Senior Integration Engineer - Nuclear Process
About The Position
Thea Energy is seeking 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 is at the intersection of nuclear engineering, process engineering, and systems integration. The successful candidate will develop process flows and system architecture connecting major plant systems, define system boundaries and interfaces, and collaborate with engineering teams to translate the plant concept into an integrated, buildable system. The ideal candidate possesses strong process engineering fundamentals combined with nuclear systems experience, particularly in tritium processing and fusion fuel-cycle systems. This role requires a systems thinker who understands how processes function as a complete system and the needs of neighboring systems. The candidate should be comfortable working with incomplete information, identifying gaps, and facilitating collaboration among engineers from different disciplines to resolve issues.
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.
- Familiarity with nuclear safety, configuration management, and formal engineering processes.
- Ability to work effectively in a dynamic, first-of-a-kind development environment.
Nice To Haves
- 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 is a plus.
Responsibilities
- 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 the design evolves.
Benefits
- Comprehensive health benefits (e.g. medical/dental/vision)
- Employee equity stock options
- 20 days PTO
