Microwave Design Engineer

Who We Are

At Proxima Fusion, we're driven by a bold mission – to redefine the future of sustainable energy. Our concept is built upon the W7-X stellarator and advances in technology, paving the way for commercially viable fusion power plants. Our work in stellarator optimization, powered by computation and machine learning, is advancing fusion technology with high temperature superconducting magnets enabling higher performance design points. To fully grasp this opportunity, we’re building a team of dedicated and passionate people who bring extraordinary effort to radically transform technology in the world.

WHY JOIN PROXIMA FUSION

• You will work on complex tech challenges to bring abundant, safe, clean energy to the world
• Learn from an exceptional team of accomplished and driven individuals
• Do your life’s best work and enjoy the journey
• Show that big things are possible in Europe when you assemble the best talent

YOUR IMPACT

As a microwave design engineer, you will help build the basis for millimeter wave hardware that initiates a fusion plasma and achieves temperatures above 100 million degrees. You will advance microwave modeling and contribute to the thermo-mechanical design of high-power components, and you will build and test these microwave RF components in the lab before installing them at scale on our Alpha stellarator.

What You Will Do

• Provide innovative solutions to complex microwave radiofrequency engineering challenges by collaborating with physicists to ensure component designs meet Alpha plasma physics and thermal-mechanical constraints.
• Develop designs and evaluate vendor designs to efficiently deliver power to the stellarator, driving down input power to improve fusion power plant gain Q = Pout/Pin and reduce costs.
• Contribute to the stellarator development process by interfacing RF components with other systems.
• Perform mechanical and thermal analysis and sensitivity studies for component viability under vacuum, magnetic fields, temperatures, and MW-scale RF loads.
• Interface with the Alpha project management teams to realize delivery of RF components and meet timelines.

Who You Are

• A highly capable engineer with experience in millimeter waves and MW-scale RF loads; knowledge of high-power microwave design practices and ability to model at 200 GHz to meet thermal, mechanical, and plasma heating goals.
• Familiar with Python scripting and modeling codes such as SURF3D, CST, COMSOL, GdfidL, openEMS, or custom codes; experience with Ansys and Catia is desirable.
• Experience validating first-of-a-kind designs with uncertain performance, working in multi-scale and multi-physics simulations, testing, and prototyping.
• Exceptional communication and interpersonal skills to articulate complex technical concepts clearly and persuasively.
• Experience operating microwave RF components such as gyrotrons, transmission systems, launchers, windows and mirrors.

INTERVIEW PROCESS

• Recruiter Interview (30–45 min)
• Panel Interviews (3 rounds, 60 min each)
• CEO Call (30 min)

At Proxima Fusion, our mission is bold: making limitless clean energy a reality. We value a high-performing, diverse team and believe diversity of thought leads to better ideas, stronger execution, and a resilient team. We care about what you can bring to the table.
