Mechanical Engineer
Summary
Mechanical design and development,
from product specification and concept through manufacturing in FDA regulated
environments. Interdisciplinary and interdepartmental communication skills.
Vendor evaluation and high-tech component sourcing. Analysis of persisting
or unprecedented problems. Technology/feasibility studies. AutoCAD.
"Product development
today frequently presents problems for which there exist no prior definitions.
In these situations, the responsible engineer must become expert where
there are no experts. New technologies not only might, but usually do,
cross discipline boundaries. Coping with lack of definitions, and working
outside of my core discipline is something I often do."
