YOUR IMPACT
As a microwave design engineer, you will help build the basis for the millimeter wave hardware that acts as the spark plug to initiate a fusion plasma and raises its temperature to greater than 100 million degrees. Join the team to advance our microwave modeling and be a key player in the thermo-mechanical design of high-power components. You will also help build and test these microwave RF components in the lab, before installing them at scale on our scientific breakeven Alpha stellarator.
WHAT YOU WILL DO
Provide innovative solutions to complex microwave radiofrequency engineering challenges by collaborating closely with physicists to ensure the component designs meet the Alpha plasma physics and thermal-mechanical constraints.
Develop designs and evaluate vendor designs to determine an optimal path to efficiently deliver our power to the stellarator - driving down the denominator of input power that will limit fusion power plant gain Q=Pout/Pin - and drive down costs.
Draw from and contribute to our stellarator development process, interfacing your radio frequency components with other stellarator systems.
Perform mechanical and thermal analysis and sensitivity studies for component viability under the loads and stresses imposed by the combination of vacuum, magnetic fields, temperatures, and MW-scale RF loads.
Interface with the Alpha project management teams to realize the delivery of RF components and meet the tight Proxima timelines.
WHO YOU ARE
A highly capable engineer with experience in millimeter waves and MW-scale RF loads. Knowledge of the tools and best practices for designing high power microwave systems and capable of performing and optimizing modeling at 200 GHz frequencies to achieve thermal, mechanical and plasma heating performance goals.
Demonstrated familiarity with python scripting and modeling codes such as SURF3D, CST, COMSOL, GdfidL, openEMS or custom developed codes for millimeter wave design. Experience with mechanical design analysis and design tools such as Ansys and Catia are also desirable.
Experience validating first-of-a-kind designs with uncertain performance, working as part of a team on multi-scale and multi-physics simulations, testing, and prototyping.
Exceptional communication and interpersonal skills, with the ability to articulate complex technical concepts clearly and persuasively.
Experience operating microwave RF components such as gyrotrons, transmission systems, launchers, windows and mirrors.
