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 Plasma Fueling & Wall Conditioning Scientist contributes to the Particle Control Group within TAE's Experimental Section. The group is responsible for developing and maintaining plasma fueling systems, implementing particle recycling control techniques (such as gettering and glow discharge cleaning), and designing and analyzing experiments related to particle transport. The group includes staff scientists with expertise in fueling, wall conditioning, and experimental design.\nIn this role, the Scientist contributes individual scientific research and technical work within the group, working under the technical direction of the Lead Scientist. This is an individual-contributor position with room to grow technical depth and leadership within the group over time.\nSupport the development, operation, and continuous improvement of plasma fueling systems (e.g., cold gas injection, pellet injection), including fueling system topology and best practices.\nSupport and maintain wall conditioning systems for particle recycling control, including titanium gettering and glow discharge cleaning systems.\nDesign and execute experiments focused on particle transport, wall conditions, and plasma-material interactions.\nProvide regular analysis and reporting of system data (e.g., vacuum conditions, fueling efficiency, wall conditioning effectiveness); contribute to scientific publications.\nCollaborate closely with other members of the Particle Control Group and across technical groups in a matrixed project environment.\nContribute to the planning and design of future fusion devices, such as Da Vinci, with a focus on fueling and plasma-wall interface strategies.\nMaintain responsibility for test stands within the group's scope, ensuring alignment with experimental objectives.\nOccasionally represent TAE in external settings such as conferences, collaborations, or recruiting events.\nPromote and embody TAE's Core Values, Rules of the Road, and Culture of Safety.\nAbout You\nWe welcome applications from recent Ph.D. graduates as well as candidates with postdoctoral or industry research experience. We prioritize candidates who bring depth of expertise, at a lead-researcher level, in at least one or two of these areas, along with working familiarity across the rest:\nPlasma scientific research, including laboratory experiments, diagnostics, and data analysis\nRequired: experience with high-vacuum lab equipment\nCondensed matter physics, atomic physics\nPlasma fueling systems such as puff valves, pellet injectors, or neutral beams\nWall conditioning techniques such as glow discharge cleaning, evaporable gettering, or machine baking\nPlasma-wall interactions\nParticle transport experiments, modeling, or analysis\nOther Preferred Experience:\nExperience contributing to or helping coordinate large-scale scientific projects and/or collaborations\nTechnical Experience (Equipment, tools, etc.):\nUnderstanding of the application of tools, test equipment, and process control such as high voltage power supplies, voltmeters, oscilloscopes, ionization gauges\nUtilization of pneumatics and high speed gas valves\nExperience with cryogenics is preferred\nSoftware Knowledge and Skills:\nMS Office Suite\nExperience with project collaboration platforms and document management systems preferred\nExperience with scientific analysis languages (Python, Matlab, IDL, etc.) preferred\nEducation\n Required: Ph.D. in Physics or a closely related field (new graduates welcome to apply)\n Preferred: Postdoctoral research experience in plasma physics or a closely 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 (non-Sr., Sr., Lead or Manager). $115,000 - $140,000 (indicative range for an individual-contributor Scientist level - adjust to your internal bands)\nAbout Us\nImagination, skill, and will\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: tae.com | Our podcast Good Clean Energy | Instagram | LinkedIn\nTAE Technologies is an Equal Opportunity Employer.
