About Pantheon Pantheon brings together exceptional builders who take ownership, drive meaningful impact, and shape what's next for the web. We power more than 300,000 websites globally for organizations including Google, Princeton, Salesloft, Clorox, and the United Nations. Every day, thousands of developers and marketers use our WebOps platform to build, iterate, and scale WordPress, Drupal, and Next.js sites that reach billions of people worldwide. As an employer, we operate with the same philosophy that drives our product: foundation and freedom. Pantheon is a vibrant, remote-forward team of experts who care deeply about their craft and results. Here, you take ownership of work that matters, contribute alongside exceptional people, and see the impact you create. The Role Pantheon is seeking a Principal Engineer to join our Internal Platform team — the group responsible for the tools, platforms, and practices that make Pantheon’s own engineers more effective. You’ll shape how engineers across the company write, test, deploy, and operate software: from CI/CD pipelines and internal developer portals to AI-assisted workflows, developer productivity metrics, and self-service tooling. We’re looking for someone who has built internal developer platforms or developer experience programs at scale — at a software company, developer tools company, or platform engineering team — and who brings AI-native instincts to the work. At Pantheon, AI isn’t a feature we’re adding — it’s how we work. You’ll bring the same rigor to our internal engineering systems that we bring to the platform we sell, and you’ll be a force multiplier across every engineering team. What You Need to Succeed Define and drive the technical roadmap for Pantheon’s internal developer platform, including self-service tooling, CI/CD infrastructure, and developer enablement programs that reduce friction across the engineering organization. Architect, build, and evolve core developer experience systems — including internal developer portals, standardized service templates, observability tooling, and AI-assisted development workflows. Define and own Pantheon’s developer productivity metrics strategy — selecting and evolving frameworks (DORA, SPACE) to measure engineering effectiveness, and translating insights into clear recommendations for engineering leadership. Partner with engineering teams to identify high-friction areas in the software delivery lifecycle and design iterative, high-impact solutions that measurably improve developer flow and satisfaction. Lead adoption of AI-powered developer tooling across the engineering organization — evaluating tools, establishing standards, measuring impact, and driving cultural change toward AI-first workflows. Provide technical leadership across the engineering organization — setting direction, reviewing designs, and raising the bar for quality, reliability, and developer experience. Mentor and coach engineers at all levels, providing technical guidance and growing engineering talent across the broader organization. Contribute to an engineering-wide culture of collaboration, continuous improvement, and developer empathy.
