Senior Developer Experience Engineer, Integrations

Responsibilities

• Build and evolve Customer.io's SDKs across platforms - including Android, iOS, Node, and Go - and the developer tools that support them
• Lead SDK initiatives end to end: set technical direction, write the code, manage the release, and own the outcome
• Improve SDK delivery infrastructure - CI, automated testing, versioning, publishing, and release processes - so shipping is reliable and low-friction
• Partner closely with product and design to turn loosely defined goals into a great developer experience
• Participate in an on-call rotation as required, supporting the reliability of the systems you build
• Use AI agents to make multi-file changes across unfamiliar codebases and languages by scoping the work, writing the prompt, and verifying the output
• Bring strong customer empathy to the role - understanding what the engineers integrating with our SDKs actually need, and occasionally engaging directly with them
