Kastle is building the AI employee for regulated finance. We work with some of America's largest banks and mortgage lenders, helping them scale their contact center and compliance operations using autonomous AI Agents that process payments, originate loans, and help customers get a world class experience during the biggest financial decisions of their lives. We've processed over $2 billion in transactions and are backed by Insight Partners and Y Combinator.

We just raised a $24M Series A and are growing fast!
We're scaling our team 4x over the next year and need a talent leader to build a world class recruiting and people function. We have the basics in place (ATS, HRIS, benefits), but we need someone who can build strategic HR infrastructure, shape our culture, and partner with leadership on talent decisions.
You'll be our first dedicated people leader, evolving our people function from foundational to strategic. You'll own everything from our sourcing and interview process, performance management to compensation frameworks, and employee relations to culture initiatives. You report to the CEO and partner closely with leadership on all people decisions.
