Professional Objective:
Obtain a position that will provide new and challenging work and the opportunity to contribute in a team environment through continued development of professional skills and application of current skill sets.
Professional Qualifications:
R&D Hardware Engineer
Major responsibilities included delivering test bed / product power electronics, architecture of system voltage regulators and development and characterization of analog circuits in both high volume consumer electronics and low volume commercial electronics markets. Providing engineering support for reliability and qualification testing of new products and cost reduction efforts of existing products using new system components or modules. Serving as a member of the Analog and Power Asset Team, delivering power solutions across many diverse business units that do business in a global geography with a wide range of market segments. Performed an integral role leading power supply new technology research, including development of technology for emerging high volume markets.
Demonstrated Capabilities
· Developed Asset delivery schedules based on multiple product build and release schedules, safety and regulatory submittal schedules and contract manufacturing and shipping lead times for both assets and products.
· Designed and executed functional electrical test plan for power assets and product asset combinations, integrated these plans with reliability test plans and supported qualification testing and defect tracking. This included the use of custom board designs utilizing FPGAs to implement tests when final products were not available and schedules for other teams required results.
· Participated in design and layout reviews dealing with issues such as Printed Circuit Board (PCB) stack ups, Electromagnetic Compatibility, Noise and Thermodynamics relating to circuit operation as well as PCB manufacturing. Also participated in design reviews for mechanical layouts, design and physical placements.
· Supported PCB manufacturing and product prototype early manufacturing builds at contract manufactures.
· Contributed technical inputs influencing future low power energy management strategies, product architectures and implementation plans for green product design initiatives.
· Implemented test methodology for Power & Analog assets using MATLAB to process measurement data into meaningful results that optimize design of each asset as well as the integration of the right assets to the right products.
· Investigated new technologies, particularly technologies that solved quality problems and reduced failure rates in geographic areas of poor electrical power infrastructure and growing economies, growing consumer markets and large overall market growth opportunities for consumer products.
· Collaborated with Safety, Environmental Stewardship, Procurement, Product Regulatory and Product Design Teams across multiple site geographies to implement process improvements that cut the development time for Power Assets in half.
· Traveled Globally to Asia and Europe to conduct technology and design reviews with remote teams, suppliers and contract manufactures / designers.
· Assisted Procurement in evaluation of vendor manufacturing lines and outsourced test facility capability for Power Assets.
