In parallel, we are developing the key components required to build affordable fusion systems.\nOur plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand. You can read more about us in this letter from our founders.\nWhy This Role Matters\nWe are seeking a highly motivated Mechanical Engineer to design, build, operate, and advance our pulsed power systems - the core of our experimental fusion platform. This role is deeply hands-on and multidisciplinary, requiring expertise across high-voltage systems, controls, diagnostics, and data analysis. The ideal candidate combines strong technical depth with the ability to lead R&D workflows, collaborate across disciplines, and take ownership of system performance and development.\nDesign, build, and operate pulsed power systems, including high-voltage and high-current architectures, control systems for pulsed power operation, safety, and automation.\n\nOperate pulsed power systems during testing and data acquisition campaigns, including occasional work outside regular business hours.\n\nEnsure safe, reliable operation of high-energy systems in accordance with company safety protocols.\n\nAcquire, process, and analyze data from pulsed power experiments to evaluate system performance and stability.\n\nDevelop tools and workflows for data collection, visualization, and interpretation.\n\nTranslate experimental results into actionable insights for next-generation pulser design.\n\nTake ownership of pulsed power subsystem advancement and roadmap execution.\n\nLead design reviews, experimental planning, and technical documentation.\n\nCollaborate with mechanical, electrical, and plasma physics teams to iterate and improve designs.\n\nDrive continuous improvement in reliability, efficiency, and diagnostic capability.\n\nWhat You Bring\nBachelor’s degree in Mechanical Engineering, Applied Physics, or a related field.\n\n2+ years of demonstrated experience designing complex systems.\n\nExperience designing, developing, testing and building prototype mechanical/electrical systems.\nProven ability to deliver complex R&D projects on schedule, from concept to prototype to validation.\nStrong background in electronic design, control systems, and PLC software development.\n\nProficiency in circuit simulations (e.g., SPICE, PSCAD, COMSOL, or similar) and data analysis using Python, MATLAB, or equivalent tools.\n\nFamiliarity with engineering modeling and CAD software (e.g., SolidWorks, ANSYS, or COMSOL Multiphysics).\n\nBonus Points For\nAdvanced degree (M.S. or Ph.D.) in Mechanical Engineering, Applied Physics, or a related field.\n\nPrior experience with high-voltage pulsed systems for fusion, plasma research, or accelerator applications.\n\nHands-on experience integrating diagnostics and controls for high-energy experiments.\n\nKnowledge of safety standards and best practices in high-voltage or high-energy environments.\n\nPay Range:\n$130,000—$180,000 USD\nTOTAL COMPENSATION AND BENEFITS FOR ELIGIBLE EMPLOYEES\nIndustry-competitive salary\n\nEquity plan\n\n6% employer 401k matching\n\nGenerous paid time off (including sick leave, vacation, paid family leave)\n\nMedical, Dental, and Vision insurance\n\nActual base salary offered will be determined by: experience, skills, and work location. This range is for base salary, our total compensation includes equity and benefits. We welcome you to apply even if your expectations are outside our listed range. \nEQUAL OPPORTUNTITY\nPacific Fusion is committed to creating a diverse environment and is proud to be an Equal Opportunity Employer.
