2022 – 2023
Technical Program and Project Manager
Led team to resolve a PCBA test article bottleneck for automated testing leading into the satellite production ramp.
Refined a new dashboard style for top leadership to resolve broken dependencies across subsystems.
2017– 2022
Senior Mechanical Engineer
Procured and managed the high-temp 3D printer for faster iterations on internal prototypes and PEI test tooling.
3D printed, smoothed, and painted a cosmetic fit check unit with D38999 connectors to check cable routing.
Designed injection molded chassis from ID surface model, and led fixing the cracking issue from the mold slider.
Led the transition to ASME Y14.41 annotated models for more complex CNC geometry and CMM inspection.
Cost savings of over $200/unit by simplifying parts from molded to machined & from custom to COTS connectors.
2015– 2017
Mechanical Engineer & Certification Specialist
Mechanical design ownership of airplane engine seals, bearings, and flight critical consumable components.
Research of failure modes and effects through systems manuals and collaboration with field techs.
Technical writing of 10 certification reports approved by the FAA with statistical analysis of tolerance and fit.
Rebuilt the 3D printer and product photography areas for better quality and ergonomics for process improvement.
