Research Fellowship opportunity in the Directorate of Technology, Engineering and Quality. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow PostDoc in Low temperature radiation effects on space grade materials This post is classified F2 on the Coordinated Organisations salary scale. Location ESTEC, Noordwijk, The Netherlands Description The Materials Physics Chemistry Section is operating state of the art space simulation facilities vacuum, temperature, electromagnetic particle radiation as well as physical and chemical materials characterisation instrumentation within the Materials EEE components laboratory. It is providing engineering support to all ESA projects and development programmes in the area of Materials Physics and Chemistry, associated processes and environmental effects. The sections laboratory covers Physical analysis and characterisation of materials , chemical analysis and characterisation of materials, Cleanliness Contamination Control, Environmental evaluation groundspace effects including laboratory testing work as well as performance prediction and verification including inorbit post flight analysis of materials and associated processes. Interested candidates are highly encouraged to visit the ESA website. Fields of activitiesresearch ESA is facing new challenges from its future cryogenic missions, such as JUICE or other lunar exploration missions, due to the extreme low temperatures external materials will encounter. In some cases, appendages of the Juice spacecraft are expected to reach 20 K while orbiting Jupiter. Spacecraft charging can give rise to unwanted ESD electrostatic discharge effects which can lead to a complete mission loss. Lower temperatures typically affect the charging potential detrimentally, i.e. the charging risk increases by a few orders of magnitude. This is why a careful selection of materials and charging mitigation strategies is required. The aim of the activity is to work with ESA on the low temperature ESD facility able to expose samples down to 20K and analyse the charging behaviour at these low temperatures. In addition spacegrade materials shall be assessed with a novel DDS Dynamic Dielectric Spectrometer able to characterise dielectric properties from cryogenic temperatures up to 500C. In addition, the candidate will use the Materials and EEE Laboratory which is a stateoftheart lab offering facilities which simulate the space environment, including thermal ageing, thermal cycling, UVparticle radiation, atomic oxygen and outgassing. The properties of the exposed materials will be analysed using a variety of techniques, such as thermal analysis, thermal conductivity, flexural properties, microscopy optical and SEM, surface analysis XPS, Raman spectroscopy, FTIR, contact angle and mechanical analysis. Technical competencies Ability to conduct research autonomously Breadth of exposure coming from past andor current researchactivities Researchpublication record Knowledge relevant to the field of research Interest in space and space research Ability to gather and share relevant information Behavioural competencies Innovation Creativity Continuous Learning Relationship Management Self Motivation Communication Problem Solving CrossCultural Sensitivity Education Applicants should have recently completed, or be close to completion of a PhD in a related technical or scientific discipline, preferably in materials science, physicschemistry of materials or materials engineering, or applied physics. Preference will be given to applications submitted by candidates within five years of receiving their PhD. Additional requirements Applicants should have good analytical skills, good understanding of materials analysis techniques. Ability to perform experimental work in laboratory, and knowledge of the space environment vacuum, chemistry, temperature would be an asset. The working languages of the Agency are English and French. A good knowledge of one of these is required. Knowledge of another Member State language would be an asset. Other information For behavioural competencies expected from ESA staff in general, please refer to the ESA Competency Framework. The Agency may require applicants to undergo selection tests. The closing date for applications is 05 December 2017. In addition to your CV and your motivation letter, please add your proposal of no more than 5 pages outlining your proposed research. Candidates must also arrange for three letters of reference to be sent by email, before the deadline, to temp.htresa.int. The letters must be sent by the referees themselves. The candidates name must be mentioned in the subject of the email. If you require support with your application due to a disability, please email contact.human.resourcesesa.int. Please note that applications are only considered from nationals of one of the following States Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland, the United Kingdom and Canada and Slovenia as well as Bulgaria, Cyprus, Latvia, Lithuania, Slovakia as European Cooperating States ECS. Priority will first be given to candidates from underrepresented Member States. In accordance with the European Space Agencys security procedures and as part of the selection process, successful candidates will be required to undergo basic screening before appointment Apply HERE
