Trust Fund positions are unique to the Smithsonian. They are paid for from a variety of sources, including the Smithsonian endowment, revenue from our business activities, donations, grants and contracts. Trust employees are not part of the civil service, nor does trust fund employment lead to Federal status. The salary ranges for trust positions are generally the same as for federal positions and in many cases trust and federal employees work side by side. Trust employees have their own benefit program, which may include Health, Dental & Vision Insurance, Life Insurance, Transit/Commuter Benefits, Accidental Death and Dismemberment Insurance, Annual and Sick Leave, Family Friendly Leave, 403b Retirement Plan, Discounts for Smithsonian Memberships, Museum Stores and Restaurants, Credit Union, Flexible Spending Account (Health & Dependent Care). 

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, Smithsonian Astrophysical Observatory. The purpose of the position is to support the scientific investigations of the Observatory by providing opto-mechanical engineering expertise to the development of ground, balloon, airplane, or space-based astrophysical data collection instrumentation and associated support and test equipment. The incumbent may be required to support multiple projects simultaneously. 

1. Design: Provides design engineering support to the opto-mechanical aspects of astrophysical instrumentation and associated test and support equipment, from concept development through final design. This includes items such as optics (mirrors and lenses), optical mounting structures, alignment hardware (both instrument and support equipment), telescope structures, calibration systems and other items as needed. Is fluent in the use of CAD software for mechanical design. Prepares drawings of optical and mechanical parts and assemblies. Is responsible for specific design tasks under the direction of the project engineer, lead mechanical engineer and principal investigator.

 

2. Analysis and Error Budgeting: Under the direction of the project engineer and principal investigator, uses optical design and modeling software such as Zemax, Sigfit and FRED to conduct analyses of the performance of the optical system. These analyses include image quality, throughput, stray light, and mechanical interactions which impact optical system performance. Develops error budgets for performance aspects of the optical system, including image quality and throughput. Helps to performs optimization of the optical designs to balance cost, schedule and performance. 

 

3. Procurement and Fabrication: Supports, in conjunction with other program staff, the procurement and fabrication process for opto-mechanical items such as lenses, mirrors, mounts and electro-optical components. Conducts vendor surveys and prepares procurement specifications for selected components. Participates in vendor selection process. As directed, acts as the vendor point of contact for optical elements. As directed, oversees opto-mechanical fabrication at specified outside vendors to assure that fabricated parts are consistent with the design. Supports Product Assurance in performing incoming and in-process inspection and in assessing compliance to requirements. 

 

4. Assembly, Integration and Test: Supports assembly, integration and testing of the optical elements of instrumentation projects. Conducts testing of optics and optical assemblies using CE interferometers. Under direction of the project engineer, performs assembly and end-to-end optical alignment of optical systems. Supports integration of instrumentation in the field. 

 

5. Leadership: Serves as opto-mechanical task lead as assigned. Prepares opto-mechanical sections of project reports. As assigned, presents opto-mechanical sections of program reviews such as the preliminary and final design reviews. 

 

6. Documentation: Documents work performed through regular technical reports and memoranda. Participates with other engineering and scientific staff in evaluating aspects of new instrument concepts, writing proposals, and performing trade-off analyses in support of future instrument development. 

7. Travel: Travels as required in support of above duties.

 

8. Other: Performs other duties related to the position as assigned by supervisor and/or Central Engineering manager.

Basic Requirements:
A) Degree: professional engineering. To be acceptable, the curriculum must:
