* We are seeking a  
** Senior Test Automation Engineer
** to design, build, and maintain automated test solutions for both REST APIs and web-based user interfaces. This role requires hands-on expertise in Linux command-line tools, Python automation, containerized test execution using Docker/Podman, and CI/CD integration with Jenkins and Git Lab. The successful candidate will also help evolve our in-house automation framework by planning and executing the migration from legacy Robot Framework implementations to newer automation platforms.

** KEY RESPONSIBILITIES*
* + Develop, maintain, and enhance automated test suites for back-end REST APIs and web-based user interfaces.

+ Build and maintain a scalable, reliable test automation harness (framework) including execution, reporting, data setup/teardown, and CI/CD integration.

+ Implement and expand Python-based test automation using Pytest, including fixtures, test data strategies, and robust assertions/validation.

+ Create and maintain Docker/Podman container images used to run automation consistently across developer environments and CI pipelines.

+ Integrate automated test execution into Jenkins and Git Lab CI/CD pipelines, ensuring repeatable runs, clear reporting, and actionable results.

+ Use Linx command-line tools and Bash shell scripting to locate, parse, transform, and report on large volumes of logs, test output, and system data.

+ Support and extend UI automation using Robot Framework and the Python Selenium library, including test stability improvements and best practices.

+ Collaborate with stakeholders to plan, estimate, and break down work for migrating the current in-house test harness from legacy Robot Framework to a modern alternative (e.g., Robot Framework AIO or Microsoft Playwright).

+ Write and maintain SQL queries (using SQL Developer or similar tooling) and integrate database validation steps into automated tests were appropriate.

+ Troubleshoot CI failures and test irregularity/volatility, improve test reliability, and contribute to continuous improvement of the overall QA automation approach.

+ Strong experience with Linux and Bash shell scripting, with demonstrated ability to work effectively from the command-line and process/report on large data sets (logs, test artifacts, results).

+ Advanced experience building test automation in Python, including Pytest-based frameworks and best practices for maintainable automated testing.

+ Strong hands-on experience with Docker (or Podman) including building, versioning, and maintaining images used in automation and CI/CD workflows.

+ Working knowledge of Jenkins and Git Lab pipelines, including running containerized workloads and managing automated test stages.

+

Experience with REST API testing, including validation of responses, authentication flows, and negative/error-path testing.

+ Familiarity with Robot Framework UI automation using Selenium library (Python).

+ Solid understanding of how to architect a test automation harness/framework for UI and/or API testing (test structure , configuration, reporting, environment management).

+ Familiarity with SQL and tools such as SQL Developer, including writing queries and using them within automated validation steps.
