Prinicpal Engineer, Structural Integrity

Los Angeles$190k–$250kfulltimemidAdded 3 days ago

About this role

Lead the development and ownership of structural integrity methods and frameworks for Antares' high-temperature nuclear reactor components. This Principal Engineer role focuses on establishing material modeling, design qualification, and life assessment capabilities that bridge material science, regulatory codes, and operational safety for advanced microreactor systems.

What you'll do

  • Build and own the structural integrity framework covering design, qualification, operation, inspection, and fitness-for-service assessments
  • Serve as technical authority for structural integrity and materials modeling across the organization
  • Lead application of ASME Section III Division 5 and UK R5/R6 methods for high-temperature component life assessment
  • Translate material test data into qualified models, design properties, allowables, and acceptance criteria for structural analysis
  • Develop and qualify methods for creep, fatigue, creep-fatigue, thermal aging, irradiation effects, and fracture analysis
  • Guide materials testing strategy, defect evaluation, aging management, and remaining-life assessment programs

What they're looking for

  • Structural integrity and high-temperature materials behavior
  • ASME Section III Division 5 and UK R5/R6 code requirements
  • Creep, fatigue, creep-fatigue, and fracture mechanics analysis
  • Finite-element and constitutive materials modeling
  • Verification, validation, and uncertainty quantification of engineering methods
  • Material testing data reduction and design allowables development
  • Irradiation effects on metallic materials (preferred)
  • Leadership and cross-functional collaboration
