Responsibilities

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

Investigates, selects, justifies, and procures critical mechanical, servo-mechanical, and optical components used in astronomical/astrophysical instrumentation and its development. Prepares specifications for selected components that describe the technical approach and results and conclusions of engineering trades and analyses. Prepares procurement documentation that sets expectations and delivery criteria

Conducts detailed structural trades and analyses at the concept and detailed design levels to inform technical decisions. Supports the development of requirements and associated compliant systems designs

Actively participates in the assembly of complex instrumentation involving intricate structures, mechanisms, and optics. Provides technical leadership to overall instrument fabrication, assembly, and test activities, both in SAO laboratories and externally, including at vendor or partner facilities and/or telescope sites

Documents work in technical memoranda, reports, test plans, and procedures. Develops technical specifications to communicate needs internally as well as to suppliers and partners. May write technical papers, either singly or in collaboration with project scientists and other engineers, to publish innovative design techniques and present results at technical symposia

Serves as the project’s mechanical/structural representative to both internal and external stakeholders including senior management and staff at the CfA, collaborating or sponsoring organizations, and review teams. Makes both oral and written presentations to project scientists and technical representatives of contracting agencies and cooperating or affiliated organizations. Develops and presents detailed technical content at periodic status reviews, international conferences, and major gate reviews involving external partners. Serves on technical task forces, review teams, and committees

Travels both nationally and internationally as required to support project activities

Performs other related duties as assigned
