Responsibilities
- Design, develop, maintain, and document production-grade Python automation frameworks, reusable packages, fixtures, command-line tools, test utilities, and supporting services.
- Use AI-assisted development tools for coding, refactoring, test generation, debugging, analysis, and documentation while reviewing outputs for correctness, security, maintainability, and licensing risk.
- Design automated tests with Pytest and develop or extend plugins for execution, reporting, retries, logging, test selection, resource coordination, environment management, and CI result publication.
- Develop, integrate, and validate REST APIs and gRPC services, including streaming patterns.
- Automate distributed, event-driven microservices and asynchronous workflows using Azure Service Bus and Azure Blob Storage.
- Create functional, integration, component, contract, system, regression, reliability, resilience, performance, and scalability automation.
- Validate distributed-system behaviors including eventual consistency, partial failure, timeouts, retries, duplicate delivery, backpressure, concurrency, and recovery.
- Integrate tests, reports, logs, artifacts, environment controls, and quality gates into GitLab CI/CD and GitLab Runner environments.
- Package and execute automation in containers and deploy, inspect, diagnose, and troubleshoot tests and microservices running on Kubernetes.
- Improve test repeatability through deterministic data, configuration management, environment isolation, structured logging, metrics, traces, and actionable diagnostics.
- Read existing Java code and create or modify small Java scripts or utilities when required.
- Participate in code reviews, technical design discussions, engineering standards, documentation, and peer knowledge sharing as a senior individual contributor.
Requirements
- Strong hands-on Python development experience covering object-oriented design, typing, packaging, dependency management, concurrency or asynchronous programming, error handling, logging, and framework architecture.
- Demonstrated experience designing and implementing substantial automation frameworks and engineering tooling rather than only individual test cases.
- Deep understanding of Pytest architecture, collection and execution lifecycle, fixtures, parametrization, hooks, configuration, plugin development, and plugin ecosystems.
- Practical experience using AI-powered development tools with disciplined human review and validation of generated code and tests.
- Working knowledge of Java sufficient to read production code and write or modify small scripts and utilities.
- Experience developing, integrating, or testing REST APIs and gRPC services, including streaming patterns and distributed failure modes.
- Experience automating asynchronous messaging and object-storage workflows using Azure Service Bus and/or Azure Blob Storage or comparable technologies.
- Experience with GitLab, merge-request workflows, source control, GitLab CI/CD, runners, pipeline artifacts, and automated quality gates.
- Solid understanding of distributed systems, event-driven architecture, microservices, Linux, containers, CI/CD, and automated deployment pipelines.
- Strong debugging, analytical, communication, collaboration, and independent-working skills.
- Bachelor’s or master’s degree in Computer Science, Software Engineering, Computer Engineering, or a related field, or equivalent practical experience.
- Must be able to work in Canada and obtain clearance under the Canadian Controlled Goods program and Reliability.
Benefits
- Work location is Canada-based, and the successful candidate must be able to work in Canada.
- The role offers senior individual-contributor scope with no people-management responsibility.
