I work in the Product Integration & Validation organization in the Build Operations group. My main responsibilities are in overseeing the physical build of prototype units for test and retrofits. I work with Program Management and Design Engineering to collect up-to-date data on parts, build instructions and other technical information needed for a successful build. I use this information to establish a build schedule and work with mechanics to install prototype configurations on vehicles in our test fleet. This is often the first time that a new design is physically validated. I report out to the team any concerns regarding fit or function and work with both design engineers and mechanics to contain any concerns that impede build progress.
