Jobs at Proxima Fusion

As a Senior Recruiter, you'll lead full-cycle recruitment, define hiring needs, engage passive talent, improve workflows, and manage talent acquisition projects during Proxima Fusion's growth phase.

As a Senior Stellarator Design Scientist, you'll design 3D magnetic fields for fusion reactors, balancing physics and engineering for optimal performance.

Join Proxima's Enterprise AI team to discover use cases, build AI solutions in Python, integrate tools, and drive AI adoption across the company.

Proxima Fusion seeks passionate candidates for unsolicited applications to contribute to innovative clean energy solutions and support the development of fusion technology.

Design, analyse, validate and commission cryogenic cooling systems for superconducting magnets in a fusion stellarator. Lead hands-on testing, troubleshooting, supplier coordination, and collaborate with multidisciplinary engineering and physics teams to deliver reliable cryogenic plant performance.

Develop and own code-driven parametric representations of stellarator components, automate CAD-to-mesh-to-simulation pipelines, build differentiable JAX-based geometry and physics models, implement algorithms for custom 3D geometry, and collaborate with cross-disciplinary engineering and physics teams to produce optimisable, manufacturable reactor designs.

Build and operate core developer platform and cloud infrastructure for simulation-driven stellarator design. Responsibilities include cloud infrastructure (IaaC, permissions, efficiency), Kubernetes/Ray/Dask-based compute, CI/CD and developer experience, observability, and managing distributed/HPC clusters while improving DevOps practices and DORA metrics.

Lead strategic sourcing and supplier management for professional and technical services. Own contract negotiations, end-to-end procurement operations, supplier performance, and procurement systems. Drive tool and process improvements (databases, ERP, AI, automation) and collaborate with engineering, finance, legal, and operations to align procurement with company priorities.

As a Neutronics Engineer, you will analyze neutronics for the Alpha stellarator, automate simulations, and collaborate with multidisciplinary teams to enhance fusion technology for clean energy.

Design and develop control architectures and advanced control algorithms for integrated electrical and automation systems. Lead subsystem integration for synchronized plant operation, modernize power management strategies, and implement diagnostics and predictive maintenance to improve reliability and performance.

Develop and validate assembly engineering work packages for a stellarator program, verify supplier data and installation packages, design assembly tools, monitor construction for safety, quality and schedule, and implement safety-critical controls across the supply chain during a 12‑month ITER secondment and subsequent work in Munich.

As the part-time Workplace Experience Assistant, you will support the workplace environment by managing office operations, creating community, and coordinating with services and teams; ensuring efficiency and warmth in the workplace.

As an AI Solutions Engineer, you will design and implement AI-driven automations to enhance workflows and eliminate bottlenecks, collaborating across teams to innovate solutions.

The engineer will develop instrumentation and testing infrastructure for superconducting magnets, focusing on design and software for testing protocols, data acquisition, and advanced sensor innovation.

Develop high-fidelity simulation tools for superconducting magnets, focusing on electromagnetic and thermal multiphysics modeling, tool development, and design integration.

As a Computational Physicist, you'll design and validate simulation tools for fusion plasma behavior, applying state-of-the-art numerical models and modern software practices.

The Mechanical Design Engineer will design components for Proxima Fusion's SMC, develop prototyping and testing plans, and collaborate with suppliers on design improvements.
