Silicon Photonics Design and Test Engineer (EP-ESE-BE-2019-103-LD)

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on

Job Description


Do you have experience in the design and evaluation of Silicon Photonics devices and systems? Would you like to contribute to developing the next generation of optical data transmission systems for CERN’s experiments and accelerators? Seize this unique opportunity to explore novel Silicon Photonics device and system designs to meet the challenges of transmitting data in a harsh environment.Take part !


As a member of the Electronic Systems for Experiments group , you will be able to contribute to all stages of optical link development from conception to performance evaluation in radiation environments, by holding the following responsibilities:

  • Design and simulation of Silicon Photonics Devices and Systems
  • Packaging (inc. fibre-attach and mechanical design of fibre handling tools) of Silicon Photonics Devices
  • Design, schematic capture and PCB layout of test boards for Silicon Photonics Devices
  • Laboratory characterization of the performance of Silicon Photonics Devices and Systems
  • Evaluation of radiation tolerance of Silicon Photonics Devices and Systems
  • Supervision of students and fellows working on Silicon Photonics Devices and Systems


Master's degree or PhD or equivalent relevant experience in the field of electronic engineering or applied physics or a related field.


  • Demonstrated experience in the Design and Simulation of Silicon Photonics Devices and Systems
  • Extensive experience in the high frequency packaging and fibre attachment of Silicon Photonics Devices including mechanical design of fibre handling tools
  • Initial experience in the design and layout of test PCB’s
  • Extensive experience in the laboratory characterization of the performance of Photonic Devices and Systems
  • Demonstrated experience in the evaluation of radiation tolerance of Electronic and/or Photonic Devices and Systems
  • Demonstrated experience with high speed electronics and interconnects

Technical competencies:

  • Design and simulation of optoelectronic systems
  • Knowledge and application of optoelectronic components: emitters, waveguides and detectors
  • Testing and measurement of optoelectronic systems
  • Layout of electronic circuit boards
  • Knowledge of radiation effects on electronics and mitigation techniques

Behavioural competencies:

  • Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind ; following through on new ideas and innovations; planning and implementing application.
  • Demonstrating flexibility: readily absorbing new techniques and working practices; proposing new or improved ways of working; actively participating in the implementation of new processes and technologies; adapting quickly and resourcefully to shifting priorities and requirements.
  • Managing self: working well autonomously; taking on activities and tasks without prompting; handling uncertainty and ambiguity calmly and effectively; remaining objective, focussed and productive in a stressful environment; focusing on solutions rather than problems.
  • Solving problems: being open to original ideas and creative options by which to address issues; continually driving change by seeking new ways to improve outcomes; assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely.
  • Working in teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals; understanding when teamwork is required to achieve the best results; including others accordingly and sharing information.

Language skills:

  • English: spoken and written: ability to draw-up technical specifications and/or scientific reports and to make oral presentations
  • French: ability to understand and speak French in a professional context would be an asset
