. This role requires in-depth knowledge of distributed storage systems, storage architectures, and storage protocols, including performance optimization, capacity planning, and data lifecycle management. The candidate will ideally have experience with on‑premises storage infrastructure, network‑attached storage, parallel file systems, object storage, and cloud‑based storage platforms. Your day‑to‑day could consist of storage infrastructure design and deployment, performance tuning and troubleshooting, monitoring and alerting improvements, capacity management, automation and tool development, and much more.

Main Duties & Responsibilities

• Design, deploy, and manage distributed storage systems efficiently at scale through standardization, automation, testing, and in‑depth monitoring
• Architect and maintain high‑performance storage solutions including NFS, GPFS, WEKA, and object storage platforms
• Perform storage capacity planning, forecasting, and lifecycle management to ensure optimal utilization and cost efficiency
• Monitor storage performance metrics, identify bottlenecks, and implement tuning and optimization strategies
• Develop and maintain automation tooling for storage provisioning, configuration, and health monitoring
• Collaborate with compute, networking, and application teams to ensure storage solutions meet performance and reliability requirements
• Implement and improve storage‑related observability, alerting, and incident response processes
• Evaluate and integrate new storage technologies, including cloud‑based storage services (AWS S3, EBS, EFS, GCP Cloud Storage, Filestore, etc.)
• Ensure data integrity, availability, and disaster recovery readiness across storage platforms
• Document storage architecture, runbooks, and operational procedures

Required Qualifications

• 5+ years of experience in a technology infrastructure role with a strong focus on storage administration and Linux administration
• Deep expertise with distributed storage systems and storage protocols (NFS, GPFS, WEKA, Lustre, Ceph, or similar)
• Experience with storage performance analysis, benchmarking, and optimization
• Experience working with configuration management driven administration using tools such as Chef or Ansible
• Proficient in Python, or other high‑level language (Go, Rust, etc.) for automation and tooling development
• Experience with modern software development practices: version control, agile development, CI/CD
• Experience with observability in distributed systems (e.g., Elasticsearch, Logstash, Kibana, Datadog, Prometheus, Grafana)
• Experience working with cloud storage services across various cloud providers (AWS and GCP)
• Bachelor's Degree in an Engineering discipline or related area
• Excellent written and verbal communication skills

Preferred Qualifications

• Experience with object storage systems (Cloudian, MinIO, S3‑compatible platforms)
• Familiarity with storage hardware (disk arrays, JBODs, NVMe/SSD technologies, HBAs, and storage networking)
• Experience with data protection strategies including backup, replication, and disaster recovery
• Understanding of storage tiering and data lifecycle policies
• Knowledge of high‑performance computing (HPC) storage workloads and patterns
• Eagerness to continuously learn new storage technologies and develop with us
• Ability to work well in a fast‑paced, adaptable, and pressured environment
