Thea Energy is a fusion energy company leveraging stellarator physics breakthroughs to commercialize fusion power. The company uses computer-controlled arrays of planar coils to simplify stellarator design, replacing complex modular magnets in traditional architectures. This role is a Senior Integration Engineer focused on systems engineering for nuclear process integration.
You will work on an interdisciplinary team integrating first-of-a-kind fusion technologies while developing scalable processes and procedures. Key responsibilities include:
• Develop and maintain process flow diagrams (PFDs) and process architectures for nuclear and supporting plant systems
• Develop system-level mass and energy balances and define major process streams and operating conditions
• Establish system boundaries and identify, document, and manage interfaces between systems
• Translate plant-level functions into system and subsystem requirements
• Define process requirements for normal, startup, shutdown, maintenance, and abnormal operating modes
• Integrate process systems including fuel-cycle/tritium processing, vacuum, cooling, heat transport, utilities, and other supporting systems
• Work with mechanical, electrical, controls, nuclear, safety, and other engineering disciplines to resolve cross-functional technical issues
• Support development of P&IDs, equipment specifications, process requirements, and interface control documentation
• Identify process integration risks, dependencies, and opportunities for simplification
• Participate in design reviews, FMEA/HAZOP activities, safety analyses, and technical risk assessments
• Support control philosophies and operating strategies with controls and software engineers
• Support system integration, commissioning, and operational readiness activities
• Maintain configuration and technical consistency of process architecture as design evolves
The ideal candidate is self-motivated, organized, and collaborative with a proven track record leading systems engineering. Excellent communication skills, passion for innovation, and ability to move quickly in a dynamic, first-of-a-kind development environment are essential. You must demonstrate high autonomy and the ability to solve complex problems.
REQUIREMENTS:
• Bachelor's or advanced degree in Nuclear Engineering, Chemical Engineering, Mechanical Engineering, or related discipline
• 8+ years of relevant experience in nuclear, fusion, chemical/process, or other highly regulated process systems
• Demonstrated experience developing PFDs, P&IDs, process architectures, and mass/energy balances
• Experience defining system interfaces and working across multiple engineering disciplines
• Experience with tritium processing, nuclear fuel-cycle systems, isotope processing, or fusion fuel-cycle systems (strongly preferred)
• Experience with vacuum, gas handling, cryogenic, or high-purity process systems (a plus)
• Familiarity with nuclear safety, configuration management, and formal engineering processes
• Ability to work effectively in a dynamic, first-of-a-kind development environment
Note: It is not necessary to meet all skillsets outlined above; candidates are encouraged to apply and explain why they would be a great fit.
