  • Drafting, discussing & implementing technical designs that solve business problems for our customers
  • Lead the ongoing maintenance and support of an existing microservice

  • A strong sense of ownership for your features throughout the SDLC and beyond.
  • Ability to analyse production environments, incidents and performance characteristics
  • Eagerness to improve existing features & systems and plan new ones.
  • As a global company with employees and clients outside of Quebec, fluency in English as a working language is required for this position.
  • Even better if you have hands-on experience with:

  • Continuous integration and deployment of SaaS applications
  • Building microservices and with monolith decomposition
  • Writing automated unit and integration tests
  • AWS as well as Docker & Kubernetes
