We have over 650 staff working across 11 different countries. We work with distinguished clients such as the European Space Agency, EUMETSAT, NATO, European Commission, Canadian Government and national space agencies.
When you work for RHEA, you will have the opportunity to work alongside some of the best talented minds and experts in our industries, either working at our clients sites on some of the most exciting space missions or on cutting-edge projects in security, concurrent design, data and ground systems within our own offices.
To attract the best candidates, RHEA offers our employees competitive remuneration packages, unique career opportunities, individualised training and development programmes and local relocation support to take the stress out moving to another country or city. We are recruiting now. We understand your concerns during this period of a global pandemic and we will work with you, at your pace ensuring your questions are answered and maximum flexibility is offered.
On behalf of ESA, we are currently looking for a Structures Engineer to work in its Site (ESTEC) in the city of Noordwijk, The Netherlands.
Tasks and Activities
The scope of work will include:
- Structures Static, Buckling/Stability, Thermo-Elastic Analysis:
- Support the generation and set-up of mathematical models for structural thermo-elastic stability problems for Agency funded projects, taking into account specific requirements attached to this type of analysis.
- Perform the interpolation of the temperature maps as resulting from thermal analysis for their employment in finite element structural analysis.
- Perform thermo-elastic analysis leading to the determination of loads and deformations, evaluate the outcome in terms of margins of safety and stability budgets, evaluate critically the results and issue relevant documentation covering all analysis steps. Where necessary non-linear approaches shall be considered and specific solution sequences shall be developed.
- Design and Configuration:
- Support spacecraft and launcher configuration studies for Agency projects. This includes operating CAD tools and participation in Concurrent Design Facility (CDF) sessions at ESTEC.
- Perform mass, inertia and balance calculations and relevant budget assessments.
- Issue relevant documentation covering all configuration definition aspects, and where necessary shall support the configuration definition by preliminary structural analyses using FEM models.
- Ensure CAD interfaces and configuration data transfer with Agency contractors via international standards.
- Ensure the interface between the CAD systems and the relevant FEM tools to enable further evaluation of the structural behaviour.
- Contribute to the further development of the Structures and Configuration tools deployed in the Agency, including in the CDF.
- Support progress meetings and reviews in support to Agency projects.
- Support the updating and maintenance of CAD and FE models databases.
- Support and contribute to the establishment and maintenance of relevant Structures Engineering Standards and Handbooks.
- Evaluate critically the results and the loads and issue relevant documentation.
- Structural Dynamics:
- Support the generation and set-up of structural dynamic mathematical models for spacecraft and launchers of Agency funded projects using the finite element method. He/she shall take into account the specific objectives of such analysis and where necessary non-linear approaches shall be considered and specific solution sequences (e.g. Nastran DMAPS) shall be developed.
- Perform the analysis (modal, frequency and transient responses, random responses, preliminary in-house launcher – spacecraft coupled analysis), evaluate critically the results and issue relevant documentation covering all analysis steps.
- Produce advanced reduced models of spacecraft and launchers.
- Set up relevant documents and maintain all models and tools required to perform launcher – spacecraft coupled loads analysis.
- Dynamic Test Data Analysis and Correlation:
- Support the preparation and execution of mechanical tests (modal survey, sine, random, acoustics, micro-vibration, shock, etc) for spacecraft & launchers of Agency projects by performing and/or reviewing analytical predictions and procedures.
- Perform modal identification of the test data, evaluate critically the results and make usage of these results for updating structural finite element models.
- Perform assessments of shock response data.
- Take into account the specific objectives of such analyses and where necessary non-linear analyses shall be performed and specific solution sequences shall be developed.
- Issue relevant documentation covering all analysis steps. Where applicable produce advanced reduced dynamic mathematical models.
Skills and Experience
The following skills and experience are mandatory:
- in Aeronautical or Mechanical Engineering.
- Relevant experience within the field of spacecraft- and launcher structures design, analysis, verification and testing.
- Good knowledge in space system engineering, and space engineering standards (ECSS).
- Knowledge and experience of structures numerical analysis tools such as Nastran, Patran, Abaqus, ESACRACK etc.
- Good interpersonal and communication skills.
- Ability to work effectively, autonomously and cooperatively in a diverse and international team environment, defining and implementing solutions in line with team and individual objectives, as well as project deadline.
- Fluency in English, both written and spoken.
