JobsCloseBy Editorial Insights

Marqeta seeks a Senior Technical Writer to craft API and SDK docs that developers can trust, collaborating with Engineering, Product and Design, and leading documentation as a scalable product using docs-as-code, automation and AI. The role emphasizes accuracy, real request and response examples, and aligning code to docs, with the ability to read code and test APIs. Location is Flex First, remote within Ontario or British Columbia, Canada. Key qualifications include 5+ years of developer documentation, OpenAPI or Swagger, REST, JSON, GitHub, Markdown, Postman, and fintech or payments experience. Tips: tailor your resume to highlight API doc pipelines, provide samples with AI assisted updates, quantify impact and onboarding improvements.

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!
