Full Stack Engineer

About Letter AI Letter AI is the world's first unified revenue acceleration platform powered natively by generative AI. Our platform empowers sales teams at customers like Lenovo and Redpanda to ramp up faster with AI-powered training and coaching, instantly find and personalize collateral for customers, and engage their buyers with the industry's first AI Sales Room. We recently raised a $40M Series B led by Battery Ventures, with participation from existing investors including Y Combinator, Lightbank, Northwestern Mutual Future Ventures, Stage 2 Capital, and Formus. The round comes just four months after announcing our Series A, indicating a shift we're seeing in real time: revenue teams aren’t asking for more content or tools. They’re asking for better outcomes, and Letter AI is bringing those outcomes to life! We 10Xed our revenue last year and are looking for the best of the best in the Bay Area to join us on the adventure 📈.
