Structural/Mechanical Analysis Engineer

Omega Technical Services is hiring a Structural/Mechanical Analysis Engineer to support elevated-temperature nuclear component design evaluations under ASME BPVC Section III, Division 5. The role performs code-compliance analysis, develops finite element models, and supports independently reviewable calculation packages for nuclear component structural integrity.

Responsibilities:

• Provides structural and mechanical analysis support for elevated-temperature nuclear component design evaluations in accordance with ASME BPVC Section III, Division 5
• Performs code-compliance analysis supporting the structural integrity of elevated-temperature nuclear components, including load-controlled stress evaluations, stress classification and linearization, and finite element model development
• Supports the preparation of code-compliant, independently reviewable calculation packages and contributes to the technical rigor underpinning the design and safety basis of next-generation nuclear components

Requirements:

• Must possess a Bachelor of Science degree in mechanical engineering or a directly related field, with a minimum of 8 years of relevant experience; or a Master of Science degree in mechanical engineering or a directly related field, with a minimum of 6 years of relevant experience
• The qualifying degree must be from an ABET-accredited program
• Candidate must be a U.S. Citizen
• Candidate must be able to obtain and maintain a DOE Security Clearance
• Working knowledge of ASME BPVC Section III, Division 5 (or demonstrated transferable experience in Section III Division 1 or Section VIII with elevated-temperature exposure)
• FEA experience (ANSYS, Abaqus, or equivalent), including 3D model development, mesh convergence, and boundary condition documentation
• Hands-on experience with creep-fatigue damage evaluation, including time-dependent creep and fatigue interaction, usage factors, and hold-time effects, per Subsection HBB / Mandatory Appendix HBB-I
• Experience with strain limits, ratcheting, and incremental collapse assessment
• Experience with elevated-temperature buckling, including thermal and creep buckling
• Demonstrated ability to produce code-compliant, independently reviewable calculation packages
• Experience with weld strength reduction factors, dissimilar metal weld assessment, or bolted joint fatigue/relaxation analysis under Division 5
• Familiarity with Section II, Part D material allowables
• Prior DOE national laboratory or nuclear component supplier experience
• Possession of an active DOE/DoD clearance within the past two (2) years is preferred
• Previous DOE/NNSA work experience
• Working knowledge of ASME BPVC Section III, Division 5 nuclear component design requirements
• FEA experience, including 3D model development, mesh convergence, and boundary condition documentation
• Ability to apply general code rules to specific analysis problems to produce technically sound, defensible results
• Ability to combine analytical results to form conclusions supporting code-compliance determinations
• Ability to listen to and understand technical information and ideas presented through discussion with technical leads and stakeholders
• Ability to communicate analysis results and technical findings clearly, in writing and verbally
