What You'll Be Doing:You will be at the forefront of designing the world's first continuous fusion fuel cycle - an opportunity to redefine the future of clean energy for the modern world. This role operates at the intersection of process design, system integration, and program strategy, owning the performance, scalability, and operability of the fuel cycle across its full lifecycle. You'll work collaboratively with Engineering, Science, R&D, Operations, and Leadership, serving as a technical authority focused on setting design direction, resolving first-of-a-kind engineering challenges, and delivering critical systems for an integrated, closed-loop fuel cycle. You will report to the Fuel Cycle Manager and work onsite at our Everett, WA office.
You Will:
- Own delivery of major fuel cycle systems from concept through integration, including process design, procurement, installation, and commissioning
- Define plant-level fuel cycle philosophy and tradeoffs, including operational approach, throughput, energy usage, holdup inventories, and safety across fuel cycle systems
- Utilize first-principles analysis, modeling, and rigorous simulation tools to evaluate steady-state, dynamic, and fault scenarios to ensure design operability
- Set technical direction for and guide detailed design of process equipment (e.g., columns, reactors, membranes, heaters, exchangers, pumps, and piping) across ambient, high-temp, cryogenic, and vacuum conditions
- Develop and maintain core engineering design deliverables (PFDs, P&IDs, H&MBs, HAZOPs, and sizing calculations), ensuring technical rigor and consistency across the program
- Drive cross-functional alignment across Science, R&D, EHS, Fuel Cycle Operations, and Plant Engineering to deliver a cohesive and scalable fuel cycle
- Lead high-level design reviews as the decision authority, resolving complex technical issues and ensuring alignment with program goals
- Ensure technical rigor and alignment of detailed engineering work across team process designs (e.g., columns, reactors, membranes, cryogenic and vacuum systems)
- Mentor and develop senior engineers, establish engineering best practices, and shape team capability and technical standards
- Represent Helion as a technical authority in external engagements, communicating fuel cycle architecture, design decisions, and program direction through industry forums, conferences, and publications
Required Skills:
- Bachelor's or Master's degree in Chemical Engineering, Mechanical Engineering, Nuclear Engineering, or related field; advanced degree preferred
- 12+ years of experience in chemical process design, translating process concepts into first-of-a-kind hardware
- Deep technical expertise in transport phenomena (mass, heat, and momentum), thermodynamics, and reaction engineering applied to complex process systems
- Decomposition of complex problems into fundamental physical principles, process objectives, and operational constraints to develop solutions grounded in first-principles reasoning
- Demonstrated ownership of large-scale integrated systems, defining requirements and driving clarity in ambiguous problem spaces
- Demonstrated accountability leading multi-disciplinary efforts and making system-level decisions with significant program impact
- Accountable as the technical authority for a technology domain, with expertise in relevant-to-fusion fuel cycle engineering, such as isotope separation, impurity separation, tritium handling, cryogenic systems, or vacuum systems
