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 Opportunity This is a rare chance to be at the ground floor of something genuinely new. Pantheon is building the next generation of web content infrastructure: a real-time, collaborative platform that redefines how teams create, publish, and manage content on the modern web. This is a zero-to-one role. The product is early, the architecture is being defined, and the decisions you make will shape how thousands of developers and content teams experience the web for years to come. You will not be maintaining legacy systems or iterating on feature #1001. You will be inventing the foundational layer of a new product
