The role and its impact

This is a senior individual contributor and technical leadership role at the heart of one of Xero’s most strategically important initiatives.

As Principal Engineer for Platform API, you will define and drive the long-term technical vision for how Xero exposes its accounting capabilities to external partners (building on our platform) and to internal product teams who depend on a stable, well-designed API layer to move fast.

The decisions you make here will shape how millions of small businesses and their advisors experience Xero, not just through our own products, but through the ecosystem of applications and agents built around them.

Beyond the external surface, this role sits at the intersection of platform engineering and AI. The APIs you design and steward will serve as the trusted foundation for AI- and agent-driven automation across Xero’s accounting workflows; meaning you will be thinking not just about today’s developer experience, but about what it means for an LLM or autonomous agent to safely read, write, and orchestrate complex financial workflows. It is a rare opportunity to do genuinely consequential technical work at scale.
