Senior Technical Writer

As Marqeta’s Senior Technical Writer, you will shape how developers build on our platform by creating and scaling documentation for APIs, SDKs, and platform experiences. Our documentation is a core product surface and often the first interface that developers encounter, so it must clearly reflect the system's actual behavior. This role goes beyond writing. You will improve how documentation is structured, generated, and maintained at scale using tooling, automation, and AI, while driving clarity, usability, and self-serve integration. You will partner closely with Product, Engineering, and Design as part of a collaborative team that treats documentation as a critical part of the developer experience.

We work Flexible First. This role can be performed remotely anywhere within Ontario or British Columbia, Canada. We’d love for you to join us!
