Feed System Functional Engineer

You will own the functional architecture and performance of the propellant feed system for a storable bipropellant propulsion system (MON3-MMH system). You will be responsible for ensuring the feed system delivers propellants to the thrusters within required specifications across the full mission envelope — from ground fill through operation, and recovery.

Role Overview

System Architecture

• Define and maintain the functional architecture of the feed system including propellant tanks, lines, valves, filters, thrusters and instrumentation.

• Perform system-level sizing, sensitivity analyses and functional simulations

System Development

• Define functional requirements for subsystems based on propellant system analyses

• Identify key verification and validation steps required at the system and subsystem level to demonstrate compliance with specification

Modeling & Analysis

• Develop and maintain fluid system models (steady-state and transient) to predict pressure drop, flow rates, water hammer, thruster cross-coupling, and priming behavior.

• Verify compliance between system nominal and off-nominal operation with subsystem operational domains (such as thruster envelope).

• Analyze failure modes (leakage, contamination, cavitation, fluid hammer) and define mitigation strategies and design margins.

Verification & Test

• Lead functional and performance verification: cold-flow, functional and hot-fire tests from component to assembly level .

• Correlate test data against predictive models and update margins/requirements accordingly.

Integration Support

• Support integration, qualification, and operations reviews (design reviews, FMEA, test readiness reviews).

• Interface across design, test, and operations functions throughout the vehicle lifecycle.

Location

You will perform your duties principally at the Company's premises in Bordeaux and may be required to travel from time to time to our company’s premises in Munich in the course of your duties.
