About RevenueCat
RevenueCat removes the headaches of building and scaling in-app subscriptions. Since graduating from YC's S18 batch, it has grown into the default monetization platform for mobile — present in over 40% of newly shipped subscription apps, processing $10B+ in annual purchase volume, and helping everyone from solo developers in Brazil to the OpenAI mobile team understand and grow their revenue. The team is remote-first, 120+ people across 25 countries, guided by values they actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance.
About the Role

The ideal candidate is product-focused, customer-focused, and passionate about building mobile SDKs with a great developer experience.
