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. SUMMARYThis is the position of Opto-Mechanical Design Engineer, Central Engineering Department (CE), Smithsonian Astrophysical Observatory (SAO). The purpose of the position is to support the Observatory’s scientific investigations by providing mechanical, structural, and potentially project engineering expertise to the development of advanced ground-based instrumentation for astronomical/astrophysical data collection and related telescope systems. The incumbent will collaborate with scientists to identify pioneering technologies to be applied to the development of innovative instruments that support the advance of Observatory scientific research objectives and will ensure the translation of these concepts into functional hardware. The incumbent will be required to support multiple complex projects simultaneously. MAJOR DUTIES Project Leadership: Leads mechanical subsystem development with significant complexity. Oversees design, construction, and maintenance of complex opto-mechanical systems. Incumbent provides technical consultation, guidance, and task leadership. Advises senior leadership, program officials, and colleagues on engineering analysis, recommendations, and study conclusions (e.g., advising director on region-wide implementation plans for new or updated standards). Leads, plans, develops, and prepares procedures, policies, and/or protocols for mechanical engineering studies and special projects that require advanced engineering analysis that extends or modifies theories, concepts, and assumptions or resolves unique or novel problems, conditions, or issues. Plans and coordinates programs or projects which are innovative and original. Develops methods and procedures which become the established precedent. Engineering analysis may result in significant alteration of standard practices, processes, devices, equipment, and known techniques. Studies and projects include technical planning activities; data collection; modeling and data analyses; analyses of site location and/or conditions; risk estimation and analyses; and analyses of instrumentation data. Engineering analysis advances engineering methods, practices, and procedures; conclusions, recommendations and/or decisions are based on this high-level analysis. \nTechnical Consultation:\n Provide expert advice to senior colleagues, agency officials, and stakeholders.

Remains current with agency and national standards in the mechanical engineering industry (e.g., American Society of Mechanical Engineers (ASME). Provides technical reviews, peer reviews, and checking of designs, drawings, engineering analysis, technical documents, specifications, cost estimates, and contract correspondence, ensuring documents are accurate and quality assurance processes were followed. Reviews may be outside of the organization or designed by others. Signs documents for technical approval in accordance with project and department policies, directives, and standards; this includes signing as the engineer in responsible charge. Design & Analysis: Conduct advanced mechanical engineering design, calculations, and reviews. Develops engineering technical guidelines and standards, and/or project or study objectives. Advises technical teams, developing technical procedures and practices for the teams. Provides technical, mentorship, guidance, instruction, and advice to engineers and technicians and other internal and external stakeholders. Problem-Solving: Identify and resolve engineering design problems. Recommend innovative solutions for instruments, facilities, infrastructure, or energy systems. Documentation & Compliance: Prepare technical reports, specifications, and guidance documents. Ensure projects meet performance, safety, and sustainability requirements. Incumbent in collaboration with CfA scientific investigators, the incumbent conceives, designs, and constructs highly complex scientific instruments, their support structures, optical systems, associated mechanisms, and test equipment that are at or extend state-of-the-art. Assignments will include the complete instrument life cycle, from conceptual design through integration, test, commissioning, operations, maintenance, and repair. Provides expert technical consultation to CfA scientists and other engineering staff in instrument mechanical design, state-of-the-art mechanisms, materials and processes selection, fabrication, and assembly methods, and fixturing, particularly in the areas of motion control devices, high reliability mechanisms, and general robotics.
