An Australian travel technology startup is building AI-powered booking tools that make travel planning faster and more personal. They ve closed their seed round, are targeting Series A in about six months, and need a senior applied AI engineer to design and ship the agent systems the product runs on.

What you ll be doing
Designing the architecture for long-running, transactional AI agents
Taking agent features from prototype to reliable production
Making framework and tooling calls with a transparent view of the trade-offs
Building in reliability, observability and failure handling as scale increases




Leaving a solid foundation the team can build on toward Series A

Must Have
Production experience building and shipping LLM agent systems
Deep knowledge of agent frameworks such as LangChain or LangGraph, including how they work underneath
Experience with agents that take real actions or execute transactions
Solid systems and architecture skills at product scale
The ability to be productive from day one with contemporary AI tools
Availability to start at short notice
