AI Native Senior Full Stack Engineer

RevOS is a bootstrapped, entrepreneurially run German startup founded and funded by serial founders. We’re building a revenue intelligence platform that helps B2B companies turn fragmented go-to-market data into a single, trusted foundation for AI-powered analytics and automated action. Our platform gives revenue teams early visibility into churn risk, pipeline slippage, and expansion opportunities — so growth becomes predictable, not reactive. Today, we work with exceptional customers across Europe who rely on RevOS to make better, faster revenue decisions. We're looking for a AI Native Senior Full Stack Engineer who is self-driven, opinionated about good engineering, and excited to make a real impact.
