FCA(contract) October 2018 to February 2019

Driveline Specialist

Work in the driveline CoE developing driveline system processes for the design and development of the driveline system.

Driveline system expert for driveline systems

Assisted in problem resolution in the AWD systems FCA was having

Allegiant International May 2018 to October 2018

Technical Advisor

Advisor as needed for various projects. Assisted suppliers that are in trouble delivering product due to technical of material flow issues

GKN Driveline Newton August 2017 to May 2018

Product specialist

Work with assembly test machine suppliers to improve many test issues resulting in part failures and machine down time.

Develop methods to reclaim units that failed the assembly process.

Work on day to day build, design or quality issues that arise.

Lead the team to develop a recovery process for assemblies that failed original assembly.

This resulted in over $15 Million recover of parts that would have been scrapped.

Worked on reduce issues resulting in rework on the line or scrapping of assemblies

Used Red-X processes to determine issues on the production line.

Worked to get Red-X as a tool in the plant

Engineering Manager and driveline technical specialist September 2015 to April 2017

Driveline System Technical Integration Engineering and Manager for Driveline Hardware In the Loop (HIL) Lab.

Leading the activity to move the driveline team to more of a systems approach vs components approach.

Led the development of doing HIL testing of the driveline. This lab used a combination of a number of simulation software such as CARMAKER, Simulink, AVL Puma, dSpace, Matlab.

Developed the first cell doing this type of testing in the industry, this has brought the testing much earlier in the product cycle off the vehicle and has improved the capability of testing in the lab.

Was one of the GM active clutch systems technical leads for all types of active clutch systems

Worked with the software engineers from the suppliers to get the required and desired performance of the driveline systems

Used Red-X and DFSS internal to GM and with suppliers to resolve issues

Was involved in the completion of the Sub-system technical specifications for driveline systems and components.

Worked with our service team to develop and implement a new service tool to diagnosis NVH issues in the driveline. This tool can also be used on other vehicle systems like tires

Engineering Manager and Driveline Technical Specialist January 2014 to September 2015

Led the design, construction, staffing and process for a new $42 Million driveline lab, this was done in 18 months from start of design to full commissioning of the lab, this included dyno’s, structural testing, a full gear lab, materials lab, prototype build area and a full vehicle garage area.

Managed a group of driveline development and test engineers developing several new driveline test procedures and developing outside testing houses to execute driveline testing for General Motors.

Was technical advisor to the driveline calibrators, and driveline development engineers

Powertrain Hardware Development Manager January 2001 to January 2014

Manager for Driveline, Induction, Exhaust and Shifter Control development team.

Manager of new team that was to develop to do testing and development of the driveline, induction, exhaust and shifter controls at the sub-system level off the vehicle.

Developed the roles and responsibilities for the team.

Worked with vehicle integration, design and validation teams to determine where this process fit into the overall vehicle development process.

During my time we developed a number of new labs for induction, exhaust, and transmission shift controls, these labs are now the standard for GM suppliers.

Team developed several new test procedures for these new labs that are used at GM and at our suppliers.

Worked with our validation teams to develop DVP&R plans and templates for both the work at GM and our suppliers

Worked on a new requirement, design guidelines and test procedure for air intake temperature a major performance issue with our vehicles

Ran a DFSS project to resolve a major testing issues with noise testing

Led the Development, design and installation of the new driveline HIL dyno, this is the most advanced dyno for driveline in the world.

Lead the implementation of the calibration and development tools

Implemented a number of new NVH tools for the team

Developed a training program for all development engineers

Was a technical specialist in the induction, exhaust and driveline area

Powertrain Integration Engineer September 1995-January 2001

L6 engine Powertrain System Integration Engineer for 2000 model year Trailblazer and Envoy vehicle programs.

Led packaging, wrote engine specification and powertrain specification, did performance calculations and transmission requirement development build process

Lead the development of the engine DFMEA

Worked with manufacturing to complete the PFMEA and build process

Headed the packaging study of the V8 into this platform.

Responsible for the managing the vehicle fuel economy performance

Design Release Engineer October 1992 – September 1995

Current product support for small truck responsible for powertrain integration, axles, mechanical controls.
