Engineering Technical (Mechanical)

Summary

The Sub-millimeter Array (SMA) is a joint project of the Smithsonian Astrophysical Observatory (SAO). The observatory consists of a control building and hangar, eight relocatable antennas and associated instrumentation on the summit of Maunakea. The SMA is a radio interferometer array that conducts astronomical observations at millimeter and sub-millimeter wavelengths from 180 GHz to 420 GHz.

Duties

• •Conduct field inspections, measurements, and data collection for mechanical systems such as HVAC, pumps, piping, boilers, chillers, compressors, and fluid distribution systems.
• •Perform calculations related to flow, pressure, heat transfer, load, and system performance using established formulas and engineering references.
• •Read existing designs to complete packages, installation checklists, machine parts lists, and specifications of instrumentation equipment.
• •Assemble modified or new mechanical components for equipment and industrial and scientific machinery.
• •Conduct limited troubleshooting and diagnostics on mechanical equipment, identifying routine issues and recommending corrective actions.
• •Manage SMA's day to day operations of the fleet center; overseeing a diverse fleet including four wheel drive vehicles.
• •Provide technical assistance in developing maintenance and/or repair of precision mechanical assemblies at the observatory, including antennas, antenna transporter, and infrastructure.
• •Operate specialized bridge cranes, hoists and forklift trucks used in the assembly and maintenance of large antenna components.
• •Work with the antenna transporter, which is used to move the antennas.
