Jon is VP Engineering, Ubuntu at Canonical, leading the Ubuntu Desktop, Server, Foundations and Debcrafters teams. Prior to this, he spent 4 years leading Canonical's Charm Engineering department focused on a multi-cloud orchestration engine called Juju, the Operator Framework and a number of teams building operators for the world's most popular open source software.

Jon conceived and led the "Oxidizing Ubuntu" initiative which saw Ubuntu 25.10 become the first large-scale Linux distribution to swap out both their coreutils and sudo implementations for modern, Rust-based alternatives from the uutils project and the Trifecta Tech Foundation.

A technical leader by day, and open source contributor and blogger by night, Jon is an active contributor to the NixOS project, and maintains a blog covering his work on Ubuntu, NixOS, pet software projects and home automation at jnsgr.uk.

Linux, open-source and tech interests aside, Jon is a husband and father, a self-professed pour-over coffee connoisseur and mountain biker.
