Senior Software Engineer – Quinn AI

Quinn AI is seeking a Senior Full Stack Software Developer to help us build the next generation of our AI-powered B2B revenue management platform. You will play a critical role in developing product features end-to-end, from backend APIs to frontend interfaces, while contributing to the technical foundation that will scale with our growing customer base.

This is a high-impact, hands-on role where you’ll work directly with Quinn’s leadership team and experienced engineers, collaborating across product, data science, and design. We're looking for someone who takes ownership, thrives in ambiguity, and is passionate about delivering real value to customers. You’ll help us invent and simplify new ways to manage revenue, shape our engineering culture, and build systems that scale.

Quinn AI is an early-stage startup founded by two former Amazon executives. With strong early traction and paying customers, we are building the Agentic B2B Revenue Advisor – a digital revenue leader that helps B2B companies improve revenue performance through data, automation, and AI.
