Scientist - Plasma Diagnostics

TAE is the world’s first private fusion energy company, founded in 1998 to commercialize the cleanest, safest, most affordable, and sustainable form of carbon‑free power. We apply 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.

We’re looking for candidates passionate about realizing our mission: a future where all people have affordable access to reliable, abundant, and environmentally friendly fusion‑generated electricity.

Scientist (Experimental Plasma Physicist) – Develop in‑situ boundary plasma diagnostics for the C-2W fusion device. 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. Run experiments, perform data analysis, and translate raw diagnostic signals into physics‑based insights.

This is a full‑lifecycle scientific role, owning the entire experimental loop: develop edge diagnostics, deploy on C‑2W, run campaigns, and analyze data to guide design choices for next‑generation devices.

• 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.
• 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.

• 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 Langmuir probes, retarding field analyzers, pyrobolometers. (Highly preferred)
• 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 DAQ systems, motorized actuators, power supplies, oscilloscopes, function generators, multimeters, 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.
