Next Generation Display and Control Unit (xDCU) sub-system Design Lead for the xEMU Next Generation Spacesuit for NASA missions to space, the Moon and eventually Mars. The xEMU is essentially a spacecraft the astronaut enters to perform tasks in the realm of space outside the ISS space station or on the moon. The xDCU is a small electronic control box mounted in the chest area of the suit. The astronaut interfaces with the xDCU to control and/or monitor different subsystems on the suit. The Design Lead is the main point of contact for all design and development activities on the xDCU. This includes working with project team, stress analyst, drafters, designers and the NASA sub-system lead to provide timely, cost-effective design solutions that meet program requirements.• Responsible for DCU sub-system CAD model, drawings and overall quality, creativity and delivery of the DCU per NASA requirements• Coordinates with xEMU Design Integration Lead to ensure all work is consistent across program• Directs DCU team to accomplish the design plan as required by NASA• Provides bi-weekly update via Power Point presentation in live meeting format with NASA customer and cross functional team• Mentors younger engineers and new hires • Reviews and approves all drawings, tolerance analyses and CAD models prior to submitting to NASA• Serves as main point of contact for all development and design activities on the sub-system• Maintains Bill of Materials, meeting minutes, and all relevant documentation for project

Operated as lead mechanical engineer for the ZXPLR node cradle to grave design and development. The ZXPLR is 3500m rated subsea autonomous electronic seismic sensor package ROV deployed for offshore seismic surveys. Primary focus on delivering production ready CAD models, assemblies and drawings for the entire ZXPLR program in CREO/Windchill. Provided BOMs, assembly drawings/procedures, and part quotations to manufacturing and purchasing to implement NPI builds. Primary mechanical engineer for any production start up issues. Beyond new product development duties, provided mechanical hardware design support for operations, suppliers and manufacturing. Other projects included lithium ion charger/data recorders, various electronic packagesusing NEMA 4x boxes, external production tooling and internal manufacturing fixtures (3d printed and machined) for PCA wave soldering and battery assembly. • Lead design engineer for the ZXPLR node successful product launch in 2017, with node generating more than 50% of deep- water acquisition revenue for 2019-2020. 8000+ nodes have been built to date.• Patent pending component design for a field serviceable sub-sea 6,000-psi-rated connector system, U.S. Patent application 16/003226. Managed design from concept to production. Organized all design validation pressure testing and qualified new supply chain for production (molding and machinists).• Submitted pending patent for design of modular automated node charging system robot, fully automated charging system to reduce HSE personnel exposure offshore. U.S. Patent Application 16/597555.• Managed implementation of new material supply chain for ZXPLR housings. Sourced new suppliers for raw material and heat-treating. Created specifications and QC controls to ensure final material met design specifications. Coordinated with testing labs to validate material properties prior to production start.
