CAE Simulation Engineer (LS-DYNA)

Role: CAE Simulation Engineer (LS-DYNA)

Location: Ahmedabad, Gujarat, India (On-site)

Employment type: Full-time

Industry: Space Technology

About Catalyx Space:

We’re building AWS for space—providing in-space experiments and tech demos across LEO, deep space, and lunar orbit. Our offerings include unmanned labs, testbeds for rideshare and dedicated missions, and re-entry capsules for payload return. We simplify access with end-to-end solutions, no minimum mass limits, zero integration fees, and fast deployment (≤6 months), serving biopharma, semiconductors, materials science, defense, and more.

Role:

We are looking for a CAE Simulation Engineer – LS-DYNA with hands-on experience in finite element modelling and nonlinear structural analysis. You will develop simulation models, perform explicit and implicit analyses, establish preload and pre-stressed conditions, and support engineering teams through virtual validation and design optimisation. The role requires strong fundamentals in FEA, LS-DYNA contact modelling, meshing, solver selection, and engineering interpretation of simulation results.

Key responsibilities:

• Develop and execute finite element models using LS-DYNA
• Create and modify CAD models in SolidWorks for simulation and analysis
• Generate high-quality meshes suitable for explicit and implicit analyses
• Define appropriate contact algorithms based on simulation requirements
• Select and implement LS-DYNA contact types including automatic, tied, surface-to-surface, node-to-surface, and eroding contacts where appropriate
• Perform both explicit and implicit analyses and select the appropriate solution methodology for each engineering problem
• Model structures using beam, cable, shell, and solid elements where applicable
• Apply Dynamic Relaxation (DR) methods to establish preload or pre-stressed conditions before transient or nonlinear analyses
• Validate preload conditions and ensure stable transition from preload to the primary analysis phase
• Perform nonlinear structural, transient, quasi-static, impact, or related analyses as required
• Review simulation convergence, energy balance, contact behaviour, mesh quality, and numerical stability
• Interpret simulation results and provide engineering recommendations for design improvements
• Collaborate with mechanical, structures, and design teams to optimise product performance and manufacturability
• Prepare simulation reports documenting assumptions, methodology, boundary conditions, results, and engineering conclusions

Qualifications:

• Bachelor's or Master's degree in Mechanical Engineering, Aerospace Engineering, or a related field
• Hands-on professional experience with LS-DYNA
• Strong understanding of finite element analysis fundamentals
• Strong knowledge of LS-DYNA contact definitions and their applications
• Understanding of contact selection criteria for different simulation scenarios
• Experience with beam and cable element modelling
• Strong understanding of explicit and implicit analysis methodologies and when each approach should be used
• Experience with meshing techniques and mesh-quality requirements
• Experience using Dynamic Relaxation for preload and initial-equilibrium conditions
• Ability to define appropriate material models, boundary conditions, loads, and constraints
• Strong analytical and engineering problem-solving skills
• Ability to interpret and communicate simulation findings clearly

Nice to have:

• Experience with nonlinear structural simulations
• Experience with dynamic impact, crash, transient, or quasi-static analyses
• Familiarity with preload and nonlinear boundary-condition workflows in LS-DYNA
• Experience with simulation-based design optimisation and validation
• Experience correlating simulation results with physical test data
• Exposure to aerospace, spacecraft, defense, automotive, or other high-reliability engineering applications

Compensation & benefits:

• Competitive salary (details will be shared with shortlisted candidates), 
• health insurance
• Provident fund.
