Job Description

Senior Software Developer

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.

The Stack

Java (SpringBoot)

AWS
React (TypeScript)
JUnit
Mockito

What You Bring

You build and deploy clean, testable Java code in cloud environments while taking the lead on architecture discussions and technical decisions.
You have structurally changed how your team works around AI by setting shared standards and systems that enable those around you to ship faster without sacrificing quality or safety.
You bring deep computer science fundamentals, from data structures to distributed systems, paired with a disciplined approach to the testing pyramid and delivery pipelines.
You communicate complex technical ideas with clarity, making them accessible to designers, support teams, and fellow developers alike.
You thrive in an Agile environment where you take end-to-end ownership of outcomes, moving quickly without waiting for hand-holding.

Why Plusgrade

Travel is about the moments that make a journey feel personal. At Plusgrade, we build the technology that makes those moments possible, from upgrade offers and loyalty experiences to revenue tools used by 575+ airline, hospitality, cruise, rail, and financial services partners worldwide.

The work is global, complex, and rewarding. You will solve meaningful problems, take ownership from idea to outcome, and work alongside people who are smart, curious, and committed to doing great work.

We also give our teams access to AI tools and the encouragement to use them thoughtfully, to move faster, explore ideas, and build better ways of working.

We trust our teams to do their best work. That means autonomy, flexibility, and room to grow.

Come help us shape the future of travel.
