Senior Software Engineer - Storage Control Plane

About the Position

We are looking for an experienced Senior Software Engineer to join our storage team. You'll join a team responsible for developing and implementing our next-generation storage software. This role requires expertise in distributed systems, and an in-depth understanding of file, block, and object storage protocols. You'll work on building scalable and resilient storage control plane that power our AI and machine learning infrastructure.

Responsibilities

• Design and build a vendor-agnostic control plane that provisions, scales, heals, and meters storage across the platforms our customers actually demand, VAST Data, WEKA, DDN, Pure, NetApp, Ceph, MinIO, and the ones that don't exist yet.
• Define the internal abstraction layer that hides vendor-specific APIs, failure semantics, QoS knobs, and telemetry formats behind one declarative interface, so a new vendor integration is a driver, not a re-architecture.
• Build reconciliation-loop and CRD-based orchestration (Kubernetes controllers, operators, custom schedulers) that manages capacity, tenancy, encryption domains, and placement across data centers and availability zones.
• Own multi-tenant isolation end to end: namespace and subsystem partitioning, per-tenant QoS and rate limiting, credential and key lifecycle, blast-radius containment, noisy-neighbor detection.
• Design the capacity and placement engine: PCIe-topology-aware, NUMA-aware, failure-domain-aware. On our platforms a drive behind the same PCIe switch as the GPU it serves beats a faster drive on a different root port, and the control plane needs to know that.
• Instrument everything: SLI/SLO definitions, fleet-wide performance regression detection, and the observability pipeline that makes a petabyte fleet debuggable at 3 a.m.

Requirements

• Bachelor's or Master's degree in Computer Science or a related field.
• 5+ years of experience in software development for storage systems.
• Proven experience with distributed systems programming and concepts such as load balancers, data-durability, consensus algorithms, fault tolerance, and data consistency.
• Strong programming skills in languages such as C, C++, Go, or Python.
• Experience with Linux kernel internals and system-level programming.
• Experience with one or more storage protocols (e.g. S3, NFS) and file systems such as Ceph, DAOS, or similar.
• Familiarity with containerization technologies like Docker and Kubernetes and running production workloads in these environments.
• Familiarity with CI/CD and QA practices for distributed systems development environments.

Nice to Have

• Experience with AI/ML workloads and the unique storage challenges they present.
• Knowledge of data center networking and high-speed interconnects (e.g., InfiniBand, RoCE).
• Experience with performance tuning and optimization of storage systems.
• Familiarity with hardware acceleration technologies, specifically GPUs and DPUs.
• Production experience with VAST Data, WEKA, DDN, Pure, NetApp, or IBM Storage Scale.
• Ceph at 100 PB+ in HPC or AI environments.
• CXL memory pooling, computational storage, ZNS SSDs, EDSFF.
• Published or presented at SNIA SDC, FAST, USENIX ATC, LSFMM+BPF, OCP, SC, or similar.

We Offer

• Competitive salary range: $266K - $395K
• Health, dental, and vision coverage for you and your dependents
• Wellness and commuter stipends for select roles
• 401k Plan with 2% company match (USA employees)
• Flexible paid time off plan that we all actually use
