Overview
Inertia Enterprises is developing the technologies to build the world’s first fusion energy power plant. At our 48,000 sq.ft. facility in Livermore, CA, we are seeking a Senior Mechanical Engineer - Fusion Engine Design and Analysis to lead analysis and support the mechanical design of critical components and structures of Inertia’s integrated fusion power plant.
This role will lead the design and analysis of components and structures, including the first wall and breeding blanket structures, that must survive the harshest conditions known to engineering— intense x-ray and neutron flux, high temperatures, extreme thermal gradients, corrosion, among others.
What You'll Get to Do
Develop the mechanical design and 3D modeling of the fusion engine key systems, structures and components: chamber, first wall, blanket, vacuum chamber, piping.
Lead mechanical design and thermal-structural analysis of key components such as the engine first wall and tritium breeding blanket, in steady-state and transient conditions. Optimize structures for heat removal, thermo-mechanical longevity, manufacturability.
Evaluate the effects of cyclic heat flux, creep loading, fatigue loading on chamber components using relevant models, codes and standards to predict the operational lifespan of the fusion core. Account for effects of irradiation (displacement per atom and helium) in thermal mechanical analyses.
Conducts thermal and structural analyses and parametric studies to validate and optimize materials choices and mechanical designs, capturing insights and results in technical documentation and reports
Actively participates in design reviews and risk matrix development, helping to identify technical gaps, track open action items, and incorporate feedback from various stakeholders into the design.
Support and mentor other mechanical engineers, designers, and analysts working on other company priorities such as high power laser design, fusion target design. .
What You Bring to Inertia
Bachelor’s or advanced degree in Mechanical, Aerospace, Materials, Nuclear, Structural or a related engineering discipline.
7+ years of experience in mechanical design and analysis of structural materials in chemical, power generation, oil & gas, nuclear, defense, or aerospace industries.
Expert-level skills in mechanical design and computer-aided design (CAD)
Expertise in finite element analysis using codes such as ANSYS or Abaqus applied for stress and thermal analysis
Knowledge of FEA and other spatial/time discretization techniques for partial differential equation (PDE) systems.
Familiarity with application of numerical material models to metallic systems, structures and components
Experience with alloys and metals, high temperatures, high heat fluxes, and/or irradiation effects on materials
Bonus Points
Experience with power plant design
Experience in/knowledge of Computational Materials Science or Mechanics preferred
Experience developing scientific codes and softwares using C++, Fortran, python or similar programming language
Experience with fusion or nuclear technologies
Working knowledge of ASME Boiler and Pressure Vessel Codes, with specific interest in high-temperature service rules.
