(Only US Citizens & US Permanent Residents will be considered for this position.) (Hybrid role Tuesday through Thursday in our Plano office.)

What You Will Do

Forescout is seeking a highly motivated SDET to join our U.S. On-Prem Delivery team. You will design and execute automated test strategies. Your work will directly impact customers running some of the world's most critical networks. The ideal candidate brings excellent automation testing skills, attention to detail, and the initiative to fill gaps to ensure product quality in an on-prem environment.

• Test Planning & Design Ownership: Analyze product requirements and develop comprehensive test strategies. Create well-structured test plans and test cases to validate new features and system behavior.

• Automated Testing Development: Develop and maintain automated test scripts and frameworks for both front-end and back-end components of our cloud-based applications. This includes scaling UI and API test suites to increase regression coverage across multiple deployments.

• Manual & Exploratory Testing: Execute both manual and automated tests to verify functionality across various areas of the product. Validate security and compliance controls (RBAC, patching, logging) through automated test suites. Generate test execution reports as evidence for audits

• Defect Tracking & Resolution: Identify, document and track software defects using our bug tracking system (e.g. Jira). Work closely with developers to reproduce issues, troubleshoot root causes, and verify fixes ensuring timely resolution of all high-priority bugs.

• Regression & Performance Testing: Improve and scale our test frameworks for regression and performance testing. Continuously enhance internal testing tools (e.g. expanding automated regression suites) and contribute to performance testing efforts to ensure the application meets scalability and response time goals

• Quality Best Practices: Ensure that QA best practices and processes are followed at all stages. Proactively review requirements and design documents for testability and provide feedback to improve product quality and user experience.

• CI/CD Integration: Integrate automated tests into the continuous integration/continuous delivery (CI/CD) pipelines. Monitor test results from CI runs (e.g. in Jenkins/GitHub Actions) and work with the team to address failures quickly.
