Develop and run AI&T test procedures, maintain test logs and reports, use GSE and test equipment, troubleshoot systems, collaborate with engineers and customers, and support launch operations.

Design, build, and maintain automated test scripts, frameworks, and CI/CD-integrated test environments to validate system functionality, performance, and reliability. Create test plans, run regression and load tests, analyze results, report and track defects, and collaborate with engineers and managers. Configure test environments, research testing tools, and produce technical documentation and presentations for technical and non-technical stakeholders.

Lead comprehensive testing for embedded firmware and software across pre-silicon and post-silicon development. Design black-box, white-box, stress, integration, regression, and system test strategies; develop automated test frameworks and hardware-in-the-loop infrastructure; debug and triage defects with cross-functional hardware, firmware, software, and systems teams; analyze and present coverage, risks, and test results. The role also requires technical leadership, requirements-based test-case development, and system reliability validation.

Leads system-level integration and test engineering for the Sentinel strategic deterrent program. Establishes technical baselines, ensures sound engineering processes and quality compliance, supports technical and program review boards, resolves cross-team design issues, advances integration and verification strategies, engages customers and partners, and mentors technical leaders across integrated product teams.

Lead the build-out and management of high-voltage battery test capabilities: define test strategy, establish lab infrastructure and safety/processes, run pack- and cell-level performance, abuse, and destructive tests, oversee failure analysis and data systems, and hire/develop a test engineering team to provide rapid feedback to design groups.
