Responsibilities

Develop, maintain, and execute detailed test plans, test cases, and test procedures for software-hardware integration, interface validation, sensor data handling, and autonomy module performance
Perform manual exploratory, functional, regression, and system-level testing in integration labs and hardware-in-the-loop (HWIL) environments
Design, implement, and maintain automated test frameworks and scripts (UI, API, integration, and performance) to accelerate verification within CI/CD and MLOps pipelines
Collaborate with software developers, systems engineers, and the Scrum Master to define acceptance criteria, automate regression suites, and shift quality left in every sprint
Conduct integration & verification (I&V) activities, including defect triage, root-cause analysis, and verification of MOSA compliance and interoperability requirements
Integrate automated tests into DevSecOps pipelines (static/dynamic analysis, container scanning, and model validation) to ensure secure, repeatable deployments
Support formal qualification testing, field demonstrations, and operational assessments for USSOCOM unmanned platforms
Document test artifacts in tools such as Jira, Confluence, and test management systems while maintaining traceability to program requirements
Identify process improvements, champion test automation best practices, and mentor junior testers on manual and automated techniques
Work in compliance with DoD, USSOCOM, and program security requirements while sustaining high Agile velocity in a high-tempo, sometimes classified development environment
