• Bachelor's, Master's, or PhD degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience).


• 8+ years of professional engineering experience in storage systems engineering or infrastructure platforms.


• Strong hands-on experience with object storage or distributed filesystems in high-scale production environments.


• Deep experience with storage protocols (e.g., S3, NFS) and distributed architectures such as Ceph, DAOS, or similar.


• Proficiency in a systems programming language such as Go, C, or Rust.


• Experience working with cloud-native infrastructure, Kubernetes, and scalable system architectures.


• Familiarity with storage observability, metrics collection, and telemetry pipelines (e.g., ClickHouse, Prometheus, Grafana).


• Proficiency leveraging AI tools to augment and accelerate software development workflows.
