Summary
🤩
Rockstar🎓
Top SchoolJed Lejosne is a Principal Software Engineer with over a decade of hands-on experience in virtualization and security, currently driving backend and security features at Red Hat. He began by architecting and maintaining OpenXT, an open-source secure virtualization platform derived from Xen, where he owned root-of-trust, SELinux/XSM integration, USB virtualization and build infrastructure. Transitioning to cloud-native virtualization, Jed has contributed significant security work to KubeVirt—implementing EFI SecureBoot support, strengthening SELinux policies, and adding migration networking features—bringing VM workloads into Kubernetes. His profile blends low-level C/TPM/TXT expertise with modern Go-based cloud engineering, giving him rare end-to-end insight from firmware to orchestrated clusters. An experienced open-source maintainer and team lead, he is comfortable operating across product, research and community boundaries to deliver auditable, secure systems. Based in Medford, MA, he pairs formal low-level engineering training with a track record of productionizing security primitives in both bare-metal and cloud environments.
