Senior Integration Engineer - Nuclear Process
Summary
Senior process/nuclear engineer at Thea Energy (a fusion startup) to define and integrate the process architecture of a first-of-a-kind fusion plant: developing PFDs, mass/energy balances, and system boundaries and interfaces, and aligning tritium/fuel-cycle, vacuum, cooling, and utility systems across engineering disciplines.
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.
Ideal Experience & Skillsets:
- 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 is 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.
Company Benefits:
- Salary range $150,000-$180,000
- Comprehensive health benefits (e.g. medical/dental/vision)
- Employee equity stock options
- 20 days PTO
