Autumn is billing infrastructure for AI companies. Monetization is changing, and we’re work with some of the fastest growing, well-loved, seed-series B startups to power their payments, credit systems and pricing. We also have an active community of indie developers that love and use the product. We have raised $Xm from some of the best founders: Heroku, Convex, Sentry, Supabase, WorkOS, Theo, and Paul Graham etc We’re looking for a backend Founding Engineer who loves to **build**, loves **developers** and has **excellent product taste**. You should have built something in the past and got users for it. You probably want to start your own company one day. You will be our 5th team member. This will be full time, in person in our London office. You will have the option to move to SF too once we establish there. We work a bit harder than your typical 9-5 but you’ll be compensated appropriately for it!
