Lead - Stage Designer

Key Responsibilities

• Lead Stage Functional Mechanical System design, realization and testing for LOX/Methane launch vehicle stages.
• Design & realization of functional mechanical systems of liquid propellant stage including fill & drain, feed, pressurization, vent & relief, POGO, slosh systems in accordance with input specifications from fluid system designers.
• Design & realization of various structural assemblies required for mounting, handling of stage components including valves, avionic packages, umbilical systems
• Interface structural and fluid system analysis teams to mature the design for development
• Interface with vehicle mechanical design team and identify interfaces for stage systems
• Interface with assembly & integration teams and perform developmental testing
• Interface with vehicle teams and realize the sub-systems required for fully functional stage and vehicle operation.
• Documentation of the designs and preparations of input documents for execution at various stages of system development

Desired Skills and Qualifications

• Master’s or bachelor’s degree in mechanical/aerospace engineering (preferred specialization in propulsion, fluid systems, or structural mechanics).
• 5–10 years of hands-on experience in mechanical system design and integration for aerospace or launch vehicle projects.
• Proficiency in CAD/CAE tools (CATIA, NX, SolidWorks, or equivalent).
• Strong knowledge of fluid system design and analysis tools (ANSYS Fluent, MATLAB/Simulink, or equivalent).
• Familiarity with structural analysis software (ANSYS, NASTRAN, Abaqus).
• Understanding of cryogenic fluid behavior, slosh dynamics, pogo oscillations, and mitigation techniques.
• Knowledge of QA/QC standards, aerospace material testing, and verification protocols.
• Direct involvement in liquid propulsion systems (LOX/Methane or similar cryogenic propellants).
• Proven track record in design, realization, and testing of stage-level mechanical systems (fill & drain, feed, pressurization, vent/relief, pogo suppression, slosh control).
• Experience in structural assemblies for mounting valves, avionics, and umbilical systems.
