CAE Engineer

Description Overview
- Senior CAE Application Engineer Rafinex is looking for an experienced senior CAE Application Engineer to support a variety of design projects across prototypes, pre-series and production vehicles/components in the defence and security industries (e.g. space, unmanned systems, aerospace applications). The role is primarily focused on CAE/FEA for structural mechanics and advanced topology optimization; covering a full workflow from problem definition through result evaluation. Integration and collaboration with further colleagues and tools on multi-physics codes and analysis is required. The algorithms and software to be used range from Rafinex internal proven tools through to cutting-edge developmental and research codes that may need verification and validation support. A sound foundational understanding of the underlying FEA theory and numerical implementation aspects is required. This role is physically based in Luxembourg, offering a flexible remote environment. The role is full time and should be long-term to accompany the projects from design phase to manufacturing, trial and testing deployments. Experience in working on sensitive and/or classified materials is an advantage, though not a strict requirement. Starting as soon as possible. Roles & Responsibilities
• Use Rafinex’ simulation software for i) FEA for structural mechanics applications, ii) Stochastic topology optimization studies and iii), Algorithm performance profiling and computational scalability
• Identify structural load scenarios, and compare load cases at assembly and component level.
• Combine simulation results and produce engineering reports capable of providing relevant technical insights and recommendations to design and simulation engineers.
• Create and interpret free body diagrams to define load paths and support accurate simulation setup, with appropriate approaches for connecting different components of large assemblies.
• Creating and modifying solid and surface CAD models; preparing models for analysis; resurfacing results from topology optimization.
• Pre-processing operations including geometry preparation / defeaturing / meshing and automation.
• Post-processing operations using Rafinex tools or open-source software (Paraview); scripting and automation.
• Contribute to product roadmap, identifying future capability requirements / comparison with competitors.
• Assist in validation and verification of analysis and optimization methods.
• Collaborate and integrate structural FEA results and methodologies with other multi-physics tools and software from partners and research centers.
• Take global project ownership from administrative conception to final delivery and post-delivery reporting, including delegation and directing sub-teams / suppliers. Candidates with a strong background in a distinct subset of the above Responsibilities will be considered for a standalone Role. About You
