DESCRIPTION

We're seeking a Technical Product Manager to own the roadmap and strategy for the Mailjet API and its core backend capabilities. Partnering closely with the backend engineering team, you'll be responsible for evolving the API in alignment with platform needs, product requirements, and industry standards. Your focus will be on maintaining and extending the API functionality that underpins the entire Mailjet platform, enabling feature development, supporting integrations, and serving customer use cases across both UI and API-based workflows.

As the subject matter expert for the Mailjet API, you'll work closely with engineering, integrations, and customer-facing teams to shape future platform capabilities. This role requires strong technical fluency, systems thinking, and comfort operating on the less visible side of the product, where backend changes and platform decisions quietly power everything customers rely on. You'll also maintain clear and accurate API documentation and coordinate the backend initiatives to ensures the API remains a stable and extensible foundation for the broader Mailjet ecosystem.
