Principal Engineer (Payments Growth & Experience)

Xero reimagined accounting software. Now, we’re reimagining the flow of money itself.

As a Principal Engineer, you will lead the technical strategy for payments growth by designing and building features that directly improve how small businesses manage their money. Your work involves running high-velocity experiments across the full stack to increase product adoption while developing smart, AI-driven capabilities that automate workflows and save customers precious time.

As a technical leader, you will stay close to the code, guiding teams through complex challenges and ensuring best practices across both frontend and backend development. You will spend a significant portion of your time hands-on, writing and reviewing code while partnering closely with product and design leads to solve complex customer problems at scale.

Your impact will be felt through the rapid design and execution of experiments, using data-driven feedback to identify small changes that can result in significant product growth. By building and releasing impactful features, you will directly improve the end-to-end journey for small businesses, specifically focusing on how they get paid.

You will be part of the Payments Growth and Experience team, collaborating closely with product leads and designers to solve real-world problems for millions of small businesses.

You will influence and enable engineering teams across Australia, New Zealand, and North America to conduct effective, data-driven experiments.

The team operates with a hybrid, high-trust culture, connecting through regular workshops to embed experimentation best practices across the portfolio.

You'll also join a global community of Principal Engineers across Xero, driving engineering standards, architecture, and best practices.
