The role involves designing, building, and sustaining test configurations for performance verification of prototype components and systems, as well as installing, commissioning, and operating high voltage equipment for the MPEX project.

Responsibilities

• Monitor and maintain specialized components and systems during and after commissioning.
• Participate in installation, testing, and commissioning of RF electrical test systems.
• Assemble, test, certify, and document RF test configurations, assemblies, and components.
• Set up, operate, and calibrate various RF test equipment and apparatus.
• Calibrate and ensure the integrity of electrical equipment, personal protective equipment (PPE), and procedures.
• Support development of procedures and documentation related to design, fabrication, testing, and operation of electrical, mechanical, and vacuum systems and their components.
• Assist in documenting records for assembly, testing, and qualification.
• Use computers to collect, record, and analyze data for accepting, operating, and maintaining electrical systems.
• Maintain a strong commitment to laboratory values, safety, and ethics.

Requirements

• BS degree in electrical engineering or a related technical field.
• Five or more years of experience with complex electronics or industrial electric systems.
• Familiarity with electrical systems, components, instrumentation, and associated test equipment.

Qualifications

• Familiarity with office automation tools (e.g., word processing, spreadsheets, databases).
• Strong written and oral communication skills.
• Willingness to learn new skills as needed to perform the job effectively.
• Motivated self-starter with the ability to work independently and collaboratively in teams.
• Understanding of electrical schematics and system architecture to analyze and improve test coverage.
• Familiarity with electrical safety procedures and PPE for testing and troubleshooting electrical equipment.
• Experience with design and execution of electrical hardware testing, including ground resistance and complex functional testing.
• Strong familiarity with operation of equipment and components at voltages greater than 480 V.
• Experience with radio frequency equipment and components at frequencies from 1 MHz to 100 GHz and power levels approaching 500 kW.
• Familiarity with fusion-relevant electron heating and ion cyclotron heating sources.

Special Requirements

• Work involves various physical requirements and working conditions; a pre-hire physical will be required after offer.
• This position requires the ability to obtain and maintain an HSPD-12 PIV badge.
