|Schafer Corporation is seeking a Precision Engineer for Micro-Scale Manufacturing to join its laboratory in Livermore, California. The ideal candidate will have experience with ultra-precision machining and 5 axis milling techniques. Candidates from disciplines other than mechanical engineering with experience in ultra-precision machining techniques and characterization will also be considered. Responsibilities will include component design, machine programming, fabrication, assembly, and precision metrology of manufactured components.
The successful candidate will function as part of a team responsible for research, development, and fabrication of targets with very high dimensional tolerances. These targets are used by experimenters at DOE National Laboratories and other institutions with large high-power laser facilities. They are complex assemblies on the scale of a centimeter but with sub-micron tolerances. The target components are composed of various metals, polymers, polymer films, aerogels, metal coatings and precision manufactured components. These components are precisely assembled and characterized via conventional microscopy, interferometry, and optical coordinate metrology.
Responsibilities will include planning, directing, and executing an ongoing research and development project in the areas of micro-to-nano scale fabrication of 3-dimensional polymer structures by 2-photon polymerization (2PP), 3-D micro stereo lithography (3DMSL), and combinations of these techniques. Schafer collaborates with scientists and engineers from industry and academia on this cutting-edge research, and the successful candidate will be expected to maintain and expand these collaborations. This is a hands-on senior scientific position. The successful candidate will be expected to directly contribute to some or all of the following: expanding and controlling the material compositions and structures available by 2PP and 3DMSL; investigating fabrication of low density and metallic structures; increasing 2PP writing speeds through, for example, optical engineering, advanced motion control, and/or photo polymerizable resin and initiator development; and developing 2PP process models that can guide the development efforts.
