Design and Engineering
Overview:
We are seeking an Engineer to design and develop high pressure systems for filling inertial fusion energy (IFE) targets with deuterium tritium gas (DT). This will span prototypes to mass production systems where target throughput is at a few Hertz rate. Fill pressures in the range of two to three hundred atmospheres are expected. Mechanisms operating in this pressure environment are anticipated. The filling system will form a key component for fueling the Inertia fusion power plant.
Primary Responsibilities:
Design and develop high pressure systems for filling IFE targets with DT gas.
Develop, implement, and document safety protocols, and standard operating procedures for the high-pressure filling system.
Develop tests to evaluate filling system performance and analyze test results
Assist with other power plant pressure projects such as power conversion cycle.
Qualifications:
Required:
PhD or MS, or experience equivalent, in Engineering, Applied Physics, Physics, or related field.
Demonstrated ability to design and develop complex high-pressure systems.
Familiarity with hazardous material safety protocols,
Strong analytical data/measurement skills.
Preferred:
Experience the design, development, and operation of tritium systems.
Experience design and development of mechanical systems operating in high pressure, and automated movement of product into and out of a high pressure environment.
Experience with FMEA and reliability engineering.
Knowledge of the ASME Boiler and Pressure Vessel Code
Salary & Benefits:
We offer an excellent benefits program, including Medical, Dental, and Vision plans, company-paid holidays, matching 401k, and more!
About Inertia:
Inertia is taking the most direct, scientifically-proven path to commercializing fusion, leveraging the only successful achievement of fusion ignition, using a process that was pioneered at the U.S. Department of Energy’s (DOE) Lawrence Livermore National Laboratory (LLNL). With groundbreaking innovation, transformative technology, and multi-year investment, Inertia is committed to commercializing fusion energy in the next decade.
