Company

hirify.global is a startup building the world’s first mass-produced, portable nuclear microreactors to provide critical power for hospitals, data centers, and military bases.

What you will do

• Develop and own static, dynamic, and transient loads for reactor systems, support structures, and transport configurations.
• Perform structural dynamics analyses, including modal, random vibration, shock, sine vibration, and fatigue assessments.
• Implement explicit dynamics simulations to model nonlinear reactor response under transient seismic and transportation events.
• Conduct finite element analyses (FEA) using tools such as ANSYS, Abaqus, or similar software.
• Collaborate with design engineers to influence hardware architecture, material selection, and joint design.
• Support test planning and correlation, including shaker tests and modal surveys.

Requirements

• Bachelor’s degree in Mechanical, Aerospace, or Structural Engineering.
• 5+ years of experience in loads, dynamics, or structural analysis for complex mechanical systems.
• Proficiency with industry-standard FEA tools (e.g., ANSYS, Abaqus, Nastran).
• Strong fundamentals in structural mechanics, dynamics, and vibration.
• Must work 100% onsite in El Segundo, CA.
• Must be able to serve in compliance with U.S. export controls.

Nice to have

• Experience in aerospace, launch, defense, or nuclear hardware environments.
