Lisboa, Portugal Infinera Tempo inteiro

Research Engineer and Doctoral Student

The research and development work will focus on modelling and optimizing next-generation metro-aggregation networks leveraging coherent pluggable transceivers. The main objectives include:
(1) Assessment of appropriate line system architectures to cost-effectively support coherent pluggable transceivers capable of operating in point-to-point and point-to-multipoint modes.

(2) Implementation of fast and scalable optical performance models for short-/medium-reach transmission.

(3) Definition of multi-objective optimization problems targeting scalable and low-cost network deployment solutions and development of scalable optimization frameworks to solve them.

(4) Performance evaluation of the design algorithms developed. Assessment of cost, footprint and power-consumption metrics to compare the proposed architectures with state-of-the-art.

About the doctoral network NESTOR

NESTOR includes as beneficiaries and partners key industry players and prominent universities and research institutes: Infinera Unipessoal Lda (project coordinator, Portugal), Coriant R&D GmbH (part of the Infinera group, Germany), Politecnico di Torino (Italy), Technical University of Eindhoven (the Netherlands), Universitat Politécnica de Catalunya (Spain), Scuola Superiore di Studi Universitari e di Perfezionamento Sant’Anna (Italy), Aston University (UK), Instituto Universitário de Lisboa (Portugal), Orange (France), British Telecommunications (UK), SM Optics (Italy), VPI photonics (Germany), Ericsson Telecomunicazioni (Italy).

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. Execute detailed techno-economic comparisons.
- Implement simplified models to estimate optical performance in metro-aggregation networks using coherent pluggable transceivers and the selected node architectures. These models will be used to ensure the feasibility of the solutions obtained.
- Work collaboratively with other forward-thinking team members and external researchers from academic and industry.
- Write and present internal and public reports and deliverables.
- Write and present technical papers in high-impact journals and conferences from the IEEE and OPTICA.

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) and familiar with optical node architectures.
- Experience with optimization models and algorithms (e.g., integer linear programming models, heuristic algorithms).
- Knowledge of digital signal processing and optical transmission models.

Education / Experience:

- Master’s in electrical engineering/computer science/physics
- B2-C1 English Level
