• We are looking for a Senior SDET / QA Automation Engineer to join our Libcare Live Patching Team.
• The Libcare team is a division of TuxCare that specializes in applying live patches to running processes without rebooting the operating system. To do this, we build "live" patches from the source code and then apply them to running processes using our patch engine. All of this must be thoroughly tested, from the patch creation step to its successful application and the correct behavior of the process that received the patch.
• Work is fully remote, with flexible hours, where you can plan your day and work from anywhere in the world.
• More details about the project can be found on the product website TuxCare.com - https://docs.tuxcare.com/live-patching-services/#libcare, and about the company - on Cloudlinux.com - https://cloudlinux.com/.
• As our SDET / QA Automation Engineer, you will do:
• 1) Test Environment Provisioning & Management
• Spin up and configure test stands to verify live-patching in various scenarios
• Analyze our users’ most popular products and systems (OS, containers, middleware, cloud platforms) to faithfully reproduce real customer cases
• Configure the software stack (libraries, framework versions, databases, etc.) and simulate load (traffic, user actions) as close to production as possible
• 2) Test Automation
• Design and evolve the test framework for existing test categories: unit, functional, regression, performance
• Integrate and maintain automated tests within CI/CD pipelines (Gerrit/GitLab, Jenkins, AWS, Nebula)
• Write clear, reliable, and scalable tests in Python
• 3) Pipeline Support & Optimization
• Monitor and troubleshoot pipeline failures: identify bottlenecks, eliminate flaky tests, and reduce execution time
• Set up reporting (Allure), notifications (Slack, email), and metrics dashboards (Jenkins Blue Ocean)
• 4) Process Analysis & Improvement
• Configure, collect, and analyze metrics on test coverage, execution time, and stability
• Propose and implement enhancements such as parallelization, test-impact analysis, etc.
• 90-Day Adaptation Period Tasks:
• Re-architect the Test Environment: Migrate the existing Bash-based test environment to a unified Python framework for unit, functional, and integration testing. Extract and modularize common utilities so that developers can easily write and plug in their own tests.
• Extend Test Coverage & Profiling: Integrate a test coverage tool and a profiling harness to measure performance and identify poorly tested sections of code
• Reproduce Customer Scenarios: Provision and configure environments that mirror key client setups and usage patterns. Execute live-patching and unpatching flows under real-world conditions.
• Deep Dive into the Patcher Engine: Figure out our patcher’s architecture to understand the most critical and potentially problematic zone
