• Bachelor's degree in computer science, engineering, or a related field, or equivalent practical experience.
• 3–4 years of experience in software development, test automation, or quality engineering.
• Proficiency in Python or a comparable object-oriented language such as Java, C#, Ruby, or JavaScript/TypeScript.
• Experience with Gherkin/BDD frameworks.
• Experience with mobile UI automation such as Appium, Espresso, or XCUITest.
• Comfort with REST API testing, including OAuth-based authentication flows, building and debugging HTTP request wrappers, and interpreting API error responses.
• Experience 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 and ability to collaborate across technical and nontechnical teams.
• Ability to work on-site a minimum of three days per week.

Nice To Haves

• Experience testing cloud-based applications or services in AWS, Azure, or Google Cloud.
• Working knowledge of Docker and dev containers for consistent local test environments.
• Experience testing Android applications using UiAutomator2, adb, or similar tools.
• Familiarity with test reporting tools such as Allure or ReportPortal.
• Experience with performance and load-testing tools such as k6, JMeter, or Gatling.
• Knowledge of accessibility, security, contract, or resilience testing.
• Experience improving test architecture, reducing flaky automation, or modernizing legacy test frameworks.
• Familiarity with observability platforms and production-quality monitoring.
• Practical experience using AI coding tools, with the judgment to verify and adapt AI-generated code.
• Experience mentoring engineers or leading quality initiatives across multiple teams.
• Experience in a regulated or compliance-driven domain.

Responsibilities

• Design, develop, and maintain automated test cases and suites using established frameworks and patterns.
• Create test strategies and plans for functional, integration, regression, end-to-end, performance, and reliability testing.
• Integrate automated tests into CI/CD pipelines and improve the speed, stability, and usefulness of test feedback.
• 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, including defect trends, test coverage, escaped defects, and automation reliability.
• Reduce flaky tests and improve automation suite maintainability and execution efficiency.
• Participate in code reviews and promote engineering practices that improve testability and software quality.
• Conduct manual and exploratory testing for ELD compliance solutions, including hardware-in-the-loop setups and in-cabin vehicle testing.
