AWS Cloud FSx Admin

About the role

We're looking for a hands-on AWS FSx Storage SME to own the design, deployment, and optimisation of our cloud file storage infrastructure. You'll be the go-to expert for all Amazon FSx product lines — FSx for Windows File Server, FSx for Lustre, FSx for NetApp ONTAP, and FSx for OpenZFS — and will partner with platform, security, and application teams to ensure storage is performant, secure, and cost-efficient at scale.

Key Responsibilities

• Architect, deploy, and manage Amazon FSx file systems across multiple AWS accounts and regions, including multi-AZ and cross-region replication topologies.
• Lead storage capacity planning, performance tuning, and throughput optimization for FSx for Lustre (HPC/ML workloads), FSx for NetApp ONTAP (enterprise NFS/SMB), and FSx for Windows (Active Directory integration).
• Define and enforce storage governance standards — encryption at rest/in-transit, IAM policies, VPC endpoint access, and backup/restore SLAs.
• Automate provisioning, snapshots, and lifecycle management using Terraform/CloudFormation, AWS CLI, and custom Lambda functions.
• Evaluate and implement storage tiering strategies including S3 data repository associations for FSx for Lustre.
• Conduct root cause analysis for storage incidents and drive MTTR improvements through monitoring (CloudWatch, Datadog) and alerting pipelines.
• Act as internal subject matter expert — run enablement sessions, produce runbooks, and support developer teams integrating with FSx endpoints.
• Evaluate AWS FSx roadmap releases and advise on adoption impact for existing workloads.

Technical Skills Required

• 6+ years in cloud infrastructure or storage engineering, with at least 3 years hands-on with AWS FSx services in production environments.
• Deep expertise across two or more FSx variants: FSx for Windows File Server, FSx for Lustre, FSx for NetApp ONTAP, FSx for OpenZFS.
• Strong understanding of NFS, SMB/CIFS, iSCSI, and POSIX file system semantics.
• Proficiency with IaC tools — Terraform or AWS CloudFormation — for storage resource provisioning.
