WHY JOIN PROXIMA FUSION Impact: Your simulations will directly shape the magnets that enable commercial fusion energy. Ownership: As part of a small, highly technical team, you will define modeling standards and influence core design decisions. Frontier Engineering: Work at the intersection of high-field electromagnetics, cryogenics, and advanced numerical methods. Collaboration: Join a team combining deep superconducting expertise with advanced computational capability to solve one of the hardest engineering challenges of our time. YOUR IMPACT At Proxima Fusion, we are designing the first generation of fusion power plants to provide the world with clean, carbon-free energy. The heart of our reactor lies in its superconducting coils. These magnets operate at cryogenic temperatures, generate extreme magnetic fields, and must remain stable under complex electromagnetic and thermal transients. We are looking for a Numerical Modeling Engineer to develop high-fidelity simulation tools that predict and de-risk the behavior of our superconducting magnets. Your work will span electromagnetic, thermal, and transient multiphysics modeling - including quench dynamics - and will directly inform design decisions for conductors, coils, and protection systems. This role is not about running black-box simulations. It is about building robust numerical frameworks - combining commercial multiphysics tools with in-house developed models - to enable fast, reliable, physics-driven engineering decisions. WHAT YOU WILL DO Your work will combine physics modeling, numerical implementation, and close collaboration with magnet designers and experimental teams. You will contribute across three primary domains: 1.

IN-HOUSE TOOL DEVELOPMENT & NUMERICAL INFRASTRUCTURE Beyond commercial software, you will help build Proxima’s internal modeling backbone. - Custom Solvers & Reduced-Order Models: Develop fast, scalable modeling tools for system-level studies and design iteration. - Automation & Parametric Studies: Build robust pipelines for design sweeps, optimization, and uncertainty quantification. - Code Development: Contribute to internal Python- or C++-based frameworks for magnet modeling and data post-processing. - Verification & Benchmarking: Establish numerical best practices, validation procedures, and cross-comparison between tools. - Scalability: Ensure models can scale from conductor-level physics to full magnet assemblies. Experience with COMSOL or similar commercial multiphysics tools (ANSYS, Opera, etc.) is valuable, but building reliable, physics-based in-house tools is equally (if not more) important. 3. DESIGN INTEGRATION & ENGINEERING DECISION SUPPORT Your models will not live in isolation — they will directly shape hardware. - Design Feedback: Provide quantitative guidance on conductor layout, stabilization strategies, and protection schemes. - Risk Assessment: Identify failure modes and quantify margins under realistic operating scenarios. - Cross-Team Collaboration: Work closely with magnet engineers, quench protection specialists, and test engineers. - Documentation & Communication: Translate complex physics into clear engineering recommendations. WHO YOU ARE We are looking for a rigorous numerical thinker who enjoys bridging fundamental physics and practical engineering. Background: - Degree (MSc or PhD) in Electrical Engineering, Applied Physics, Computational Engineering, or a related field. Core Expertise: - Strong foundation in electromagnetics and physics-based numerical modeling (e.g., FEM, nonlinear coupled systems), with the ability to implement and extend models programmatically - Experience with multiphysics and transient simulations (e.g., electromagnetic–thermal coupling, fast transients). - Proficiency in at least one scientific programming language (Python, MATLAB, C++, or similar), with interest in developing internal modeling tools and workflows. Valued Experience (not all required): - Electromagnetic numerical modeling - COMSOL or other commercial FEM tools. - Modeling of high-current or high-field devices. - Thermal modeling and heat transfer in complex systems. - Experience building internal engineering tools rather than relying purely on GUI-based workflows. Mindset: - You question assumptions and validate results critically. - You are comfortable building models from first principles. - You thrive in a startup environment where tools, processes, and standards are still evolving. Prior experience with superconductors or HTS magnets is a plus - but strong electromagnetic and numerical expertise is the primary requirement.

YOUR IMPACT Alpha will be the first stellarator to achieve net energy. Getting there requires building a deeply coupled machine, where plasma, magnets, structures, cryogenics, heating work as one, and work at the edge of what each discipline can deliver on its own. You will own the complex calculations that set the requirements each system needs to be designed against. You will be accountable for providing the engineering design teams with reasonably estimated and correctly validated load cases that drive the design of the machine. WHAT YOU WILL DO - Own simulation pipelines end to end. From physics assumptions through to the machine-defining load cases you provide the subsystem to teams. You own the whole chain, not a step in it. - Build the simulators. Finite-element models where that's the right instrument, a reduced-order model coded from scratch where it isn't, all of it properly interfaced with our codebase. - Set the interfaces. Define with each engineering team what goes in, what comes out, what it means and what it doesn't cover. - Scan the space. Run parameter sweeps and simulation campaigns at scale to settle machine-level tradeoffs before they're locked in. - Prove the numbers. Benchmark, cross-check against analytical limits and experiment, and know the boundary where your model stops being trustworthy. WHO YOU ARE - You range across physics and geometry. You are not afraid of jumping between Lorentz forces in a stellarator and the 3D geometry. - You've earned that breadth. A PhD or Master's in physics, engineering, or an adjacent field, and time spent where multiphysics analysis actually drives hardware decisions: space, accelerators, semiconductors, aircraft, or anywhere else complex machines get built at scale. - You build in code like an engineer, not a scripter. Git, CI/CD, and the PyData stack are second nature, and you've shipped real software, not a folder of one-off scripts. - You reach for whatever tool fits. Pen and paper, a solver you wrote last night, or a commercial multiphysics package, the method serves the question, never the reverse. - You think in pipelines. Automation, reproducibility, validation. And you can tell when a passing series of tests isn't actually telling the truth. - You're proactive. You find the gap before it becomes a problem, prioritize hard, and argue for the next step.

YOUR IMPACT In a fusion reactor, fusion-born alpha particles play a central role in plasma self-heating and overall reactor performance. Their confinement, transport, and interaction with collective plasma instabilities directly determine whether a burning plasma can remain stable, efficient, and economically viable. At reactor scale, energetic particle driven Alfvénic activity can enhance fast ion losses, exacerbating plasma loads on the first wall and other in-vessel components.

As an Burning Plasma Physicist at Proxima, you will lead efforts to understand, model, and optimize energetic particle behavior in reactor-scale stellarator plasmas. Your work will focus on fast-ion confinement, energetic particle transport, and bulk plasma interactions mediated through Alfvénic activity. You will develop and apply advanced numerical tools to assess alpha particle confinement, characterize instability-driven transport, and guide stellarator optimization toward robust burning plasma operation. This role offers a rare opportunity to shape the physics foundations of a commercial stellarator power plant. Your work will directly influence plasma performance, reactor operating limits, and the ability of future devices to achieve reliable steady-state fusion power. By connecting first-principles plasma physics to reactor design decisions, you will help define the path toward practical burning plasma operation in optimized stellarators. WHAT YOU WILL DO - Lead the development, validation, and application of advanced energetic particle transport workflows for assessing burning plasma physics in reactor-scale stellarator plasmas. - Investigate energetic particle driven instabilities, including Alfvén eigenmodes and related EP–MHD interactions, and assess their impact on plasma performance. - Ensure alpha particle confinement remains within the tolerable limits of plasma facing components under reactor-relevant operational scenarios. - Work closely with stellarator optimization teams to incorporate energetic particle physics constraints into magnetic configuration design. - Develop reduced-order models and analysis workflows to accelerate reactor design studies and scenario optimization. WHO YOU ARE - Hold a postgraduate degree in plasma physics, or a related discipline. - Have strong expertise in energetic particle transport, burning plasma physics, or kinetic plasma instabilities. - Bring experience studying EP–MHD interactions, including Alfvén eigenmodes, fast-ion driven instabilities, or related wave-particle interaction physics. - Have experience using advanced simulation tools for kinetic, orbit-following, gyrokinetic, or hybrid MHD modeling. - Be proficient in scientific programming languages such as Python, Julia, C++, and/or Fortran. - Be comfortable working across disciplines, collaborating closely with physicists and engineers to solve open-ended reactor design challenges. - Take initiative, communicate clearly, and be motivated by solving open-ended physics challenges critical to commercial fusion energy.
