About this Senior Integration Engineer - Nuclear Process role at Thea Energy
We are looking for a Senior Integration Engineer - Nuclear Process to help define and integrate the process architecture of a first-of-a-kind fusion energy system. This role sits at the intersection of nuclear engineering, process engineering, and systems integration. You will develop process flows and system architecture connecting major plant systems, define system boundaries and interfaces, and work with engineering teams to translate the plant concept into an integrated, buildable system. The ideal candidate has strong process engineering fundamentals combined with nuclear systems experience, preferably in tritium processing and fusion fuel-cycle systems.
We are looking for a systems thinker who naturally asks how the process works as a complete system and what every neighboring system needs from it. You are comfortable working from incomplete information, identifying gaps, and bringing engineers from different disciplines together to resolve them.
Key Responsibility Areas:
• 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 the design evolves.
