Professional Objective:
Obtain a position that will provide stimulating 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 Experience & Qualifications:

R&D Electrical 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. As a member of the Analog ASIC and Power Supply Teams; delivered 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 Power Supply & Analog ASIC delivery schedules based on multiple product build and release schedules, safety and regulatory submittal schedules and contract manufacturing and shipping lead times.
·         Designed and executed functional electrical test plan for power supplies and product combinations, integrated these plans with reliability test plans and supported qualification testing and defect tracking.  This included the use of custom test board designs utilizing FPGAs to implement tests when final products were not available early in the design cycle.
·         Participated in design and layout reviews dealing with issues such as Printed Circuit Board (PCB) routing, Electromagnetic Compatibility, Noise and Thermodynamics relating to circuit operation as well as PCB manufacturing.  Also participated in design reviews for mechanical layouts and physical PCB placements.
·         Supported PCB manufacturing and product prototype 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 Supplies & Analog ASICs using MATLAB to process measurement data into meaningful results that optimized design and integration of correct designs into 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 HP geographies to implement process improvements that cut the development time for Power Supplies 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 Supplies.
