Position Reference 973 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, BucklingStability, ThermoElastic Analysis Support the generation and setup of mathematical models for structural thermoelastic 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 thermoelastic 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 nonlinear 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 setup of structural dynamic mathematical models for spacecraft and launchers of Agency funded projects using the finite element method. Heshe shall take into account the specific objectives of such analysis and where necessary nonlinear 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 inhouse 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, microvibration, shock, etc for spacecraft launchers of Agency projects by performing andor 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 nonlinear 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 MSc. 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. How to Apply Looking to take your career to the next level? Interested applicants should submit their CV and Cover Letter to RHEAs Recruitment team at careersrheagroup.com no later than 17082021. Preference will be given to candidates eligible for an EU or national personal security clearance at the level of CONFIDENTIAL or above.
