Job summary

Radiant seeks a Staff Loads & Dynamics Engineer in El Segundo, CA to own static, dynamic, and transient loads for reactor systems and transport configurations. You will perform modal, random vibration, shock, and fatigue analyses, and execute explicit dynamics simulations to model nonlinear reactor responses during seismic and transport events.

You will collaborate with design, thermal, and test teams, drive FE analyses with ANSYS/Abaqus/Nastran, and develop verification plans and documentation

Qualifications

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or a related field.
• 5+ years of experience in loads, dynamics, or structural analysis for complex mechanical systems.
• Strong fundamentals in structural mechanics, dynamics, and vibration.
• Experience with finite element modeling and analysis of metallic and composite structures.
• Proficiency with industry-standard FEA tools (e.g., ANSYS, Abaqus, Nastran).
• Familiarity withdesign allowables, safety factors, and margin-of-safety methodologies.
• Ability to work cross-functionally and communicate analysis results clearly to both technical and non-technical stakeholders.

Responsibilities

• 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 event cases.
• Define and analyze transportation and handling environments, including shock and vibration from road, rail, air, or sea transport.
• Generate load cases and environments to support structural sizing, design margins, and verification plans.
• Conduct finite element analyses (FEA) using tools such as ANSYS, Abaqus, or similar tools.
• Collaborate with design engineers to influence hardware architecture, material selection, and joint design.
• Support test planning and correlation, including shaker tests, modal surveys, and structural verification testing.
• Develop and maintain analysis documentation, reports, and requirements for internal reviews and regulatory interfaces.
• Contribute to failure investigations, root cause analyses, and design improvements
• Help establish best practices for loads, dynamics, and structural verification within a growing engineering organization.
