Our clients Optical Communication Technology Lab in Paris is seeking strong candidates for permanent research positions in digital signal processing (DSP) algorithms for coherent optical communications. This is a unique opportunity to join a world-class, multi-disciplinary laboratory, whose mission is to carry out cutting-edge R&D on ultra-high capacity long-haul transmission systems.

Working as part of the DSP team, you will be focused on research topics that may include: Calibration and compensation of component impairments design of advanced modulation formats novel and low-power demodulation algorithms fiber nonlinearity compensation strategies mitigation of cascaded in-line filtering effects and polarization-dependent loss application of machine-learning methods in coherent systems and DSP link impairment monitoring.

The research will be conducted in collaboration with teams spanning across multiple international sites.

Main responsibilities:

  • Come up with novel concepts and provide full solutions for our client's coherent ASICs
  • Validate algorithms via simulations and experiments
  • Interact with other internal teams, product line engineers and managers, to carry out joint projects, gather specifications and requirements, and communicate results
  • Generate intellectual property and file patents
  • Create and maintain strong collaborative associations with university-based researchers
  • Contribute to the creative and innovative atmosphere at the Paris Research Centre
  • Publish in top journals and conferences


  • PhD in optical communications and DSP, 0-3 years' experience after graduation.
  • Industrial experience is highly desired.
  • Strong background in DSP algorithms, digital communications and fiber transmission theory.
  • Proven research track record with publications in high-impact optical journals and conferences.
  • Excellent programming skills; expert in Python (preferred) and/or MATLAB, C/C++ is a plus.
  • Laboratory experience is desired.
  • English language spoken/written fluency and good communication skills.
  • Ability to conduct independent research while also contributing to team-oriented projects.
