We are looking for a product-minded Senior Fullstack Engineer to join our API Platform team. In this role, you will design and build the gateway to our entire ecosystem. You will be responsible for the end-to-end journey of external developers and partners-from the moment they read our documentation to their first successful API call in our sandbox, all the way to secure, production-grade integrations.
This is a comprehensive role requiring deep full-stack engineering discipline. You will bridge the gap between frontend user experience (building self-serve developer portals and SDKs) and backend systems engineering (API gateways, security protocols, and high-performance routing).
