Directorate: Technology, Engineering and Quality

This is a fixed-term appointment with an initial duration of 4 years. Depending upon performance and organisational needs, the appointment may be extended up to a possible maximum duration of 8 years.

Optoelectronics Engineer in the Optoelectronics Section, Optics, Robotics and Life Sciences Division, Mechanical Department, Directorate of Technology, Engineering and Quality.

The Optoelectronics Section provides functional support to ESA projects and carries out technological research (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.

The Section is staffed with around 25 engineers supporting all ESA projects and offers a unique opportunity to contribute on the challenges related to optoelectronic technologies needed for ESA missions, spacecraft, instruments and equipment.

Reporting to the Head of Section and within the technical fields described above, your main tasks and responsibilities will include:

• providing expert technical support and consultancy to ESA projects, programmes and general studies in the field of optical communication systems for space and related technologies and testing techniques throughout all project phases;
• participating in feasibility studies, project reviews and the evaluation of procurement proposals;
• identifying critical development problems and assisting in their resolution;
• contributing to the definition of technology development requirements and work plans for the Agency’s technology programmes;
• defining, initiating and managing R&D activities covering both long‑ and short‑term needs;
• fostering new application areas for multidisciplinary activities, placing emphasis on innovative concepts, cutting‑edge technologies and system architectures;
• laboratory activities, as required;
• monitoring applicable scientific and technological trends and maintaining state‑of‑the‑art expertise;
• contributing to the dissemination of the results of the activities performed and the transfer of knowledge across the Agency.

Your duties may also include supporting other activities within your field of competence.
