Job Description Aerospace Design & Validation Engineer – Rocket Motors & Missile Systems

Company: IG Defence
Department: Aerospace Engineering / R&D
Experience: 2+ Years
Employment Type: Full-Time
Location: Noida / Ghaziabad

Job Summary

IG Defence is seeking a skilled Aerospace Design & Validation Engineer to support the mechanical design, engineering analysis, simulation, testing, and validation of aerospace structures, rocket motor assemblies, and missile-system mechanical subsystems.

The ideal candidate will have hands-on experience in CAD modelling, structural analysis, Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and engineering design validation, preferably within the aerospace, defence, propulsion, or UAV industry.

Key Roles & Responsibilities

• Develop 3D CAD models, mechanical assemblies, engineering drawings, and design documentation for aerospace and defence hardware.
• Support the mechanical design and integration of rocket motor assemblies, structural components, housings, interfaces, and support structures.
• Perform structural analysis and design verification under defined mechanical and environmental load conditions.
• Conduct FEA using ANSYS Workbench or ANSYS Mechanical for stress, strain, deformation, modal, buckling, and thermal assessments.
• Support CFD analysis using ANSYS Fluent for relevant aerodynamic and thermal-flow applications.
• Perform design verification and validation through simulations, engineering calculations, inspections, and controlled testing.
• Correlate simulation predictions with experimental or test data and document findings.
• Optimize component designs for weight, strength, reliability, manufacturability, and performance.
• Support material selection, tolerance analysis, GD&T, and Design for Manufacturing and Assembly (DFMA).
• Prepare Bills of Materials (BOMs), technical reports, validation reports, test documentation, and engineering specifications.
• Coordinate with propulsion, mechanical, avionics, GNC, manufacturing, and testing teams for subsystem integration.
• Support prototype fabrication, assembly, inspection, and hardware validation activities.
• Investigate design discrepancies and test failures, identify root causes, and recommend corrective actions.
• Maintain engineering drawings, revision histories, design configuration, and technical traceability.
• Follow applicable engineering standards, quality procedures, and laboratory and test-site safety requirements.
