• Confident technical leadership, stakeholder engagement and communication skills.

About You
You will be a senior engineer or architect, ideally with 10+ years of relevant experience, who combines architectural ownership with hands-on implementation.
You should be comfortable leading complex technical decisions while remaining directly involved in building and delivering solutions. Your experience must include personal responsibility for GitHub Enterprise design and implementation within a large-scale environment.
To apply, please send your CV, availability and a brief overview of your GitHub Enterprise design and implementation experience.
