GitHub recently turned 17 years old—but how did it start, how has it evolved, and what does the future look like as AI reshapes developer workflows?
In this episode of The Pragmatic Engineer, I’m joined by Thomas Dohmke, CEO of GitHub. Thomas has been a GitHub user for 16 years and an employee for 7. We talk about GitHub’s early architecture, its remote-first operating model, and how the company is navigating AI—from Copilot to agents. We also discuss why GitHub hires junior engineers, how the company handled product-market fit early on, and why being a beloved tool can make shipping harder at times.
Other topics we discuss include:
• How GitHub’s architecture evolved beyond its original Rails monolith
• How GitHub runs as a remote-first company—and why they rarely use email
• GitHub’s rigorous approach to security
• Why GitHub hires junior engineers
• GitHub’s acquisition by Microsoft
• The launch of Copilot and how it’s reshaping software development
• Why GitHub sees AI agents as tools, not a replacement for engineers
• And much more!
