Jobs at Proxima Fusion

Supports the Partnerships and Public Affairs team by coordinating public grant applications, translating technical inputs into partner documents, mapping industrial partners, and developing AI-powered workflows for CRM enrichment, meeting notes, reporting, and supply-chain processes. The intern will own small end-to-end projects and help strengthen communication across technical and business teams.

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.

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.

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.

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.

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 delivery and technical integration of megawatt-level plasma heating systems for the Alpha stellarator. Evaluate vendor proposals, coordinate partners, ensure RF and particle source performance, integrate heating subsystems with the wider stellarator design, and support supplier strategies for future commercial systems.

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.

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 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.

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.

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.

Lead owner-side commercial and contracts for a first-of-kind fusion demonstrator. Build contractual frameworks, negotiate major contracts, translate technical scope into contract language, coordinate commercial governance across procurement and engineering, support PMO on cost controls, and monitor contract performance to mitigate programme risk.

Lead system-level architecture for a first-of-a-kind stellarator power plant, integrate plasma, magnets, cryogenics, and controls; close design loops with subsystem teams, quantify model uncertainties, run first-principles and reduced-order studies, and turn analyses into actionable engineering decisions to optimize performance, margin, and cost.
