Multiphysics Modeling Engineer

About Type One Energy

Type One Energy Group is mission-driven to provide sustainable, affordable fusion power to the world. Established in 2019 and venture-backed in 2023, the company is led by a team of globally recognized fusion scientists with a strong track record of building state-of-the-art stellarator fusion machines, together with veteran business leaders experienced in scaling companies and commercializing energy technologies.

Your Role in the Mission

Type One Energy is seeking a highly experienced and technically strong Multiphysics Modeling Engineer to drive the development, integration, and application of advanced multiphysics simulation capabilities for fusion energy systems. This role is responsible for establishing and executing the company’s strategy for MOOSE-based simulation across plasma-facing components, structural systems, blankets, and tritium-relevant subsystems. The role will play a critical part in enabling high-fidelity, tightly coupled simulations to inform the design of the Infinity Two stellarator power plant and future commercial systems.

What You’ll Need

• PhD or equivalent experience in Nuclear Engineering, Mechanical Engineering, Physics, Materials Science, Computer Science, or a related field.
• Proven track record in multiphysics simulation and computational modeling, ideally in fusion, advanced fission, or high-performance energy systems.
• Deep experience with the MOOSE framework and its ecosystem.
• Strong understanding of coupled physics relevant to fusion systems, including: Heat transfer and thermal hydraulics, Structural mechanics and material behavior, Radiation effects and materials degradation, Tritium/hydrogen transport, and Electromagnetic effects (desirable).
• Familiarity with complementary tools such as OpenMC, MCNP, ANSYS, COMSOL, OpenFOAM, or plasma simulation codes.
• Experience developing or extending scientific software in C++ and/or Python.
• Demonstrated experience leading technical programs and managing complex, multidisciplinary modeling efforts.
• Experience with verification and validation methodologies and uncertainty quantification.
• Familiarity with HPC environments and parallel computing.
• Experience integrating multiple simulation tools and managing complex workflows.
• Strong analytical, problem-solving, and systems-thinking skills.
• Excellent communication skills, with the ability to translate advanced simulation results into engineering insight.
