Job description

Job Details

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 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.

We’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.

The Scientist (Experimental Plasma Physicist) will develop, implement, and oversee advanced diagnostic systems focused on radiation and fast ion physics for the C-2W fusion device. This role involves designing and operating advanced spectroscopic systems (including Doppler spectroscopy, charge-exchange recombination spectroscopy, filtered PMT arrays, visible Bremsstrahlung, and fast imaging), X-ray detectors, and fast ion / fusion product diagnostics (proton and neutron detectors, fast ion loss detectors, and neutral particle analyzers).

About The Role

• The successful candidate will join the Radiation and Energetic Particle Physics Team in the Applied Plasma Physics Division under the guidance of the Lead Scientist.
• Develop and refine diagnostic techniques to characterize key plasma parameters such as fast ion distributions, electron dynamics, thermal ion and neutral properties, radiation profiles, and energetic particle modes.
• Collaborate with engineering teams to design, implement, and maintain detector systems, optical setups, vacuum hardware, and associated instrumentation.
• 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.
• Contribute to the design and testing of new or upgraded diagnostic systems in collaboration with scientists and engineers.
• 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

• 2-5 years post-PhD experience in experimental plasma physics, with a strong focus on radiation and fast ion diagnostics or closely related fusion diagnostics.
• Demonstrated success in planning and conducting experiments, analyzing results, and delivering technical reports or peer-reviewed publications.
• Proficiency with plasma diagnostic instrumentation, optical systems, and high-vacuum systems.
• Hands-on experience building, deploying, troubleshooting, and maintaining diagnostics on plasma research devices.
• Familiarity with fusion diagnostics and associated radiation safety protocols.
• Experience with data analysis using Python (preferred) or similar tools.
• Working knowledge of simulation tools for modeling plasma behavior.
• Experience with project collaboration and document management platforms.
• 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.

At 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.
