Your work will help developers build within their existing workflows, understand failures, and confidently depend on Resend as their applications grow.

• Have built software that other developers depend on and understand the responsibility of maintaining it
• Care about interface design, clear errors, useful documentation, and backward compatibility
• Think about agents as users of a product, with their own needs for discovery and security

Responsibilities

• Collaborate with product squads on clear API contracts and consistent behavior across SDKs, CLI, MCP, and documentation
• Build the interfaces developers and agents use to work with Resend, such as MCP, skills, and the CLI

• Build shared tooling that helps other squads ship changes across our developer tools confidently
