The Associate Fluid Systems Mechanical Technician is responsible for performing the maintenance, operation and commissioning of various fluid systems including cryogenics, and cooling water. This position will primarily support the National Spherical Torus eXperiment Upgrade (NSTX-U) cryogenic plant, however support of other experiments and fluid/mechanical systems is expected.

A U.S. Department of Energy National Laboratory managed by Princeton University, the Princeton Plasma Physics Laboratory (PPPL) is tackling the world’s toughest science and technology challenges using plasma, the fourth state of matter. With more than 70 years of history, PPPL is a leader in the science and engineering behind the development of fusion energy, a potentially limitless energy source. PPPL is also using its expertise to advance research in the areas of microelectronics, quantum sensors and devices, and sustainability sciences.

Whether it be through science, engineering, technology or professional services, every team member has an opportunity to contribute to our mission and vision. Come join us!

Responsibilities

Core Duties:

Cryogenic and Fluid Systems Operation (70%)

• Operate the control console for the NSTX-U cryogenic plant, maintaining the system within standard operating parameters, and initiating alarm response procedures if operating parameters fall outside normal ranges or if alarms sound.
• Operate NSTX-U experimental water systems include de-ionized treatment systems, HVAC chilled water systems, and tower water systems.
• Review and revise operations procedures.

• Perform maintenance, troubleshooting, and repair of fluid system facilities.
• Able to perform more complex and diversified technical tasks utilizing expertise and knowledge acquired. Typically involving set-up of test apparatus, operation of equipment, and evaluation of the performance and reliability of systems and subcomponents.
• Fabricate parts as required using a variety of equipment and tools such as: milling machine, lathe, drill press, band saw, and other industrial tools.
• Assist in the set up and operation of pneumatic, mechanical, and electromechanical assemblies for various fluids systems applications.
• Work closely with scientific staff, engineers and other technical staff.
• Work may involve radiological activated and contaminated equipment and legacy parts.

• Candidates must have Mechanical Technology or AA degree with 3 to 5 experience; or no degree and 5+ years of general mechanical experience with automotive, industrial or facility mechanical and electromechanical systems operation and maintenance.
