Company: Mitsubishi Performance Polymers Division 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, tolerance, interface, and load-path improvements. • Support conversion of metallic designs to polymer or composite solutions by assessing performance tradeoffs and identifying design changes needed for material substitution. • Use simulation early in development to reduce technical risk, guide prototypes, focus physical testing, and accelerate design iterations. • Provide clear, actionable recommendations rather than analysis results alone, connecting technical findings to customer requirements, manufacturability, cost, schedule, and commercialization risk. • Participate in design reviews, project reviews, customer discussions, and technical problem-solving sessions. Manufacturing Process Simulation & Injection Molding Knowledge • Where qualified, apply process simulation or manufacturing knowledge to improve understanding of how molding conditions, fiber orientation, weld lines, shrinkage, warpage, residual stress, and other process effects may influence structural performance. • Experience with Moldex3D, Autodesk Moldflow, or injection molding is beneficial but is not a minimum requirement for the position. • Learn and become proficient with Moldex3D, Moldflow, or comparable process-simulation platforms when required, including workflows that transfer process results into structural analysis. • Work with manufacturing and materials teams to understand actual process conditions and ensure simulation assumptions appropriately reflect how components are produced. Advanced Software, AI & Generative Engineering • Evaluate and adopt new engineering software and digital workflows that expand simulation capability or improve analysis speed, quality, traceability, and repeatability. • Participate in the development of connected workflows between CAD, process simulation, material models, structural analysis, testing data, and engineering knowledge systems. • Validate AI-generated or automated outputs using sound engineering judgment, documented checks, and applicable company requirements before results are used for technical decisions. • Maintain a strong learning mindset and develop proficiency in unfamiliar advanced software systems as technology and business needs evolve. Technical Documentation, Collaboration & Project Execution • Prepare analysis plans, calculation packages, technical reports, design recommendations, and presentations that clearly communicate methods, assumptions, results, risks, and conclusions. • Present complex technical findings to engineering, manufacturing, commercial, leadership, customer, and supplier audiences at an appropriate level of detail. • Manage assigned analysis activities to agreed scope, schedule, and quality expectations while communicating risks and resource needs early. • Work effectively across global and cross-functional teams and protect customer, company, and third-party confidential information and intellectual property. • Contribute to capability roadmaps, software evaluations, licensing recommendations, training, templates, methods development, and continuous improvement of the simulation function. Safety, Quality & Compliance • Incorporate safety, quality, and applicable regulatory considerations into modeling, design recommendations, test planning, and technical reviews. • Follow company procedures for engineering documentation, data management, software use, model review, and technical approval. • Support safe laboratory and test activities and identify analysis-related risks that could affect personnel, equipment, product performance, or customer use. 5.0 SPECIAL FEATURES: This role may support multiple sites, global teams, customer programs, laboratories, and manufacturing operations. Limited travel may be required based on project needs. 6.0 KNOWLEDGE/ EXPERIENCE/SKILLS: 7.0 EDUCATION FEA Expertise: Strong working knowledge of finite element methods, model idealization, meshing, boundary conditions, loads, contacts, material models, convergence, verification, and interpretation of results. Materials & Mechanics: Sound understanding of solid mechanics, strength of materials, failure theories, and the mechanical behavior of polymers, composites, and metals. Knowledge of laminate theory and composite failure criteria is required for composite-focused work. Nonlinear Analysis: Ability to solve and troubleshoot nonlinear problems involving contact, friction, large deformation, nonlinear geometry, and nonlinear material behavior. Validation & Engineering Judgment: Ability to define test needs, correlate models to data, recognize uncertainty, challenge assumptions, and distinguish numerical output from defensible engineering conclusions. Digital Learning Agility: Demonstrated ability and willingness to learn advanced engineering systems, including process simulation, optimization, AI-assisted, machine-learning, generative design, and automation tools. Communication & Collaboration: Ability to communicate technical results clearly in written reports and presentations and to work effectively with design, materials, testing, manufacturing, commercial, supplier, and customer teams.
