Original job description

Position Description

CGI is seeking an experienced Senior Java Developer to join our team and contribute to the design, development, and delivery of high-value payment solutions. In this role, you will develop scalable, high-performance enterprise applications while providing technical leadership across complex initiatives spanning multiple teams and technologies. Working closely with solution architects, developers, business analysts, product owners, QA specialists, and infrastructure teams, you will design secure, resilient, and maintainable software solutions that support mission-critical payment platforms. You will play a key role in driving technical excellence, mentoring team members, and promoting modern engineering practices across the software development lifecycle. This is a full-time permanent opportunity.

Your future duties and responsibilities

Design, develop, and maintain scalable enterprise applications using Java, Spring Boot, and microservices architecture.
Develop secure RESTful APIs and implement authentication and authorization using OAuth and Spring Security.
Design and implement high-throughput, mission-critical applications supporting payment processing and distributed systems.
Build and maintain event-driven solutions using Kafka and messaging technologies.
Develop and optimize relational and NoSQL database solutions, including Oracle, Microsoft SQL Server, and MongoDB.
Collaborate with solution architects and cross-functional teams to design secure, scalable, and resilient software solutions.
Provide technical leadership, code reviews, mentoring, and guidance to development teams.
Support Agile delivery by participating in sprint planning, estimation, architecture discussions, and risk assessment activities.
Contribute to CI/CD practices, application deployment, and continuous improvement initiatives.
Ensure software quality through automated testing, secure coding practices, and engineering best practices.

Required Qualifications To Be Successful In This Role

Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related discipline, or an equivalent combination of education and experience.
Professional software development experience, including significant experience developing enterprise Java applications.
Strong hands-on expertise with Java, Spring Framework, Spring Boot, and Spring Security.
Experience designing and developing RESTful APIs, OAuth authentication, and microservices-based applications.
Experience with event-driven architectures and messaging technologies such as Kafka.
Experience designing and supporting large-scale, high-availability, mission-critical enterprise applications.
Strong experience with relational and NoSQL databases, including Oracle, Microsoft SQL Server, and MongoDB.
Experience with source control and collaboration tools such as Git, Bitbucket, Jira, and Confluence.
Experience working within Agile software development environments.
Ability to decompose complex business requirements into scalable technical solutions.
Excellent analytical, communication, leadership, and stakeholder management skills.
Demonstrated ability to mentor development teams, solve complex technical challenges, and lead technical discussions.

Assets

The following qualifications would be considered assets:

Experience developing front-end applications using React, Angular, or similar frameworks.
Experience with Maven, Jenkins, Nexus, and modern CI/CD pipelines.
Experience with Docker, Kubernetes, or cloud-native application development.
Experience with DevOps practices and infrastructure automation.
Experience with Elasticsearch or AI-assisted development technologies.
Knowledge of network architecture and distributed systems design.
Experience within financial services, payments, or other highly regulated industries.

CGI is providing a reasonable estimate of the pay range for this role. The determination of this range includes factors such as skill set level, geographic market, experience and training, and licenses and certifications. Compensation decisions depend on the facts and circumstances of each case. A reasonable estimate of the current range is $75,000-$115,000 CAD. This role is an existing vacancy.

Together, as owners, let’s turn meaningful insights into action.

Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you’ll reach your full potential because…

You are invited to be an owner from day 1 as we work together to bring our Dream to life. That’s why we call ourselves CGI Partners rather than employees. We benefit from our collective success and actively shape our company’s strategy and direction.

Your work creates value. You’ll develop innovative solutions and build relationships with teammates and clients while accessing global capabilities to scale your ideas, embrace new opportunities, and benefit from expansive industry and technology expertise.

You’ll shape your career by joining a company built to grow and last. You’ll be supported by leaders who care about your health and well-being and provide you with opportunities to deepen your skills and broaden your horizons.

At CGI, we value the strength that diversity brings and are committed to fostering a workplace where everyone belongs. We collaborate with our clients to build more inclusive communities and empower all CGI partners to thrive. As an equal-opportunity employer, being able to perform your best during the recruitment process is important to us. If you require an accommodation, please inform your recruiter.

That same commitment to fairness extends to how we use technology. To support our recruitment team, AI tools may be used to help assess applications though they never replace human judgement. All hiring decisions remain entirely in the hands of our recruitment professionals.
