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\nThis position will coordinate and participate in the design and fabrication of various systems and equipment used in the referenced fields.\nThe ability to use depth of mechanical engineering knowledge and experience to develop cutting edge technology is the objective. More detailed required and desired skills are described below.\nThis position will be responsible for the coordination and delivery of significant, high value systems/sub-systems.\nCollaborate with Engineering, Physics and Operations groups to clarify and define requirements\nDevelop mechanical systems and designs that satisfy requirements.\nCoordinate and organize design reviews\nContribute subject matter expertise to the team\nOrganize multidisciplinary project teams and make estimates for cost and schedule\nCoordinate with electrical, controls, design engineers and engineering analysis staff\nWrite and/or review specifications and procedures\nLocate and select qualified manufacturers\nFollow fabrication and delivery of components\nParticipate in installation and commissioning activities\nSome limited travel required\nAbout You\nB.S., M.S. or Ph.D. in Mechanical Engineering or closely related field.\nPhysics, Aerospace, and Electrical Engineering would be considered favorably as dual major degrees, supplementary education or as alternatives to Mechanical Engineering for an especially well qualified candidate.\nApproximately 10 years of relevant experience in large component design and fabrication for technical industries such as aerospace, nuclear, automotive, petroleum processing, proton therapy, national laboratories, or similar is typical for this role. This is a guideline rather than a fixed threshold: candidates with fewer years but strong alignment with the desired skills described below are encouraged to apply, and candidates newer to some of these disciplines may be considered for a developmental path into the role.\nExperience in a research and development environment.\nThorough knowledge of engineering fundamentals including basic physics, electromagnetism, statics/dynamics, basic circuit theory, structural mechanics, controls, thermodynamics, fluid dynamics, heat and mass transfer.\nAbility to respond flexibly to discovery of new requirements. Much of the work at TAE involves research so change is expected thus the inherent ability to change designs/approaches as the need arises is essential.\nPreferred Qualifications\nExperience with project organization tools such as Microsoft Project, Jira, Confluence, or other project management tools and working knowledge of basic Project Management principles would be considered very favorably.\nAbility to coordinate team meetings and prepare/deliver technical presentations to both large and small groups would be beneficial.\nMedical Device or aerospace engineering and design process implementation experience\nFinite element analysis (FEA) familiarity (structural static, dynamic, electromagnetic, fluids/CFD, particle tracking, etc)\nCryogenics engineering experience\nExperience with flow systems undergoing phase change\nExperience in the design of electromagnets, up to and including superconducting devices\nBasic understanding of high voltage electrical systems\nHigh or ultra-high vacuum system experience (electropolishing, outgassing, cleaning processes, cryopumps, turbopumps, backing pumps, metal seals, getter systems, gate valves, etc.)\nPiping system engineering experience (for air, nitrogen, argon, helium, hydrogen, cryogenics, etc.)\nExperience with high power RF system design\nExperience with particle accelerator systems (electrostatic, linear, synchrotrons, cyclotrons, etc.)\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.,). The compensation range for these roles are $135,000 - $150,000.\n#LI-Onsite\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\ntae.com\nOur podcast Good Clean Energy\nInstagram\nLinkedIn\nTAE Technologies is an Equal Opportunity Employer.
