Sybill | Senior Software Engineer (Backend)

About the Company: At Sybill.ai, we're building the next evolution in B2B sales - an AI-first platform that transforms how sellers work. Think of it as your intelligent sales IDE (Integrated Deal Environment), empowering sellers to focus on what truly matters: building relationships and closing deals. Today, sellers spend 70% of their time on non-revenue activities. We're flipping this paradigm on its head. Sybill's AI lets sellers become super-performers who guide AI systems and focus on high-impact customer interactions. Our proprietary AI technology, developed by a small but mighty team from Stanford, Harvard, and the IITs, and backed by leading investors in Silicon Valley, is not just another tool; it serves as the foundation of a groundbreaking sales workflow that delivers exceptional outcomes for our users. With 99%+ retention and 20x growth to $1.2M ARR last year, our customers' enthusiasm speaks for itself.Who Thrives at Sybill?
