Mcgregor, Texas, United States

Led a dynamic team of 5-8 engineers and specialists to support rocket development and product acceptance testing. Team was responsible for designing, building, maintaining, and upgrading multiple rocket test stands and the supporting infrastructure. Includes cryogenic propellant storage/distribution depots, vacuum chambers, hypergolic propellant storage, thrust and performance measurement, and more. Supporting >10 different test positions, and 2 major product lines (integrated Falcon vehicle and engine acceptance testing, and Dragon capsule engine acceptance testing).Lead role included recruiting for full time and intern positions, training new hires, managing project/work load internal to the team and externally with other team leads, serving as subject matter expert for team design reviews.Supported annual internal, and external AS9100, DCMA, and other customer audits (both surveillance and recertification).Individual contributor in the Test Equipment Engineer role for several smaller projects (working lead).
