• Validate end-to-end data pipelines across collection, analytics, storage, and reporting components.
• Conduct testing in Linux-based, distributed, and security-constrained lab, cloud, and operational environments.
• Document test results, defects, impacts, and recommended corrective actions.
• Collaborate closely with systems engineers, developers, and cybersecurity engineers to troubleshoot and resolve issues.
• Support Government test activities, including IV&V, operational testing, and test readiness events as required.

• Active DoD Secret clearance.
• 3+ years of experience in cybersecurity, network, or systems testing.

• Exposure to tools such as Wireshark, Zeek, Splunk, ACAS, Nessus, or similar.
• Experience testing in Linux-based or distributed environments.
• Ability to clearly document complex test scenarios and results.

• Experience with DevSecOps pipelines and automated regression testing.
