About the role

As a Senior Systems Test Engineer, you will contribute to the development of test equipment used to verify and validate complex aerospace systems and components against product requirements, following a standardized design and development process. In this role, you’ll focus heavily on electromechanical actuation system testing, ensuring test setups accurately simulate real-world conditions to validate performance and reliability. You will work closely with design engineers to support integration and system checkout activities using deployed test assets in lab environments.

This is a full-time onsite opportunity based out of El Segundo, CA.

Responsibilities

• Execute and support systems test activities in a high-tempo work environment, ensuring test objectives are met on schedule.
• Develop, implement, and maintain test procedures, setups, and documentation to support avionics systems and subsystems integration.
• Conduct system-level integration efforts in the Systems Integration Lab (SIL) environment, maintaining configuration control and traceability across all test assets.
• Collaborate with engineering teams to design, integrate, and troubleshoot harnesses and wiring for both SIL and aircraft applications.
• Prepare and maintain Bills of Materials (BOM) for test articles, lab hardware, and integration assets.
• Coordinate and support supplier activities related to environmental and EMI/EMC testing, including reviewing test plans, witnessing tests, and validating results.
• Work closely with cross-functional teams including GNC, Perception, Safety, Systems, Flight Test, and Software to ensure successful integration and testing of complex avionics systems.
• Identify and document test anomalies, perform root cause analysis, and support corrective actions to resolve integration issues.
• Contribute to process improvements in test methodologies, equipment usage, and integration workflows.

Requirements
