EXPERIENCE
Owner, Design Engineer, Manufacture Engineer, Marketing, Sales, Phantom
Splitboard Bindings, Evergreen CO July 2011 – Current
- Work with professional athletes and professional splitboard guides to design, prototype
and produce a novel splitboard binding.
- Responsible for writing and following through the patent process. Currently in the
application process with a publication number of: US 20140091557 A1
- Create manufacturing drawings and work with manufacturing companies to produce
bindings.
- Manage all aspects of running a small business from engineering to sales.
Mechanical/Thermal Engineer, Paragon SDC, Lakewood CO Jan 2007 – Current
- Responsible for Orion Thermal Analysis team’s Day of Launch support for the first test
flight (EFT1) and various testing in preparation for the first test flight.
- Supported the final build and assembly of the EFT1 crew module at Kennedy Space
Center, specifically supported the build of the thermal control hardware for the
propulsion subsystem.
- Primary responsibility to perform thermal analysis under Lockheed Martin’s direction
for the NASA Orion human space flight program. Use of Thermal Desktop ® as primary
tool to perform spacecraft system and component level thermal analysis. Documented
work through detailed technical memos, and presented results at technical interchange
John Keffler
meetings. Major items analyzed: Active Thermal Control System, Service Module
radiators, vehicle performance under failure conditions and vehicle ascent performance.
- Responsible for coordinating Paragon’s contract with Lockheed Martin to provide
thermal analysis under Lockheed Martin’s direction. Responsibilities included managing
Paragon thermal analysis team, writing contractual bases of estimates and negotiating
support issues with Lockheed Martin’s thermal lead.
Mechanical Engineer, Peerless Pump, Lubbock TX Oct 2005 – April 2007
- Established and managed the test facility in Lubbock TX. Responsible for selecting and
designing test equipment for the Lubbock facility. Project manager and design engineer
for the modernization of the test facility (half million dollar budget) at the company’s
headquarters in Indianapolis, IN.
- Interfaced to the company’s SQL database with LabVIEW and Excel in order to
automate testing, reduce test time, improve test accuracy and reduce retests.
- Provided hydraulic engineering support for vertical and horizontal pumps upon
reviewing test results. Determined appropriate action for correcting pump performance.
