Lisboa, Lisboa, Portugal Phiture Tempo inteiro

Phiture is seeking a talented Research Engineer and Doctoral Student to join our Optical Architecture Group in Lisbon, Portugal. As part of the Doctoral Network (DN) NESTOR funded by the European Commission, you will conduct research on cost-effective deployment of coherent optical transceivers in metro-access networks.

The evolution of optical metro-aggregation networks will play a crucial role in supporting demanding applications such as 5G/6G, cloud services, and AI/ML. To achieve this, we need to significantly scale the capacity of these networks while maintaining low cost, power consumption, and footprint.

Main Objectives:

  • Investigate existing and new optical node architectures for metro-aggregation networks leveraging point-to-point and point-to-multipoint coherent pluggable transceivers.
  • Develop multi-objective optimization algorithms to design metro-aggregation networks considering potentially conflicting objectives such as low upfront deployment cost and long-term scalability.
  • Implement simplified models to estimate optical performance in metro-aggregation networks using coherent pluggable transceivers and the selected node architectures.

About the Doctoral Network NESTOR

The doctoral network NESTOR aims to investigate and develop solutions to cost-effectively deploy coherent optical transceivers in metro-access networks. This project will cover research topics ranging from digital signal processing to improved network design and operation techniques.

Essential Functions / Key Responsibilities

  • Investigate existing and new optical node architectures for metro-aggregation networks leveraging point-to-point and point-to-multipoint coherent pluggable transceivers.
  • Develop multi-objective optimization algorithms to design metro-aggregation networks considering potentially conflicting objectives such as low upfront deployment cost and long-term scalability.
  • Implement simplified models to estimate optical performance in metro-aggregation networks using coherent pluggable transceivers and the selected node architectures.

Knowledge / Skills / Abilities

  • Understanding of digital communications and telecommunications systems.
  • Knowledge of the most relevant subsystems of an optical communication system (i.e., transceivers, modulators, optical amplifiers, optical switches).
  • Experience with optimization models and algorithms (e.g., integer linear programming models, heuristic algorithms).

Estimated salary: €60,000 - €80,000 per year.
