Summary

Rockstar🎓
Top SchoolThomas Schubart is a pragmatic systems engineer and Member of Technical Staff in the San Francisco Bay Area with 7+ years building cloud-native developer tooling, Kubernetes operators, and AI agent infrastructure. He’s a core open-source contributor—helping lead youki, a Rust container runtime, and authoring oci-spec-rs (12M+ downloads)—which underpins critical container ecosystems. At Ona (formerly Gitpod) he’s shipped latency-optimized agent executors, credential proxies, layered egress defenses, and workspace snapshotting that cut startup times from minutes to seconds. He combines deep systems expertise in Go and Rust with product-minded delivery, improving SaaS reliability to 99.99% and reducing deployment surface and code size through pragmatic redesigns. Notably, he built Construct, an API-first multi-agent AI coding assistant, and designed tooling that safely gives agents access to third-party APIs without exposing secrets. He’s equally comfortable mentoring teams, running on-call incident response, and architecting secure, customer-hosted runner and billing infrastructures.
