## Description

Radia is seeking an experienced flight control systems engineer to lead the development, integration, and certification of a fly by wire primary flight control system. This will include both the internal technical system development as well as an international team of suppliers for the flight control system. This engineer will oversee development of the entire flight control system including flight deck controls, computing and actuation subsystems for the world's largest airplane.

The flight controls engineer will primarily lead the architecture layout, requirements definition, sizing, design, ICDs, development, production, integration, testing and certification of a fly-by-wire flight control system for a part 25 aircraft development. This includes providing supplier coordination and technical oversight and flight control system integration across various functions within Radia and across multiple partners and suppliers. Radia is a collaborative and creative environment, an ideal candidate would be able to develop and certify a robust system while also thinking creatively about how to minimize the development effort, technical risk and driving simplicity into the design.

Responsibilities

 * Help build and lead the Radia flight control systems team
 * Establish system architecture and system performance capabilities
 * Define and maintain system functions and requirements
 * Select/define major components including electronics, pilot inceptors, actuators and sensors
 * Interface and lead across program customers, suppliers, and other engineering stakeholders
 * Oversee airplane integration of flight controls, supplier testing, integration lab testing and airplane testing, including developing testing plans, lab requirements, instrumentation requirements and test procedures
