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.

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.
