Overview

Radiant Industries seeks a Staff Loads & Dynamics Engineer to lead structural loads vibration and dynamic analyses for the Kaleidos portable nuclear microreactor. The engineer will ensure structural integrity across manufacturing transportation deployment and operational phases. This role demands ownership of static dynamic and transient load development and execution of advanced simulations. Collaboration with multidisciplinary teams is essential. The ideal candidate thrives in fast‑paced ambiguous environments and drives design decisions through rigorous analysis.

What You'll Do11

  • 1Develop and own static dynamic and transient loads for reactor systems support structures and transport configurations
  • 2Perform structural dynamics analyses including modal random vibration shock sine vibration and fatigue assessments
  • 3Implement explicit dynamics simulations to model nonlinear reactor response under seismic and transportation events
  • 4Define transportation and handling environments analyzing shock and vibration from road rail air or sea
  • 5Generate load cases and environments to support structural sizing design margins and verification plans
  • 6Conduct finite element analyses using ANSYS Abaqus or similar tools
  • 7Collaborate with design engineers to influence hardware architecture material selection and joint design
  • 8Support test planning and correlation including shaker tests modal surveys and structural verification testing
  • 9Maintain analysis documentation reports and requirements for internal reviews and regulatory interfaces
  • 10Contribute to failure investigations root cause analyses and design improvements
  • 11Establish best practices for loads dynamics and structural verification within a growing engineering organization

Requirements13

  • 1Bachelor’s degree in Mechanical Engineering Aerospace Structural or related field
  • 25+ years of experience in loads dynamics or structural analysis for complex mechanical systems
  • 3Strong fundamentals in structural mechanics dynamics and vibration
  • 4Proficiency with industry standard FEA tools such as ANSYS Abaqus or Nastran
  • 5Familiarity with design allowables safety factors and margin of safety methodologies
  • 6Ability to work cross functional and communicate analysis results clearly to technical and non technical stakeholders
  • 7Experience in aerospace launch defense nuclear or heavy industrial hardware environments
  • 8Dynamics modeling software experience LD Dyna Abaqus explicit or other
  • 9Background in shock and vibration testing and test article correlation
  • 10Knowledge of fatigue fracture mechanics and bolted joint analysis
  • 11Experience defining or interpreting environmental specifications and requirements
  • 12Master’s degree or PhD in a relevant engineering discipline
  • 13Familiarity with nuclear spaceflight or safety critical system requirements
