Jobs at Proxima Fusion

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.

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

Lead Proxima Fusion's global communications: manage media relations, executive positioning, and integrated campaigns; translate technical topics into clear narratives; run high-impact media opportunities; manage agencies; collaborate with Engineering, Policy, Finance and Brand to support fundraising, partnerships and policy objectives.

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.

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.

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

Lead end-to-end delivery of site development and infrastructure projects across multiple locations. Translate early-stage concepts into executable plans, manage schedules, budgets, risks, and stakeholders, and integrate site workstreams into the programme baseline. Act as owner-side delivery authority, coordinate with site owners, planning authorities, and consultants, and maintain oversight of developing opportunities and active projects.

Lead end-to-end delivery of assigned capital and infrastructure projects across the Alpha programme and adjacent workstreams. Manage schedule, budget, risks, dependencies, and stakeholders; shape early concepts into fundable plans; coordinate with programme scheduling; build processes and accountability; adapt to shifting priorities and absorb new projects in a fast-paced environment.

Coordinate day-to-day people operations across regions, manage employee lifecycle administration (onboarding/offboarding), maintain SOPs and policies, partner with external providers (payroll/benefits), resolve people queries, track compliance and risks, and identify process improvements using HR systems.

Lead sourcing for complex, supplier-designed technical systems (cryogenics, vacuum, heating, diagnostics, manufacturing equipment). Run RFIs/RFPs, negotiate contracts, define acceptance/testing/warranty terms, manage supplier interfaces, mitigate technical/commercial risks, and improve procurement using digital tools and AI.

Lead procurement for construction, utilities and site development for a fusion demonstrator. Develop sourcing strategies, run RFIs/RFPs, negotiate EPC/EPCM and equipment contracts, manage supplier performance, change orders and commercial risk, and align procurement with permitting, schedules and cross-functional stakeholders.

Lead sourcing and supplier management for advanced manufactured, build-to-print components. Develop sourcing strategies, run RFIs/RFPs, negotiate contracts, industrialize suppliers, manage performance and risks, and collaborate with Engineering and Quality to ensure manufacture-to-specification, first-article qualification, and continuous procurement process improvement using digital tools and AI.

Own full-cycle recruitment for technical and non-technical roles, partner with hiring managers, proactively source passive talent globally, improve and automate recruitment workflows, run TA projects, and ensure an outstanding candidate experience during rapid company growth.

Lead development and maintenance of the Integrated Master Schedule (IMS) for Alpha. Build schedule architecture, integrate federated sub-schedules, identify critical paths, run schedule risk and recovery analyses, support PMO governance and release gates, and drive schedule discipline across internal teams and external suppliers.

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