Original job description

Position Description

CGI is seeking a skilled Python Full Stack Developer to join our growing team and contribute to the development of modern, scalable, and AI-enabled enterprise applications. In this role, you will design, develop, and maintain backend services using Python and FastAPI while building responsive frontend applications using React and modern UI frameworks. You will work with cloud technologies, enterprise databases, REST APIs, and AI integration capabilities, including Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and Model Context Protocol (MCP). Working closely with developers, architects, and business stakeholders, you will deliver secure, high-quality solutions that support digital transformation initiatives.

This is a full-time permanent opportunity based in one of CGI's Atlantic Canada offices, including Halifax, NS; Moncton or Fredericton, NB; St. John's, NL; or Stratford, PEI. Candidates must be currently located in Atlantic Canada or willing to relocate. This role follows a hybrid work model requiring three days per week onsite. The successful candidate must be available to work Mountain Standard Time (MST) business hours.

Your future duties and responsibilities

Design, develop, and maintain scalable backend applications and REST APIs using Python and FastAPI.
Build modern, responsive frontend applications using React, Vite, Tailwind CSS, and Shadcn/ui.
Develop and maintain database integrations using SQLAlchemy, Alembic, PostgreSQL, Oracle, and Databricks.
Integrate AI capabilities into enterprise applications using LLM APIs, RAG, MCP, and AI tools.
Design and implement secure authentication and authorization solutions using OAuth and Microsoft Entra ID.
Apply software architecture principles, including Domain-Driven Design (DDD), SOLID, and enterprise design patterns.
Develop and maintain automated tests using pytest, Vitest, and Playwright to ensure application quality.
Design and support REST APIs, event-driven architectures, and messaging integrations.
Contribute to CI/CD pipelines, containerized deployments, and infrastructure automation using Docker, Kubernetes, GitHub Actions, Azure DevOps, and Terraform or Pulumi.
Collaborate with cross-functional teams throughout the Software Development Life Cycle (SDLC), including design, development, testing, deployment, troubleshooting, and documentation.

Required Qualifications To Be Successful In This Role

Bachelor's degree in Computer Science, Information Technology, Software Development, or a related discipline, or an equivalent combination of education and experience.
Strong hands-on Python development experience, including building backend applications and APIs using FastAPI.
Experience with React and modern frontend development technologies, including JavaScript or TypeScript.
Experience with SQLAlchemy, Alembic, and relational database technologies such as PostgreSQL or Oracle.
Experience with data processing libraries such as Pandas or Polars.
Strong understanding of REST API design, application integrations, and backend architecture.
Familiarity with authentication and security concepts, including OAuth and Microsoft Entra ID.
Experience writing automated tests using pytest and frontend testing tools such as Vitest or Playwright.
Understanding of software design principles, including SOLID, Domain-Driven Design (DDD), and enterprise architecture patterns.
Experience working with Git, CI/CD concepts, and Agile software development practices.
Strong analytical, problem-solving, communication, and collaboration skills.

Assets

The following qualifications would be considered assets:

Experience integrating AI solutions using LLM APIs, RAG, MCP, or AI agent tooling.
Experience with Databricks and enterprise data platforms.
Experience with Redis, message queues, and event-driven architectures.
Experience with Docker, Kubernetes, and GitOps deployment practices.
Experience with Infrastructure as Code tools such as Terraform or Pulumi.
Familiarity with Python development tools such as uv and Ruff.
Experience with GitHub Actions or Azure DevOps pipelines.
Experience developing cloud-native enterprise applications.

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 $55,000–$110,000 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.
