• Collaborate in the development and implementation, and utilize innovative multidisciplinary approaches and technology to lead advanced level system modeling efforts to predict complex diagnostic performance that guides the development of novel plasma diagnostic requirements.
• Establish project objectives and strategy, and influence technical direction by applying high-level technical concepts and techniques to drive successful outcomes for deliverables.
• Provide advanced level technical guidance and mentorship to technical staff across the target diagnostic engineering and science organizations, fostering their technical development and supporting their growth within the team.

• Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
• Bachelor's degree in physics, applied physics, nuclear engineering, electrical engineering, or a relevant technical field, or the equivalent combination of education and related experience.
• Comprehensive level knowledge of and demonstrated practical experience with the application and development of building, testing, and deploying moderately complex diagnostic instrument hardware systems.
• Demonstrated familiarity and proficiency in technical troubleshooting, test plan development, experimental testing, and data analysis.
• Comprehensive level knowledge of, and experience developing and utilizing programming (esp. Python), particularly for data/image/signal processing analysis and hardware interface control.
• Proficient with electrical diagnostic hardware including oscilloscopes, imaging sensors, and other data acquisition systems.
• Broad understanding and experience with one or more of the following diagnostics: x-ray diagnostics, nuclear diagnostics, optical diagnostics, laser systems, or high-speed diagnostics (steak cameras, photodetectors, gated/framing cameras)
• Broad experience with and application of hardware control and software automation using Python.
• Comprehensive level problem-solving skills and a demonstrated hands-on approach to engineering challenges.
• Proficient written and verbal technical communication skills, including the ability to prepare technical reports, deliver presentations, and explain technical information.
