## About the role

As the Lead Stress Analyst for Propulsion & Fluid Systems in the Mechanical Engineering department, you will provide technical leadership for the structural analysis of propulsion and fluid system hardware. You will own the structural integrity of engine and fluid-system components from early design through qualification and flight across multiple product lines. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Lead stress analysis of propulsion and fluid system hardware, including thrust chambers, feedlines, manifolds, valves, and pressurized components
- Perform and review static, thermal, dynamic, and durability (fatigue, fracture, and damage tolerance) analyses to guide design decisions and ensure strength, stability, stiffness, and life requirements are met
- Perform structural analysis using both finite element analysis (Ansys and/or Nastran) and classical hand calculations, and validate models against test data
- Define and improve analysis methods, standards, best practices, and material allowables for propulsion and fluid systems
- Generate interface loads and boundary conditions that drive sizing of downstream hardware
- Develop test requirements for qualification campaigns, correlate analysis models with test data, and support anomaly investigations and design improvements
