We are applying science and engineering to design transformational technologies. Whether it's harnessing fusion through the science of stars, making exponential leaps in power efficiency, or innovating medical care with a novel cancer treatment: We're turning the promise of science into reality.\nWe’re looking for candidates who are passionate about realizing our mission: A future where all people have affordable access to reliable, abundant, and environmentally friendly fusion-generated electricity.\nAbout The Role\nThe next fusion machine in TAE - Da Vinci, requires a powerful NB injecting system. It has two types of the neutral beams - low energy NB (tens of keV, 5 MW per beamline), based on positive ions source and high energy NB (1 MeV, 5 MW), based on negative ions source.\nYou will participate in development of the long pulse plasma sources (CW), extracting and accelerating systems, beamline components; conduct experiments with the plasma source and beam characterization; do plasma generation and beam transport simulation.\nThe key accountabilities\nConduct low temperature plasma experiments, do simulations of the plasma generation\nDevelop/study/optimize ion beam optics\nDevelopment of the new NB for the future plasma machine: simulations - beam formation, transport; beam parameters experimental characterization, design NB systems together with the engineering team, carry out experiments to test NB subsystems.\nDevelopment of the beamline systems - vacuum systems, beam dumps, neutralizers, etc.\nDevelopment diagnostics for the high-power NB (Secondary electron emission detectors, calorimeters, optical diagnostics, etc.)\nAbout You\nHave worked with the following: Plasma sources, Neutral beam injectors. Experience in designing and operating plasma/beam diagnostics\nIon/electron accelerators, beam transport\nOperation of high voltage equipment (>10 kV)\nNumerical simulation of the plasma generators, ion/electron beam formation, beam transport, mechanical/thermal tensions.\nHigh vacuum systems, UHV\nNegative ions sources\nExcellent analytical and data analysis skills.\nExperience in ion beams operation/development/design. Preferred hands-on negative ions beam operation\nExperience with various Programming Languages/Scripts/Macros as well as systems such as Python, Matlab or IDL is also useful.\nEducation\nPhd Required: preferred in physics, plasma physics, engineering or related field\nAt TAE Technologies, we consider a wide range of factors when making compensation decisions including but not limited to skill sets; experience and job-related knowledge, training; licenses and certifications, and other business and organizational needs. The total compensation package for this position may also include other elements depending on the position offered . Salary Range offered for this position: $140,000 - $160,000\n##Hybrid\nAbout Us\nImagination, skill, and will\n#Hybrid\nWe are a diverse team of over 500 engineers, scientists, professionals, Maxwell Prize winners, and big thinkers from more than 40 countries with a track record of delivering on the innovative ways science can lead humanity into a brighter era. We are not afraid to envision a future where fusion and science can transform our world.\nWhat you’ll get with us\nGenerous benefits such as Medical, Dental, Vision, 401 (K) with company match, paid vacation + sick time, companywide December holiday, wellness program, parental leave\nPayment rewards: For referring talent, novel research, and patents\nA collaborative environment: An organization where talents and interests can plug in to different groups throughout the organization\nPotential for equity participation\nHQ in Southern California\nEmployee events on and off-site\nA commitment to upholding and growing an inclusive organization\nLearn more\ntae.com\nOur podcast Good Clean Energy\nInstagram\nLinkedIn\nTAE Technologies is an Equal Opportunity Employer. All applicants will be considered for employment without attention to race, color, religion, sex, sexual orientation, gender identity, national origin, veteran, or disability status.\nWe ensure all individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process, perform essential job functions, and receive other benefits and privileges of employment.
