For a project assignment with our well-known international customer in the high-tech sector in Bremen, we are looking for you as a Propulsion Subsystem Engineer for the Orion project.



As an overarching task the Propulsion Subsystem Engineer is supporting, or responsible for full-life cycle of the propulsion system for man-rated spacecraft; defining and/or overseeing the design, development, qualification, integration, and operation of the system and its components, interfacing with the system engineering team, and keeping safety at the forefront.

You are responsible for the following tasks:

- Analyse design & project requirements and perform trade-off between various design solutions for space vehicle propulsion subsystems and/or components.

- Support to service module team throughout integration and acceptance test phase

- Design, Development, and Qualification of complex system

- Design to requirements and verify compliance

- Preparation, review, and presentation at major design reviews (PDR/CDR/QR/FRR…)

- Lead propulsion system modelling using appropriate modelling methods and tools (such as ECOSIM).

- Lead analysis (Analysis of characteristics and performance).

- Assessment of test performance and build verification at all phases of test activities

- Performance analysis of the propulsion system

- Review of fluidic system interactions, cleanliness, and processes

- Define and manage interfaces, for mechanical and thermal aspects of the propulsion system

- Support to operations team, preparation of concept of operations, and inputs to flight parameters and user manuals

- Safely design, qualify, and operate systems and components of hazardous nature

- Responsible engineer from conception to end-of-life

Spacecraft Propulsion Development Engineering:
