* Job Description:

** The FEA / Simulation Engineer develops and applies advanced engineering models to predict the structural performance, durability, and failure behavior of polymer, fiber-reinforced polymer, carbon composite, and metallic components.

The role converts customer and internal design requirements into defensible simulation plans, performs linear and nonlinear finite element analyses, correlates models with physical testing, and translates results into practical design and manufacturing recommendations.

The engineer will help expand simulation capability for anisotropic, short-fiber, discontinuous-fiber, including workflows that connect material behavior, fiber orientation, process history, and structural response.

The position also supports the evaluation and adoption of advanced engineering software, automation, artificial intelligence, machine learning, generative design, and related digital tools that improve analysis quality, speed, repeatability, and engineering decision-making.

Experience with injection molding simulation software such as Moldex3D or Autodesk Moldflow, or practical injection molding experience, is beneficial but not required. The successful candidate must be willing and able to learn Moldex3D, Moldflow, and other advanced simulation and AI-enabled engineering systems as business and technical needs evolve.  MAIN/KEY RESPONSIBILITIES AND

ACCOUNTABILITIES :

Finite Element Analysis & Structural Simulation
• Plan, build, execute, and document finite element analyses for polymer, composite, and metallic components using customer-derived and internally defined load cases.
• Create linear and nonlinear static models, including material nonlinearity, geometric nonlinearity, large deformation, contact, friction, preload, and boundary-condition sensitivity as appropriate.
• Assess stress, strain, deformation, stiffness, stability, fatigue, life, and likely failure locations using analysis methods appropriate to the material, geometry, and application.
• Apply composite laminate theory, anisotropic material definitions, ply-level results, and suitable composite failure criteria to evaluate laminated structures.
• Develop methods for short-fiber and discontinuous-fiber structures, including mapped orientation and spatially varying material properties when supported by available process data.
• Evaluate mesh quality, convergence, assumptions, simplifications, and uncertainty; perform sensitivity studies and clearly identify model limitations.
• Optimize designs for weight, strength, life, manufacturability, dimensional performance, and other functional requirements.

Model Validation, Testing & Failure Analysis
• Define test requirements needed to establish loads, material inputs, boundary conditions, and validation data for engineering models.
• Partner with laboratory, design, manufacturing, and external testing resources to correlate analytical predictions with physical test results.
• Perform or support failure analysis to identify stress concentrations, load-path issues, local instabilities, contact problems, and material or design-related failure modes.
• Refine models based on test evidence and document correlation quality, residual uncertainty, and recommended next steps.
• Develop reusable modeling practices, material cards, validation approaches, and engineering standards that improve confidence and consistency across projects.

Design Support & Technical Recommendations
• Collaborate with design engineers to evaluate concepts, compare alternatives, and recommend geometry, material,…
