Senior Design And Development Engineer

ST Advanced Composites; Sriperumbudur; On-site; INR 900,000 - 1,300,000; Full time

Job summary

ST Advanced Composites seeks a senior design engineer to lead the conceptual and detailed design of aerospace/defense composite structures. You will develop 3D models and detailed drawings, perform multi-physics analyses, and collaborate with manufacturing to ensure producibility.

The role requires coordination with materials teams, support for testing, and strict adherence to MIL-STD and AS9100 standards; immediate joining is preferred.

Responsibilities

• Lead design of aerospace/defense composite and hybrid structures (radomes, pods, launch canisters, UAV fuselage/wing, pylons).
• Develop 3D CAD models, assemblies, and fully dimensioned 2D drawings in line with ASME Y14.5 and aerospace standards.
• Perform structural, thermal, RF design integration, vibration, and fatigue analyses using ANSYS, Abaqus, and HyperWorks.
• Ensure aerodynamic shape optimization in collaboration with aerodynamicists for radomes, pods, and UAV structures.
• Design and validate tooling, molds, jigs, and fixtures for composite layup and autoclave curing.
• Integrate stealth, radar cross-section reduction, and lightweighting in product design.
• Collaborate with materials and manufacturing teams to optimize prepregs, vacuum bagging, autoclave processing, RTM, filament winding, and additive manufacturing.
• Prepare and manage engineering documentation, BOMs, qualification test reports, and certification dossiers as per MIL-STD, AS9100, and CEMILAC/DRDO requirements.
• Conduct design reviews (PDR, CDR) with internal stakeholders, customers, and defense agencies.
• Provide mentorship to junior engineers and foster innovation in lightweight aerospace composite designs.
• Support ground testing and flight trials, analyzing test data for correlation and design validation.
