• Design, develop, and maintain automated test cases for embedded HMI and desktop applications.
• Enhance and support an in-house Python‑based test automation framework.
• Develop scalable and reusable automation solutions to improve test coverage and efficiency.
• Create automated regression, functional, integration, and system‑level test suites.

• Automate graphical user interface (GUI) testing for embedded HMI devices and desktop applications.
• Validate application functionality, usability, and performance through automated testing.
• Collaborate with development teams to ensure high‑quality software releases.

• Build, maintain, and optimize CI/CD pipelines using Git Lab CI.
• Integrate automated testing into continuous integration and deployment workflows.
• Monitor, troubleshoot, and resolve pipeline failures and automation issues independently.
• Drive continuous improvement of testing and deployment processes.

• Manage virtual machine environments used for testing and validation.
• Create and maintain VM templates, snapshots, clones, and network configurations.
• Automate environment provisioning and management using APIs and command‑line tools.
• Ensure test environments are reliable, scalable, and easily reproducible.

• Investigate and resolve test failures, infrastructure issues, and pipeline disruptions.
• Analyze root causes and implement corrective actions to improve stability and reliability.
• Work closely with software developers and system engineers to maintain product quality.

• Strong programming expertise in Python.
• Proven experience developing and maintaining automated test frameworks.
• Experience automating GUI tests for:
  • Embedded HMI Applications
  • Desktop Applications
• Hands‑on experience with virtualization technologies, including:

  • Snapshots
  • Virtual Networking
  • API/CLI‑Based Automation
• Strong understanding of software testing methodologies and automation best practices.

• Solid experience with Dev Ops practices and automation workflows.
• Hands‑on expertise with Git Lab CI/CD pipeline development and maintenance.
• Experience troubleshooting and optimizing build, test, and deployment pipelines.

• Ability to independently diagnose and resolve automation, infrastructure, and pipeline issues.
• Strong organizational and analytical skills.
• Self‑motivated with the ability to manage priorities and deliver results with minimal supervision.

• Experience testing embedded systems or automotive HMI applications.
• Familiarity with Linux‑based development and testing environments.
• Experience with automated environment provisioning and infrastructure scripting.
• Exposure to hardware‑in‑the‑loop (HIL) or embedded device testing environments.
• Knowledge of software quality engineering and continuous testing practices.
