Integrate automated testing into GitLab CI/CD pipelines and quality gates.
Execute and troubleshoot automation in containerized and Kubernetes environments.
Manage test execution, reporting, and defect tracking using Jira and Zephyr.
Collaborate with developers and DevOps teams to diagnose and resolve complex system issues.
Mentor junior and intermediate test engineers through coaching, code reviews, and technical guidance.
Assist with test planning, work assignment, prioritization, and delivery coordination across the test team.

Education and Experience required

6-9 years of related experience in Test Automation
Strong Python development and automation experience.
Advanced experience with Pytest and automated testing frameworks.
Hands-on experience with Selenium-based UI automation.
Experience testing REST APIs, microservices, and distributed systems.
Experience with Kafka or similar event-driven messaging platforms.
Experience with GitLab, CI/CD pipelines, and source control best practices.
Experience using Jira and Zephyr for test management and defect tracking.
Proven ability to mentor engineers and lead automation initiatives.
Strong analytical, troubleshooting, communication, and collaboration skills.
Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or a related field, or equivalent practical experience.

Nice to have

Experience with Trino, HTTPX, gRPC, or Kubernetes.
Exposure to Prometheus, Grafana, OpenTelemetry, or distributed tracing.
Experience in telecommunications, SDN, cloud-native platforms, or large-scale distributed systems.
Experience working in AI-assisted software development environments.

The successful candidate must be able to work in Canada and obtain clearance under the Canadian Controlled Goods Program (CGP).
