Job Description

NBI is looking for an experienced and enthusiastic Second Line Support Engineer who wants to jump in head-first and help build a mission-driven company from the ground up.


National Broadband Ireland (NBI) will be the designer, builder and operator of the ultrafast broadband network for rural Ireland.  It was established by Granahan McCourt (GMC), an international investor in technology, media and telecommunications with 30 years of experience partnering with governments, corporations and people to drive development of communications infrastructure.

NBI has presented its vision for world-class, gigabit-speed broadband for every home, farm, school and business in areas of the country which are not fully served by commercial operators (the “Intervention Area”). National Broadband Ireland will supply broadband to the one quarter of Irish people and premises which currently cannot access high-speed broadband through commercial services. It guarantees a level playing field for 1.1 million people, 540,000 premises including 100,000 businesses and farms, and over 600 schools.

You will have a passion for the latest fibre access- & microwave backhaul network technologies. You will have deep specialist domain expertise- or the proven aptitude to develop such, in fibre access- and microwave backhaul networks: including XGSPON and OMCI; microwave link budget preparation to performance and availability objectives; adaptive code modulation and MIMO. Knowledge of microwave and PON diagnostic methodologies, techniques and tools is an advantage; ideally extending to knowledge of Nokia access nodes and Network Analyzer – Fibre (NA-F) and microwave Element- and Network Management Systems.

You get the importance of teamwork and you understand the importance of developing a strong relationship with our Network Operations & Engineering teams as well as managing the performance of third-party vendors who will provide third-line support.

You will work with a diverse team of people - with ICT systems and operational process expertise; and you will be responsible for delivering specialist access network technical support to assure continuity of network service. You will also ensure, along with your colleagues in Network Operations & Engineering, that our partners complete the installation, commissioning and test of the access- and microwave backhaul network and supporting infrastructure to the highest standards.

Key Responsibilities:

  • Support optimal function and performance of all fibre access network elements: e.g. OLT & ONT; specializing in fibre access technologies, systems and diagnostics.
  • Support of design and implementation of bespoke microwave backhaul solutions incorporating: -
    • Access microwave topology design
    • High level and low-level design
    • Frequency planning
    • Link budget preparation to performance and availability objectives
    • Ensuring adherence to ComReg licensing regulations and guidelines for point-to-point microwave links
    • Support Synchronisation Solution operations
    • Support DCN integration and operations
  • Support the adherence to key operational processes.
  • Support the acceptance of new/enhanced network resources into production.
  • Support the resolution of complex single- and multi-domain issues.
  • Contribute to the performance management of the operations team and third-party contractors.
  • Contribute to an open team culture of excellence, efficiency and continuous improvement.
  • Develop a strong relationship with colleagues in the Network Operations Centre and the Customer Operations teams; as well as liaising with third-party vendor specialists who will provide third-line support.
  • Work with business stakeholders and IT to ensure the quality of documentation and ability to measure and manage the performance of the network to stringent KPIs.

Our ideal candidate will have:

  • 5/7+ years technology/operations experience in an ICT environment
  • A third level qualification in engineering, computer science, physics or similar
  • Ideally, domain knowledge across PON fibre access- and microwave backhaul networks.
  • Knowledge of Radio Access Network technologies is an advantage (3GPP 2/3/4/5G, WiMAX, NB-IoT, LoRa …).
  • Knowledge of Analytic Trouble Shooting (ATS) techniques; test methodologies and techniques; and an aptitude for analysis, prioritization and clear technical communication – to identify root causes of functional and performance problems and generate remedies and resolutions.
  • Excellent understanding of ICT operations
  • Excellent written, oral communication, reporting and presentation skills.
  • Excellent ambassador for NBI, promoting the organisation and role modelling NBI’s values.
