Jobs at Proxima Fusion

Own business development opportunities from market scanning through leadership go/no-go decisions, initially focused on acquisitions, minority investments, and joint ventures. Build market reports, competitive landscapes, company mappings, business cases, valuations, and decision memos. Lead expert calls, reference checks, and data-room screening while collaborating with engineering, finance, legal, and supply chain teams. Source new opportunities through industry events and apply AI tools to accelerate research, screening, and drafting.

Develops FPGA-based control and protection systems for fusion plasma heating hardware. Responsibilities include HDL design and verification, embedded software and firmware development, FPGA-peripheral integration, CI/CD pipeline creation, and software-in-the-loop and hardware-in-the-loop testing. The role also establishes reusable FPGA architectures, workflows, testing methods, and HDL best practices while collaborating with RF, controls, electronics, and systems teams.

Design and develop manufacturing equipment, fixtures, tooling, and processes for superconducting magnet coils. Responsibilities include CAD design, tolerance analysis, BOMs, drawings, assembly documentation, commissioning, technician support, troubleshooting, root-cause analysis, DFM/DFA, vendor coordination, and production scaling. The role combines hands-on equipment development with mechanical design from concept through production readiness.

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.

Own cybersecurity engineering for a fusion company’s digital and physical environments. Responsibilities include operating SIEM and incident response, hardening endpoints, identity, networks, and infrastructure, maturing Zero Trust, securing Google Workspace and software supply chains, managing vulnerabilities, supporting compliance audits, and establishing physical security standards across locations.

Develop and execute procurement strategies for highly technical components, services, and first-of-a-kind builds. Manage supplier identification, assessment, onboarding, negotiations, risk, cost, quality, and delivery. Oversee end-to-end procurement operations, improve procurement systems and automation, collaborate with engineering, finance, and operations, and support early product development and prototyping.

Supports the CEO, Chief of Staff, and Personal Assistant by owning critical projects, preparing leadership and investor materials, improving information flow, coordinating priorities, and building scalable systems. The role also identifies inefficiencies, applies AI and digital tools, manages special projects, and helps optimize executive time and company-wide communication across multiple locations.

Lead Proxima Fusion’s site development portfolio across multiple projects, coordinating feasibility, schedules, budgets, decision gates, stakeholder relationships, permitting, infrastructure scaling, risks, and senior leadership reporting. The role requires managing complex greenfield or brownfield energy or industrial sites through final investment decision, particularly in highly regulated environments. Success requires strong program governance, stakeholder diplomacy, technical coordination, and fluency in German and English.

Develop embedded control platforms for power electronic converters, including controller architecture, microcontroller, DSP and FPGA selection, real-time software, target-hardware debugging, testing and validation. Translate control requirements into deterministic implementations and collaborate with power electronics, electronics, mechanical, thermal and systems engineers. The role also explores improved embedded architectures and supports automated, hardware-in-the-loop and safety-critical testing approaches.

Designs and develops PCB-based electronics for power converters, including gate drivers, sensing, signal conditioning, protection, auxiliary power, and DC-link balancing circuits. Responsibilities span circuit architecture, component selection, simulation, schematic and PCB design, prototyping, laboratory testing, troubleshooting, verification, validation, and integration with power electronics, embedded software, mechanical, thermal, and systems engineering teams.

Lead the team responsible for the architecture, design, and integration of facility-wide monitoring and control systems for a commercial stellarator fusion plant. Own supervisory control software, telemetry, live monitoring, facility data infrastructure, functional safety strategy, physical infrastructure integration, control hardware R&D, and subsystem interface standards. Build high-performing teams and translate complex, safety-critical R&D into reliable operational systems.

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

Design, develop, and maintain software platforms for stellarator simulation and design. Automate large-scale simulation workflows, manage cloud-based data storage, build web applications for collaboration and discovery, and integrate AI tools. Work closely with researchers to apply simulation tools, guide users, and co-develop applications that accelerate fusion R&D.

Provides administrative support to the Leadership Team by coordinating calendars, booking travel, arranging logistics, tracking expenses, preparing meeting documents, taking notes, and managing recurring internal meetings. The role requires strong organization, discretion, reliability, communication, flexibility, and proficiency with productivity tools in a fast-paced environment.

Develop and industrialize manufacturing processes for high-temperature superconducting magnet coils. Responsibilities include designing and validating tooling, fixtures, assembly sequences, work instructions, process controls, inspection methods, and quality systems. Lead prototype builds, NPI campaigns, process trials, root-cause analysis, supplier qualification, engineering change control, and the transition from prototype to serial production. Collaborate with design, materials, quality, supply chain, and test engineering teams in a high-precision manufacturing environment.

Own controls engineering for new magnet manufacturing equipment, including control architecture, Beckhoff PLC software, field networks, servo drives, HMIs, safety systems, commissioning, testing, troubleshooting, and documentation. Collaborate with mechanical, process, electrical, and manufacturing engineers to develop reliable automation solutions for coil winding, impregnation, joining, and end-of-line testing.

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.

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.

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