• Review product requirements and technical designs to identify risks, edge cases, and testability concerns early.
• Diagnose failures across application, test, infrastructure, and data layers, partnering with developers to resolve root causes.
• Monitor and report quality metrics such as defect trends, test coverage, escaped defects, and automation reliability.
• Reduce flaky tests and improve the maintainability and execution efficiency of the automation suite.
• Participate in code reviews and promote engineering practices that improve testability and software quality.
• Execute manual and exploratory testing for Electronic Logging Device (ELD) compliance solutions, including hardware-in-the-loop setups utilizing Android tablets, telematics devices/On-Board Computers (OBCs), and in-cabin vehicle testing.
• Must be able to work on-site a minimum of 3 days per week

• Experience with Gherkin/BDD frameworks.
• Experience with mobile UI automation (Appium, Espresso, XCUITest, or similar).
• Comfort with REST API testing — OAuth-based auth flows, building/debugging HTTP request wrappers, reading API error responses.
• Experience working with Git, CI/CD systems, and Agile software development practices.
• Ability to troubleshoot distributed systems using logs, metrics, traces, and debugging tools.
• Strong written and verbal communication skills, with the ability to collaborate across technical and nontechnical teams.
