Senior Software Development Engineer, Annapurna ML Systems, Trainium

Sr. Software Development EngineerWe're seeking a Sr. Software Development Engineer with deep storage expertise to architect, build, and operate the high-performance storage infrastructure that accelerates silicon development at Annapurna Labs. In this role, you'll own the storage platforms—spanning Amazon FSx for NetApp ONTAP, FSx for Lustre, and S3—that enable chip design teams to iterate faster, run regressions more efficiently, and bring transformative custom silicon to market.Key job responsibilities include designing, deploying, and operating high-performance storage platforms—Amazon FSx for NetApp ONTAP (Gen1/Gen2) and FSx for Lustre—optimized for EDA and HPC workloads. This includes managing NFS exports, ONTAP SVMs, intelligent tiering (FabricPool), snapshot policies, SnapMirror replication, and quota enforcement across multi-tenant environments. You'll deploy all storage infrastructure using AWS CDK, architect cross-VPC and multi-account solutions via Transit Gateway and Route 53 private hosted zones, enable EFA for high-throughput Lustre access, and manage data synchronization using DataSync and S3 integrations.You'll build a Storage as a Service platform with self-service provisioning, defined SLOs, cost attribution, and automated lifecycle management that enables teams to consume storage without deep specialization. You will build monitoring and observability for storage health, utilization, and cost trends, and establish incident response processes for storage-related failures. You'll continuously evaluate and adopt new AWS storage features—Gen2 scale-out, NVMe-over-TCP, enhanced backup performance—to keep the platform at the leading edge. You'll profile I/O patterns across EDA workloads, tune file system configurations for optimal performance, and partner with silicon design and verification teams to proactively scale capacity and mentor others on storage best practices.A day in the life might start your day reviewing storage utilization dashboards and tiering efficiency reports, identifying file systems approaching capacity thresholds or workloads that would benefit from tier migration. Mid-morning, you could be collaborating with a verification team to provision a new FSx for Lustre file system optimized for their regression suite—sizing it based on their I/O profiles, enabling EFA access, and deploying it through your CDK pipeline.In the afternoon, you might be building the next iteration of your Storage as a Service platform—adding automated quota enforcement for a new team onboarding, implementing a snapshot policy that aligns with their project milestones, or extending cross-VPC access to a new account. You'll review pull requests for CDK constructs, investigate a DataSync job that stalled, and discuss FSx ONTAP Gen2 migration plans with your team. Throughout the day, you'll balance immediate customer needs—expanding a volume for a team blocked on disk space, troubleshooting NFS mount latency—with longer-term platform investments like evaluating intelligent tiering policies or prototyping NVMe-over-TCP access patterns. You'll engage with AWS service teams on feature requests and roadmap alignment, ensuring Annapurna Labs gets the most from the storage platform.At Annapurna Labs, your storage infrastructure work directly enables breakthrough innovations in custom silicon that power AWS and transform industries. The EDA Cloud Infrastructure team builds and operates the compute, storage, and networking platforms that hundreds of chip designers and verification engineers depend on daily. We offer the resources and scale of AWS with the innovation culture and technical depth of a focused silicon team.If you're passionate about storage systems, thrive on building platforms that make complex infrastructure simple for others, and want to see your work accelerate the next generation of AWS silicon—we want to hear from you.
