Senior Software Developer in Montréal

You want to shape how artificial intelligence personalizes travel offers for millions of passengers while spending half your time experimenting with cutting-edge proofs of concept.

What You'll Be Doing

Based in our Montreal office as part of the AI & Merchandising team, you will own the backend application layer that powers our AI-driven pricing and fulfillment products. Your time will be split evenly between shipping production-ready, revenue-generating features and experimenting inside our AI Labs group on new concepts. As part of this work, you help re-engineer software delivery so that AI systems and workflows are integrated directly into our operating model and infrastructure. You will partner with product managers, designers, and engineers to turn ambitious ideas into scalable, high-performance systems.
