Languages: Bilingual (English/French) Preferred
Employment Type: Full-Time

CGI is seeking an experienced Senior Software Engineering Specialist to join our growing Software Engineering consulting practice within the Emerging Technologies team.

As a full-time member of CGI, you will become part of a collaborative team of architects, developers, and consultants delivering enterprise technology solutions for some of Canada's leading public and private sector organizations. While you may be assigned to one or more client engagements, you will remain a permanent member of CGI's Software Engineering practice, collaborating with teammates, contributing to reusable code assets, and continuously developing your technical and consulting expertise.

In this role, you will help clients design, build, modernize, and scale custom software applications. You will develop robust business logic, design intuitive APIs, and implement modern architectural patterns that improve software quality, user experience, and business agility.

Success in this role requires curiosity, adaptability, strong computer science fundamentals, and a passion for continuous learning. Rather than specializing strictly in a single technology stack, you will leverage sound engineering principles to deliver innovative, scalable, and secure applications across a variety of industries, languages, and client environments.
