Your role and your team: 

The Laboratory Testing department is responsible for component, system, and aircraft level tests. Our teams develop rigs and run tests that facilitate research, development, and certification in the technology areas propulsion, batteries, structures, and electronics.

In this role, you will work in the Propulsion Testing team, which is responsible for preparing and conducting tests on the propulsion system. We collaborate closely with the design team to ensure the most effective testing approach for our product.

As a Senior Test Engineer, you will have end-to-end responsibility of a test from its initial request until delivery of the test data, always keeping the goal of qualification and certification of our aircraft in mind. As recognized expert in your field, you will support and advise our design office with the definition and evaluation of test campaigns, as well as guide your team members on their test projects. You will support the test management and use your experience to provide guidance to colleagues to establish and comply to processes, methods, and best practices for propulsion testing and propulsion system certification (SC-VTOL, SC-EHPS). For test campaigns at external laboratories, you will act as the technical focal point and coordinator as well as support the execution of the test at the supplier site.

For complex test setups which require new facilities, you will be the rig development engineer, including coordination of design and manufacturing suppliers. Moreover, you will guide and implement the development and maintenance of our internal test facility when needed.
