We are seeking a Scientist (Experimental Plasma Physicist) who will develop in-situ boundary plasma diagnostics for the C-2W fusion device. In this role, you will design, deploy, and troubleshoot direct-contact material diagnostics - such as Langmuir probes, retarding field analyzers, fast ion loss detectors, pyrobolometers, and thermo-optical arrays - to measure local edge density, temperature, heat flux, and more. You will also run experiments, perform data analysis, and translate raw diagnostic signals into physics-based insights. This is a full-lifecycle scientific role. We are not just looking for a hardware builder, but a scientist who will own the entire experimental loop. You will lead the physical development of edge diagnostics, deploy them on the C-2W device, run the experimental campaigns, and critically analyze the resulting data to gain insight into the underlying physics and help guide design choices for our next-generation devices. About The Role - The successful candidate will join the Boundary Plasma Physics Team in the Applied Plasma Physics Division under the guidance of the Lead Scientist. - Develop, deploy, refine, and troubleshoot in situ boundary plasma diagnostic systems to characterize key plasma parameters such as local edge density, temperature, heat flux, plasma potential, fast ion distribution, and more. - Collaborate with engineering teams to design, maintain, and refine direct-contact material diagnostics - such as Langmuir probes, retarding field analyzers, fast ion loss detectors, pyrobolometers, and thermo-optical arrays. - Plan and execute experiments on the C-2W fusion device. - Analyze complex experimental data with advanced modeling and simulation tools, interpreting results within the broader fusion research program. - Prepare technical reports, documentation, and presentations for internal meetings, project reviews, and scientific conferences. - Maintain laboratory infrastructure while strictly following all safety protocols. - Promote the TAE Core Values, Rules of the Road, and our Culture of Safety. About You - PhD-level research experience in experimental plasma physics, with a strong focus on in situ plasma diagnostics. - Hands-on experience building, deploying, troubleshooting, and maintaining diagnostics on plasma research devices - Direct experience with one or more of the following diagnostics highly preferred: Langmuir probes, retarding field analyzers, pyrobolometers. - Demonstrated success in planning and conducting experiments, analyzing results, extracting physics-based insights, and delivering technical reports or peer-reviewed publications. - Experience with scientific programming, data analysis, and data visualization using Python (preferred) or similar tools. - Experience working with standard plasma diagnostic instrumentation and plasma research device infrastructure, including but not limited to: DAQ systems, motorized actuators, power supplies, oscilloscopes, function generators, multi-meters, high-vacuum systems. - Strong analytical and problem-solving skills with the ability to interpret complex datasets. - Excellent written and verbal communication skills for multidisciplinary collaboration. - Ability to work effectively both independently and in team environments to meet project objectives and deadlines. Education - Required: Ph.D. in Plasma Physics, Engineering, or a closely related field.
