- Must be able to successfully complete all client-required background checks, identity verification, and security screening prior to onboarding
Key Responsibilities
- Plan and execute enterprise file and block storage migrations across SAN and NAS environments
- Lead migration activities from discovery and assessment through design, implementation, cutover, validation, and production handoff
- Support EverPure FlashArray and FlashBlade environments, including provisioning, configuration, monitoring, troubleshooting, and lifecycle management
- Migrate file-based workloads using protocols such as NFS, SMB, and CIFS
- Migrate block-based workloads supporting VMware, databases, physical servers, and enterprise applications
- Develop migration plans, technical runbooks, rollback procedures, validation steps, and cutover schedules
- Coordinate migration activities across storage, virtualization, server, network, database, application, security, and vendor teams
- Perform storage provisioning, zoning, host connectivity, multipathing, LUN masking, and datastore configuration
- Validate data integrity, permissions, application connectivity, performance, and availability following migrations

- Support storage replication, snapshots, disaster recovery, and business continuity requirements
- Assist with firmware, software, and hardware lifecycle upgrades
- Monitor storage capacity, latency, throughput, alerts, and overall platform health
- Maintain accurate technical documentation, migration trackers, operational procedures, and environment diagrams
- Participate in change management, incident management, and production-readiness reviews
- Provide clear technical updates to customer stakeholders, project teams, and leadership
