Lead Stress Engineer

Key Responsibilities

1. Perform linear and nonlinear static stress analysis of composite structures.

2. Conduct buckling analysis of composite panels, spars, ribs, and stiffened structures.

3. Perform fatigue and durability analysis, and apply appropriate composite failure criteria

4. Perform modal analysis to determine natural frequencies, mode shapes, and modal participation

factors.

5. Support vibration, resonance, and structural dynamic assessments for Flight loads, Payload-

induced excitations, Launch, recovery, and transportation conditions

6. Contribute to flutter margin assessments and stiffness tailoring of composite structures.

7. Collaborate with aerodynamics, propulsion, and systems engineering teams to ensure structural

integrity and performance.

8. Prepare technical reports, documentation PDR, CDR & TRR
