About the role

Key responsibilities & impact
  • Design, develop, and deploy services and REST APIs in C# / .NET, with a constant focus on quality, performance, and maintainability
  • Model and evolve our data on SQL (MySQL / Aurora / PostgreSQL) and NoSQL (DynamoDB), choosing the right tool for the problem
  • Operate a containerized microservices architecture (Docker) deployed on AWS and its managed services (ECS/Lambda, S3, SQS/SNS, RDS, CloudWatch, etc.), with infrastructure managed as code via Terraform
  • Own your code end-to-end: tests, peer review, production deployment via our continuous integration and delivery pipeline (GitHub Actions), and then observability and operations
  • Fully participate in our Agile practice (Scrum): planning, breaking down work, demos and code reviews
  • Raise the level of those around you — share best practices, provide mentoring, and document architectural decisions

Requirements

What you’ll need
  • 10+ years of software development experience in product-oriented companies
  • Deep mastery of C# and the modern .NET ecosystem, with strong experience designing RESTful APIs (plus an asset: GraphQL, gRPC, or event-driven architectures)
  • Excellent understanding of object-oriented design, service- / microservice-oriented architecture, and Clean design principles (Clean Architecture, SOLID)
  • Hands-on experience modeling data on SQL (MySQL / PostgreSQL) and NoSQL (DynamoDB), with the judgement to choose between them
  • Practical proficiency in Python, used in our tooling, data workflows, and AI/ML processes
  • End-to-end experience on AWS: developing, deploying and operating production services
  • Comfortable with Docker, infrastructure as code (Terraform), CI/CD pipelines (GitHub Actions), automated testing (TDD/BDD), and observability (logs, metrics, traces)
  • Proven track record of delivering high-quality software on time, both independently and as part of cross-functional teams
  • Bilingual French / English, spoken and written
  • Knowledge of English is required, as the role involves working with an international team, including Canada, the United Kingdom and the rest of Europe
  • AI and assisted development (essential, not optional)
