• 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.

REQUIRED QUALIFICATIONS

• 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.

• Security Clearance Requirement: Active TS/SCI with polygraph

PREFERRED QUALIFICATIONS

• Experience planning and executing test automation framework migrations (e.g., Robot Framework to Microsoft Playwright or Robot Framework AIO).

• Experience improving CI performance, parallelization, and test execution efficiency in containerized environments.
