Microwave Design Engineer

YOUR IMPACT

As a microwave design engineer, you will help build the basis for the millimeter wave hardware acting as the spark plug that initiates a fusion plasma and raises its temperature to greater than 100 million degrees. You’ll join the Alpha Heating System team ready to drive the integrated RF and thermo-mechanical design of high-power components, and help build and test these components in the lab before installing them at scale on our net scientific gain Alpha stellarator.

WHAT YOU WILL DO

• Provide innovative solutions to complex RF engineering challenges by collaborating closely with physicists to ensure 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 RF components with other stellarator systems.
• Contribute to 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 RF engineer with experience in millimeter waves and knowledge of the tools and best practices for design of these systems
• Demonstrated familiarly with RF modeling codes - SURF3D, CST, COMSOL, GdfidL, openEMS, even self-developed python codes or ones plasma physics community hasn’t heard of - capable of performing modeling at 200 GHz frequencies
• 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 with gyrotrons and associated components - transmission systems, launcher antennas, rf loads; experience with plasma physics is a plus.
• Understanding of quasi optical propagation of millimeter waves; ray tracing and where it breaks down

INTERVIEW PROCESS

• Recruiter Interview (30-60 min)
• Technical Screening (30 min)
• Technical Panel (3x60 min)
• This role sits at "L2-L3" of our framework, please inquire during the recruitment process for further information.

At Proxima Fusion, our mission is bold: making limitless clean energy a reality. To get there, we need a high-performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose. We know that diversity of thought and experience leads to better ideas, stronger execution, and a more resilient team. We don’t look at how you identify, what you look like, who you choose to worship or what ethnicity you are. We care about what you can bring to the table.
