## About the Role

* Experience with distributed, cloud-native systems. Payments experience is a bonus, not a requirement.
 * Experience building something from zero to one: a product, a platform, a team or a company
 * Comfort with ambiguity and with making decisions on imperfect information
 * Recent Kotlin or Java experience. An interest in Rust is a plus.
 * Low ego: confident enough to hold an opinion and humble enough to change it
