Sebastian Jug is a Principal Performance Engineer at Red Hat, where he has worked on Kubernetes and OpenShift performance since 2016. He embraces the frontier where hardware and software meet, tailoring software stacks to the architecture beneath them and pursuing the deep, cross-layer optimization required to realize the full performance of bleeding-edge systems.
His work spans the cloud-native stack, from container runtimes and low-latency systems to edge platforms and accelerated AI. Across that breadth, his approach is grounded in realistic workloads and reproducible results, especially where production Kubernetes makes consistency difficult to achieve. Sebastian has delivered a sustained series of independently audited STAC benchmark submissions on OpenShift across multiple suites and hardware generations, covering CPU and GPU risk analytics as well as low-latency networking. The latest submission extends that work to LLM inference with NVIDIA and Supermicro.
Today, he is exploring how agentic capabilities in the software delivery lifecycle, guided by rigorous benchmarks and evals, can improve application performance. He is a Red Hat Certified Engineer and an experienced industry speaker.
