FEA Analysis Engineer 

 

Location: Oak Ridge, TN  

Schedule: Full-Time 

 

FUNCTION 

The FEA Analysis Engineer will support Standard Nuclear’s engineering efforts by performing finite element modeling (FEM/FEA) to evaluate the behavior, reliability, and safety of mechanical and structural systems across our facilities. This role focuses on advanced simulation and structural mechanics—analyzing equipment, components, and facility structures under operational and extreme loading conditions. 

The engineer will work closely with mechanical, systems, and facilities engineering teams to develop models, run simulations, and translate results into practical engineering guidance. Strong proficiency in ANSYS or similar tools is required. 

 

RESPONSIBILITIES 

Finite Element Modeling & Simulation 

• Develop and run finite element models using ANSYS or equivalent FEA platforms. 

• Perform static, dynamic, nonlinear, thermal, and modal analyses as required. 

• Evaluate system performance under mechanical loads, thermal loads, vibration, and seismic events. 

• Conduct critical scenario modeling (e.g., seismic-induced structural behavior related to nuclear safety limits). 

Engineering Evaluation & Reporting 

• Interpret simulation results and provide engineering recommendations to design and operations teams. 

• Prepare formal analysis reports, calculations, and engineering documentation. 

• Work with cross-functional teams to define modeling assumptions, constraints, and validation requirements. 

Cross-Functional Support 

• Support equipment installation, facility modifications, and design reviews by providing simulation-driven insights. 

• Collaborate with mechanical, process, and facilities engineers to validate model inputs and boundary conditions. 

• Assist in engineering investigations, failure analyses, and assessment of system vulnerabilities. 

 

PREFERRED QUALIFICATIONS 

• Bachelor’s or Master’s degree in Mechanical Engineering, Engineering Mechanics, Structural Mechanics, or related field. 

• 3–5+ years of experience performing advanced FEA in a professional engineering environment. 

• Proficiency with ANSYS, Abaqus, COMSOL, Bison, or similar FEA packages. 

• Strong understanding of solid mechanics, structural dynamics, and materials behavior. 

• Experience modeling systems subject to seismic or dynamic loads preferred. 

• Ability to interpret engineering drawings and mechanical system details. 

• Strong communication skills and experience writing technical reports. 
• Comfortable working in a fast-paced, multidisciplinary engineering environment. 

 

BENEFITS 

• Health, Dental & Vision Insurance 

• Health Savings Account 

• Disability and Life Insurance 

• 401(k) Plan 

• Paid Time Off and Holidays
