Senior Pulsed Power Engineer

The planet urgently needs safe, reliable, zero-carbon energy without waste. Nuclear fusion can address the scale of this problem, but for decades, existing fusion approaches have not proven a net positive energy gain. Zap Energy has rethought the fundamental technology of fusion. As the only company using sheared-flow-stabilized Z-pinch, we present potentially the fastest path to commercially available fusion energy.

Zap Energy is looking for a Pulsed Power Engineer to join our team in Everett, WA. This is a full-time, on-location position.

• Design and develop high-voltage pulsed power systems including capacitor banks, Marx generators, pulse forming networks with best practices and standards for reliable performance.
• Create simulation models and perform electromagnetic analysis using tools such as SPICE, ANSYS, or other to optimize energy storage and discharge characteristics
• Conduct high-voltage and high-current testing and analyze waveforms, rise times, and energy delivery performance
• Develop and implement diagnostic systems and measurement techniques for characterizing pulse parameters
• Troubleshoot system failures, perform root cause analysis, and implement design improvements to enhance reliability and performance
• Design insulation systems, shielding, and safety interlocks for high-voltage applications
• Research and evaluate new materials and technologies for advanced pulsed power systems
• Write technical documentation, test reports, and design specifications
• Collaborate with cross-functional engineering teams on system integration and product development
• Ensure compliance with high-voltage safety standards and regulatory requirements
• Mentor and guide other pulsed power engineers and support in their design and development.
• Follow established development processes and workflows and use industry best practices.

• BS or MS in Electrical Engineering, Engineering Physics, Applied Physics or similar
• 10-15 years experience with pulsed power/high voltage electronics design and testing
• Experience with high voltage pulsed power systems (50kV+, 100kA+, 10’s ns – 100us’s) and architectures including Marx generators, LTD, high energy capacitor banks
• Familiarity with typical pulsed power components such as spark gap switches, thyristors, capacitors and other high voltage, high current components and materials
• Deep understanding of energy storage, transmission line theory and impedance matching
• Understanding of pulsed power diagnostics such as Rogowski, high voltage probes, b-dot / magnetic probes
• Familiarity with 3D FEA modeling tools for electrostatic, transient dynamic, and circuit modeling
• Proficiency with Ansys Maxwell 3D
• Experience with high voltage safety equipment and procedures such as safing capacitor banks, discharge and grounding sticks, high voltage energy dump systems
• Knowledgeable in various insulating systems including vacuum, pressurized insulating gas like SF6, breakdown in air, and insulating materials like polymers and ceramics
• Demonstrated experience of strong troubleshooting skills and understanding of signal integrity, EMI, grounding and shielding.
• Competency with typical electronics bench tools such as oscilloscopes, probes, signal generators, high voltage power supplies, impedance analyzers

• Familiar with PCB development and tools such as Altium or KiCad, PCB manufacturing, and PCB testing
• Experience with control systems
• Programming in Python, C, or NI LabVIEW
• Familiar with power electronics and switch mode power supplies
• Experienced using solid modeling tools like Solid Works

Estimated salary range: $,000 annually.

Zap Energy also offers the following:

• Competitive compensation
• Matching retirement contributions
• Flexible vacation and paid company holidays
