Key Responsibilities:

  • Design, develop, and maintain a robust automated testing framework from the ground up that supports distributed AI training and inference workloads.

Required Skills and Qualifications:

  • Strong proficiency in Python (for automation and orchestration).

  • Proven experience building or extending test automation frameworks for complex back-end systems.

  • Proven ability to troubleshoot automated test failures within complex large-scale distributed systems, and identify root causes.

  • Experience with containerization (Docker/Kubernetes) and modern CI/CD tools (GitHub Actions, GitLab CI, or Jenkins).

Desired Skills:

  • Experience with Kubernetes or Terraform or Ansible for managing test-bed environments.

  • Experience testing high-performance networking protocols or distributed file systems.

  • Experience testing software that interacts directly with drivers or firmware.

Education:

  • Bachelor's or Master's degree in Computer Engineering, Computer Science, or a related field.

Location:

This is a hybrid role based in Montreal.

Compensation:

Target base salary for this role is $120,000 - $180,000 CAD per year + meaningful equity + benefits + RRSP. Our salary ranges are determined by role, level, experience, and location.

We are an equal opportunity employer. We value a range of perspectives and experiences and make employment decisions based on merit and business needs. We do not discriminate on the basis of legally protected characteristics.
