Power Electronics Engineer – Fusion Systems

At nT-Tao, we are building a compact magnetic confinement fusion power system: a modular, repeatable unit designed to deliver clean electricity on-site, on- or off-grid. Getting there means solving hard, open problems in plasma physics, and that is the work our physicist's lead.

Founded in 2019, nT-Tao raised $34 million to date from Honda, East X Ventures, Delek US, NextGear Ventures, and others. The Israel Innovation Authority has awarded us repeated grants, most recently to build our next compact fusion demonstrator.

Position Overview

We are looking for a hands-on Power Electronics Engineer to join our multidisciplinary R&D team and take an active role in the design, development, integration, and commissioning of high-power and pulsed-power systems for our fusion prototypes and laboratory infrastructure.

You will be involved in developing advanced power electronics systems operating at high voltages, high currents, and demanding pulsed conditions.

You will work closely with physicists, mechanical engineers, software engineers, and laboratory teams, taking systems from initial requirements and conceptual design through detailed engineering, manufacturing, testing, and experimental operation.

Key Responsibilities

• Design, develop, and commission high-power and pulsed-power systems operating at tens of kV, tens of kA, and multi-MW peak power levels.
• Design power converters, inverters, charging systems, switching circuits, capacitor banks, and energy-storage systems.
• Develop gate drivers, control circuits, protection systems, and supporting electronics for high-power switching applications.
• Design and integrate power electronics systems driving magnetic coils, inductive loads, and other experimental equipment.
• Perform electrical circuit analysis, simulations, component selection, and system-level optimization.
• Design and develop PCBs, including high-voltage, high-current, and control electronics.
• Select and evaluate power semiconductor devices, magnetic components, capacitors, and other electrical components.
• Take an active hands-on role in prototype assembly, integration, commissioning, testing, troubleshooting, and optimization.
• Collaborate with physics, mechanical engineering, software, and laboratory teams to support experimental operations and system integration.
• Prepare electrical schematics, design documentation, BOMs, technical specifications, and test reports.
• Support the transition from experimental R&D prototypes toward reliable, scalable, and manufacturable power electronics systems.

Required Qualifications and Skills

• B.Sc. or M.Sc. in Electrical Engineering.
• 4+ years of experience in power electronics design and development.
• Strong understanding of power electronics fundamentals, including switching converters, inverters, power semiconductor devices, and circuit analysis.
• Familiarity with power semiconductor technologies such as MOSFETs, IGBTs, SCRs, SiC, or GaN devices.
• Experience with power conversion, gate driving, protection circuits, and control electronics.
• Understanding of magnetic components, including transformers and inductors.
• Experience with PCB design, electrical schematics, and component selection.
• Experience using circuit simulation tools such as LTspice, PSIM, PLECS, or similar software.
• Proven hands-on capabilities in circuit assembly, testing, debugging, and troubleshooting.
• Good communication, documentation, and teamwork skills.

Advantages

• Experience with resonant converters, soft-switching techniques (ZVS/ZCS), and high-frequency power conversion.
• Experience designing high-power inverters and drivers for inductive or resonant loads.
• Experience with high-voltage insulation, electrical clearances, parasitic inductance, and electromagnetic interference (EMI/EMC).
• Experience with RF power systems, impedance matching, or high-frequency power electronics.
• Experience with MATLAB, Python, or similar tools for simulation, automation, and data analysis.
• Experience working with suppliers, subcontractors, and manufacturing partners.
