OVERVIEW

INTRODUCTION

The Smithsonian Astrophysical Observatory (SAO) is at the forefront, internationally, of the scientific exploration of the universe. SAO combines its resources with those of the Harvard College Observatory to form the Harvard-Smithsonian Center for Astrophysics (CfA). The CfA is the best-known astrophysics center in the world. Its programs range from ground-based astronomy and astrophysics research to space-based research, the engineering and development of major scientific instrumentation for space launch and use in large ground-based facilities, and research designed to improve science education. The research objectives of SAO are carried out primarily with the support of Government and Smithsonian Institution funds, with additional philanthropic support.  Government funds are in the form of Federal appropriations or contracts and grants from other agencies. In contrast, Institution funds are available to SAO through grants from the Institution's Restricted Funds, Special Purpose Funds, Bureau Activities, Business Activities, and non-Federal contracts and grants.

SUMMARY

This is the position of Opto Mechanical Engineer, Central Engineering Department (CE), Smithsonian Astrophysical Observatory (SAO). The purpose of the position is to support the Observatory’s scientific investigations by providing senior-level manufacturing engineering leadership to the engineering and scientific staff engaged in the development of complex ground-based optical instruments. The incumbent will mainly support projects such as Viaspec and instruments for the Giant Magellan Telescope; however, this position will also support air—and space-based projects as needed.
