Structural Analysis Engineer

Oak Ridge. TN

Location: Oak Ridge, TN  

Schedule: Full-Time 

 

FUNCTION 

The Structural Analysis Engineer serves as the responsible licensed engineer for structural qualification and analysis activities across Standard Nuclear’s facilities, products, and engineered systems. 

This role is accountable for performing and sealing structural analyses supporting thermomechanical, dynamic, seismic, and impact evaluations in nuclear and aerospace applications. The engineer will develop and defend analysis methodologies, ensure code compliance, and provide technical sign-off for critical design decisions. 

The role requires strong proficiency in ANSYS Mechanical (or equivalent FEA platforms), deep understanding of solid mechanics, and the ability to translate complex simulation results into defensible engineering conclusions. 

 

RESPONSIBILITIES 

Structural & Thermomechanical Analysis 

  • Develop and execute finite element models using ANSYS Mechanical or equivalent tools. 
  • Perform static, dynamic, nonlinear, thermal, and modal analyses as required. 
  • Conduct coupled thermomechanical evaluations for high-temperature and heat-generating systems. 
  • Evaluate structural performance under operational and extreme loading conditions. 
  • Perform local stress analysis where beam models are insufficient. 

Seismic & Dynamic Qualification 

  • Perform seismic qualification analyses, including response spectrum and time-history evaluations. 
  • Conduct dynamic and impact modeling for transport-critical systems. 
  • Evaluate vibration, shock, and transient loading conditions. 
  • Ensure structural systems meet applicable code and regulatory requirements. 

Responsible Engineering & Sign-Off 

  • Serve as the licensed Professional Engineer responsible for sealing analysis packages, as required. 
  • Develop defensible assumptions, boundary conditions, and load cases. 
  • Ensure analyses are performed in accordance with applicable codes and standards (e.g., ASME Section III where applicable). 
  • Document methodologies, results, and engineering conclusions clearly and thoroughly. 
  • Support internal and external technical reviews. 

Cross-Functional Engineering Support 

  • Collaborate with mechanical, systems, manufacturing, and facilities engineers to define modeling inputs and constraints. 
  • Support design reviews, facility modifications, and equipment installations with analysis-driven insights. 
  • Participate in engineering investigations and failure analyses. 
  • Mentor junior engineers or analysts, as needed. 

 

PREFERRED QUALIFICATIONS 

  • Bachelor’s or Master’s degree in Mechanical Engineering, Structural Engineering, Engineering Mechanics, or related discipline. 
  • Active Professional Engineer (PE) license. 
  • 5+ years of structural analysis experience in industrial, nuclear, aerospace, or heavy mechanical systems. 
  • Demonstrated experience performing nonlinear FEA using ANSYS Mechanical or equivalent. 
  • Experience with modal, dynamic, and seismic analysis methods. 
  • Strong understanding of solid mechanics, material behavior, and structural dynamics. 
  • Ability to independently develop, defend, and seal engineering analyses. 
  • Experience preparing formal engineering calculation packages and technical reports. 

 

BENEFITS 

  • Health, Dental & Vision Insurance 
  • Health Savings Account 
  • Disability and Life Insurance 
  • 401(k) Plan 
  • Paid Time Off and Holidays

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
