The Role

Our customers rely on Calendar to run their practice, and were making it faster, smarter, and easier to use. Were looking for an experienced Senior Software Engineer to help lead the development and scaling of Calendar features. Youll own the design and execution of the work you take on, from first idea to production, alongside Product and a team that cares about craft.

• Own the technical design and delivery of complex, user-facing Calendar features across the full stack, from first idea to production

• Advanced, hands-on fluency with AI coding tools like Cursor, Codex, and Claude Code
• High agency. You do your best work when things move fast, and you own quality, reliability, and operational excellence end to end
