About the job
Inertia Enterprises is at the forefront of innovative technology, developing the first fusion energy power plant in the world. Located in a state-of-the-art 48,000 sq.ft. facility in Livermore, CA, we are looking for a Mechanical Engineer specializing in Thermal and Structural Analysis. This pivotal role involves spearheading the analysis and supporting the mechanical design of essential components and structures for our integrated power plant.
In this position, you will engage in designing and analyzing components and structures that must endure the most extreme engineering conditions, intense x-ray and neutron flux, high temperatures, severe thermal gradients, high pressures, and powerful laser beams, among others. Your expertise will be crucial in analyzing our fusion engine structures, including the first wall and breeding blanket structures, while also supporting the design and fabrication of high-power laser delivery components and fusion target materials.
Primary Responsibilities
Lead the mechanical design and 3D modeling of key fusion engine systems, structures, and components, including the chamber, first wall, blanket, vacuum chamber, and piping.
Direct thermal-structural analysis of critical components such as the engine first wall and tritium breeding blanket under both steady-state and transient conditions. Focus on optimizing structures for effective heat removal, thermal longevity, and manufacturability.
Assess the impact of cyclic heat flux, creep loading, and fatigue loading on chamber components using relevant models and standards to predict the operational lifespan of the fusion core. Account for irradiation effects in thermal mechanical analyses.
Perform thermal and structural analyses and parametric studies to validate and refine material selections and mechanical designs, documenting insights and results in technical reports.
Actively engage in design reviews and risk assessment, identifying technical gaps, tracking action items, and integrating feedback from stakeholders into the design process.
Conduct finite element analysis and thermal-mechanical analysis on additional key structures and components, including stress analysis of helium-cooled high-power laser optics and thermal stability of fusion target sub-structures.
