Role Description Marqeta is seeking a Senior Product Manager for SDKs, Developer Platform & Documentation to lead the strategy and evolution of the developer platform that powers how customers build on Marqeta. You will own the end-to-end developer experience across Mobile and Web SDKs, APIs, and documentation, ensuring developers can easily discover, integrate, test, and scale financial capabilities. - Your scope includes iOS, Android, and Web SDKs; API platforms; developer tooling; authentication and identity; developer portals; onboarding flows; sandbox environments; and documentation systems. - You’ll partner closely with Engineering, Developer Relations, Documentation, Security, Design, and Solutions Engineering, as well as directly with customers, to deliver a platform that is intuitive, reliable, and scalable. - This role requires strong technical fluency and product judgment to improve developer experience, reduce integration time, and drive platform adoption. - The developer platform is how Marqeta scales. SDKs, APIs, and documentation determine how quickly customers build and launch. - Strong developer experience reduces integration time, increases adoption, and drives growth. - This role removes friction, accelerates time-to-production, and makes Marqeta the platform developers choose first. We work Flexible First. This role can be performed remotely anywhere within Ontario, Canada. We’d love for you to join us! This position is for an existing vacancy. Qualifications - 5-8+ years building products developers love — proven track record shipping SDKs, APIs, or developer platforms that scale and delight technical audiences. - Deep technical fluency across modern ecosystems — strong working knowledge of mobile (iOS/Android), web frameworks, and API-first architectures that power today's digital experiences. - SDK and API expertise — hands-on experience with SDK architecture, lifecycle management, and crafting intuitive APIs that developers actually want to integrate. - Developer experience obsessed — proven ability to improve onboarding flows, enhance API usability, and create documentation that turns complexity into clarity. - External developer engagement — experience building for and collaborating with external developer communities, including partnerships with DevRel teams to drive adoption and advocacy. - Data-driven platform growth — track record scaling developer platforms using metrics that matter: adoption rates, time-to-first-hello-world, API error rates, and developer satisfaction. - Fintech or infrastructure platform experience — bonus points for payments expertise (mobile wallets like Apple Pay/Google Pay) or building mission-critical infrastructure that powers other products. - Innovation mindset — experience applying AI/automation to streamline developer workflows, reduce friction, and unlock new capabilities that weren't possible before. Requirements - Own the roadmap for Mobile and Web SDKs (iOS, Android, Web), including scalability, performance, and usability. - Lead developer documentation strategy across API references, guides, and onboarding experiences. - Improve developer onboarding, API usability, and integration workflows. - Partner with engineering on SDK lifecycle management (releases, versioning, compatibility, performance, security). - Build tooling and environments (sandbox, testing, debugging) to accelerate integration and developer productivity. - Drive SDK and platform adoption by reducing complexity and improving developer experience. - Enable modern payment experiences, including mobile wallet integrations (Apple Pay, Google Pay). - Collaborate across Developer Relations, Documentation, Support, and Solutions Engineering. - Leverage AI to improve developer workflows (documentation generation, troubleshooting, API discovery, code examples). Nice-To-Haves - Owned end-to-end developer journeys. - Experience with design systems tied to SDKs. - Experience driving platform standardization. - Experience with developer observability/debugging tools. - Experience across enterprise and self-serve developers. - Track record improving time-to-first-call or time-to-production.
