We are looking for a Structures Engineer E3 to join our Ajilon Technology Aerospace team, working onsite at the European Space Agency in the Netherlands. Ajilon Technology Aerospace is a specialized Engineering consultancy with more than 30 years experience providing aerospace Engineers to our key partners in The Netherlands. Ajilon is a longstanding business partner of the European Space Agency ESA, with more than 115 employees recruited from across Europe currently supporting ESAs activities. General tasks to be performed Structures Static, BucklingStability, ThermoElastic Analysis Support the generation and setup of structural mathematical models using the finite element method for structural analysis problems for Agency funded projects, taking into account the specific objectives of such analysis, covering all structural materials applied in spacecraft and launchers. Where necessary nonlinear approaches and specific solution sequences shall be applieddeveloped e.g. Nastran SOL 600, Mecano, Abaqus. Perform the analysis, evaluate critically the results and issue relevant documentation covering all analysis steps. Support the generation and setup of mathematical models for structural elastic stability problems for Agency funded projects, taking into account specific requirements attached to this type of analysis. Perform stability analysis leading to the determination of buckling loads and deformations. Where necessary the post buckling behaviour shall be addressed, adequate nonlinear approaches used, and where relevant specific solution sequences shall be developed. Evaluate critically the results, and issue relevant documentation covering all analysis steps 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. Evaluate critically the results and the loads and issue relevant documentation. In addition the these tasks elements of the following tasks are foreseen 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. 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. To successfully perform the above mentioned tasks, the following background experience is required A Masters degree, PhD or equivalent in Mechanical or Aeronautical 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 deadlines. Knowledge of thermal analysis software ESATANESARAD and CAD software CATIA would be an asset. About ESAESTEC The European Space Agency ESA has sites in several European countries. The European Space Research and Technology Centre ESTEC is the largest site and the technical heart of ESA. This nursery of European space activities is located in Noordwijk, Netherlands. At ESTEC, about 2500 engineers, technicians and scientists work handson with mission design, spacecraft and space technology. Almost all ESA projects except launchers are managed from ESTEC. In Noordwijk, people work on science missions, manned space missions, Earth observation, telecommunications and navigation satellites. ESTEC provides extensive testing facilities to verify the proper operation of spacecraft, such as the Large Space Simulator LSS, acoustic and electromagnetic testing bays, multiaxis vibration tables and the ESA Propulsion Laboratory EPL.
