Field(s) of activity for the internship

Topic of the internship: Optoelectronic engineering

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. In these areas, the section is developing laboratory test setups and simulation tools.

Depending on your interests, technical competences and project constraints in 2026, you will support one or more of these developments by, for example:

• Development of simulation tools for free-space optical communications systems;
• Testbed development of advanced spaceborne optoelectronic applications (for optical communication, optical detectors and/or lasers);
• Integration and commissioning of upgraded laser induced contamination characterisation setup.

Behavioural competencies

• Result Orientation
• Operational Efficiency
• Fostering Cooperation
• Relationship Management
• Continuous Improvement
• Forward Thinking

Education

You must be a university student, preferably studying at master’s level. In addition, you must be able to prove that you will be enrolled at your University for the entire duration of the internship.

Additional requirements

The working languages of the Agency are English and French. A good knowledge of one of these is required. Knowledge of another ESA Member State language is an asset.

During the interview, your motivation for applying to this role will be explored.

Knowledge 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, LabView) or CAD, is an asset.
