Luxembourgish National Graduate Trainee in Opto-Electronics and Quantum Engineering Job Requisition ID: 20915 Date Posted: 24 September 2026 Closing Date: 15 October 2026 23:59 CET/CEST Publication Method: External Only Type of Appointment (learn more): National Graduate Trainee Directorate: Technology, Engineering and Quality Workplace: Noordwijk, NL Grade Band: F1 - F1 The ESA National Graduate Trainee (NGT) Programmes offer recent Master’s graduates the opportunity to gain practical, hands-on experience at ESA across a range of space-related disciplines. The programmes are essentially similar to ESA’s own Graduate Trainee Programme, notably in offering the same employment conditions. They however differ in one important respect: each NGT Programme is funded by an individual ESA Member State or Associate Member under a bilateral partnership agreement concluded with ESA.As a result, a representative of the sponsoring State participates in the selection process. In addition to assessing candidates against the requirements of the position, the selection may also include an evaluation of their background and knowledge of the space policies and related activities of the sponsoring State.LocationESTEC, Noordwijk, NetherlandsOur team and missionThe Optoelectronics Section provides functional support to ESA projects and carries out technological research and development (R&D) in the field of optoelectronic device technologies and applications. In particular, the Optoelectronics Section deals with the specification, development and characterisation of photonic component subsystems and active optical instruments, such as detectors and lasers operating in the UV to FIR wavelength ranges, fibre-optic sensors, lidars, optical communication systems and quantum technologies. Our team is staffed with around 25 engineers supporting all ESA projects and offers a unique opportunity to contribute on the challenges related to optoelectronic technologies required for ESA missions, spacecraft, instruments and equipment. In addition, we develop laboratory test setups and simulation tools in the areas of imaging detectors, optical communication and quantum communication.You are encouraged to visit the ESA website:http://www.esa.intField(s) of activity/research for the traineeshipAs a National Graduate Trainee, depending on the your interests, technical competences and project constraints, you will have the opportunity to support one or more of these developments:Development of simulation tools for optical or quantum communications systemsTestbed development of advanced spaceborne optoelectronic applications (for optical or quantum communication, optical detectors and/or lasers)Integration and commissioning of upgraded laser induced contamination characterization setupAssembly and commissioning of an optoelectronics test bench for the characterization of scientific digital CMOS image sensorsCalibrate and validate Lidar terminals for Guidance Navigation and Control and In-Orbit Servicing applicationsTechnical competenciesKnowledge of relevant technical and functional domainsRelevant experience gained during internships, project work and/or extracurricular or other activitiesGeneral knowledge of the space sector and relevant activitiesKnowledge of ESA and its programmes and projectsBehavioural competenciesResult OrientationOperational EfficiencyFostering CooperationRelationship ManagementContinuous ImprovementForward ThinkingFor more information, please refer toESA Core Behavioural Competencies guidebookEducationYou should have recently completed or be in the final year of your master’s degree in physics or a relevant engineering discipline.Additional requirementsKnowledge and background in working with optical laboratory setups (including lasers, detectors, free-space or fibre-based optics), real-time data acquisition or experience in programming and modelling (e.g. Python, MATLAB and LabView) or CAD would be an asset.You should have good interpersonal and communication skills and should be able to work in a multicultural environment, both independently and as part of a team.
