Summary
🤩
RockstarJoshua Hoblitt is a Staff Storage Engineer with 23 years of experience designing and operating large-scale storage and Kubernetes-based infrastructure from Tucson, Arizona. He led a major migration from GPFS to Ceph and contributed features to the Rook project to enable infrastructure-as-code Ceph deployments, while fleetizing and migrating on-prem workloads to Kubernetes and multiple clouds. Comfortable across DevOps, backend engineering, and test automation, he has practical open-source contributions to prominent projects like Terraform’s Kubernetes provider, Rook, and the Vox Pupuli Puppet modules. Joshua is experienced in automating complex release pipelines spanning 100+ GitHub repos, building observability with Prometheus, and formalizing bare-metal provisioning with Puppet and Foreman. He mentors mid- and junior engineers and combines deep systems-level Unix experience with pragmatic software testing and CI improvements. An owner who’s equally at home coding tests, fixing subtle config bugs, or re-architecting storage for science-grade HPC workloads, he often turns operational pain points into repeatable, automated solutions.
