There's an exciting road ahead of us, where travel needs real, impactful change. With offices in New Zealand, Australia, North America, and China, we are thrilled to be expanding our global footprint, landing our new hub in Bengaluru, India. With rapid a growth plan in place for India, we’re hiring people from different backgrounds, experiences, abilities, and perspectives to help us build a world-class team and product. We're building a greenfield AI-native travel booking product designed specifically for the US market—an intent-driven conversational experience that transforms natural language into policy-compliant, bookable trips. This is a rare opportunity to define architecture and engineering standards for a new AI product from near-zero, operating with startup pace and autonomy while backed by an ASX-listed company with substantial resources.

You’ll have meaningful autonomy—to define both what we build and how we build it.
