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 skilled 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.
