Established in 2019 and venture-backed in 2023, the company is led by a team of globally recognized fusion scientists with a strong track record of building state-of-the-art stellarator fusion machines, together with veteran business leaders experienced in scaling companies and commercializing energy technologies.\nIf you are searching for the best new ideas and share our vision, join us as a Plasma Diagnostics Summer Intern. This is what you need to know:\nLocation: Knoxville, TN\nSalary: $25-$35/hour, 40 hours per week\nContract: 12-week internship, Summer 2027 (May 24th start date)\nReporting to: Sr. Diagnostic Scientist\nYour role in the mission:\nType One Energy Group, Inc. is seeking a summer intern in Plasma Diagnostic to apply your education and experience in the design and development of plasma diagnostics for a new fusion energy device.\nThis role requires a self-motivated learner who loves being challenged and gaining new skills. The ideal candidate will have experience in physics, specifically plasma physics and fusion energy, but a broad background including physical laboratory, mathematical/computational, engineering, and software is more important.\nKey responsibilities could include:\nApply physical models and numerical analysis tools to guide the requirements for plasma diagnostics.\nCollaborate with computational physicists, experimental physicists, and engineers to develop the conceptual design for plasma diagnostics.\nDevelop the data analysis workflow and algorithms to extract physical information from raw instrument data.\nBuild and test physical diagnostic hardware including optical systems and electronic circuits.\nWhat you'll need:\nSenior-level student pursuing a degree in physics, engineering physics, optics, electrical engineering, data science, astrophysics, or a related field.Rising juniors, seniors, graduate, and PhD students are encouraged to apply.\nExperience with data analysis in python is required. Additional software skills including numerical simulations, optical system design, thermal modeling, electrical schematic/PCB design, SPICE circuit simulation, version control, LINUX, and databases are desirable.\nExperience with plasma physics, fusion energy, or remote sensing will be a bonus.\nHands-on experience working with scientific instruments, microwave/RF systems, optics, lasers, vacuum systems, and/or electronic circuits will be a bonus.\nAbility to receive guidance, work independently, and contribute to a team.\nType One Energy applies proven advanced manufacturing methods, modern computational physics and high-field superconducting magnets to develop its optimized stellarator fusion energy system. Our FusionDirect development program pursues the lowest-risk, shortest-schedule path to a fusion power plant over the coming decade, using a partner-intensive and capital-efficient strategy.\nType One Energy is committed to community engagement in the development and deployment of its clean energy technology.
