Senior Test Engineer - Propulsion | Motors R&D

At BETA Technologies, we apply our intellectual curiosity, passion for aviation, and commitment to sustainability toward a shared mission of revolutionizing electric aviation. Regardless of the position one holds, each team member brings their talent and desire to positively impact the environment and lives of others in a refreshing, vibrant, and inclusive culture. The propulsion test engineer serves as a technical leader responsible for the development and execution of comprehensive test programs for aircraft electric motors, inverters, and their components. This role owns the end-to-end test strategy—from test stand architecture and instrumentation design through data analysis and certification documentation. The test engineer will partner with multiple teams to define design validation requirements, develop test methodologies, and drive continuous improvement of test capabilities. This individual will mentor junior engineers and serve as a subject matter expert on high-voltage propulsion system testing. Engineers with aviation background may also lead propulsion-focused flight test campaigns. This is an exciting opportunity to shape the future of electric aviation testing in a fast-paced, dynamic environment. How you will contribute to revolutionizing electric aviation: (Essential Duties and Responsibilities) Lead the design, development, and validation of high-voltage electrical test systems for inverters, motor controllers, and electric propulsion units Own test program planning and execution for component, system, and aircraft-level validation under dynamic and environmental conditions Define and execute EMI/EMC test campaigns; develop mitigation strategies for conducted and radiated emissions in high-power switching environments Architect test stand configurations, select instrumentation, and develop automated test sequences Partner with power electronics and motor design engineers to establish electrical acceptance criteria and validation coverage requirements Drive root cause analysis of electrical anomalies, power quality issues, and system failures; present findings to cross-functional stakeholders Author test reports and certification documentation to support FAA/regulatory compliance Establish high-voltage safety protocols and mentor junior engineers on safe work practices around energized systems
