Contractor job Senior IT Project Manager – Private 5G

Notre client dans le secteur Énergie et ressources naturelles recherche un/une Senior IT Project Manager – Private 5G H/F

Description de la mission :

Context

A nuclear energy operator is preparing to deploy a Private 5G platform across two Belgian nuclear sites. The project aims to address end-of-life communications equipment, improve on-site connectivity and operational communications, enable future use cases, and meet EMC, cybersecurity, availability and nuclear safety requirements. A comprehensive technical study and system and user requirements have already been produced and will serve as the baseline for the RFP. The assignment does not include conducting a new 5G study, redefining the target architecture or repeating completed analyses.

Mission

Lead the end-to-end technical coordination of the Private 5G implementation and its integration into the existing IT environment. The role covers deployment across both sites, integration with IT services and applications, preparation of the solution for transition to RUN, and technical leadership of the RFP process for selecting a 5G integrator. After contract award, the role may optionally provide Owner’s Engineer support while preserving the client’s decision-making authority and the supplier’s delivery responsibilities.

Key responsibilities

• Coordinate a consistent Private 5G deployment across both sites, including 5G Core, RAN/radio infrastructure, SIM/eSIM and APN management, coverage and capacity, mobility and handover, performance, configuration, availability and resilience.

• Ensure compliance with IT, EMC, cybersecurity, nuclear security and nuclear safety requirements, and coordinate technical interfaces with the existing environment.

• Coordinate integration of 5G use cases and applications, network routing, firewall, segmentation, monitoring, support and transition to RUN.

• Develop the RUN and support model, clarify roles and responsibilities, and organise operational documentation, knowledge transfer, support processes and service reporting.

• Lead technical preparation of the RFP: review and refine existing requirements, identify gaps, define acceptance criteria, adapt the master schedule, and compile a complete, consistent and market-ready technical package.

• Define operational requirements, SLAs/KPIs, reporting, interoperability, vendor lock-in mitigation, data/configuration ownership and exit or transition provisions.

• Establish the technical evaluation and scoring methodology; coordinate bidder Q&A; assess and compare offers, deviations, risks and assumptions; and support clarifications, negotiations and technical contract finalisation.

• Define or coordinate testing, commissioning and acceptance, including FAT, SAT, coverage and performance, resilience, cybersecurity, integration, interoperability and application validation.

• If separately ordered, provide optional Owner’s Engineer support by reviewing supplier designs and deliverables, monitoring technical progress and risks, witnessing tests, reviewing acceptance evidence and supporting transition to operations.

Technical environment

• Telecommunications: Private 5G, 5G Core, RAN/radio infrastructure, SIM/eSIM, APN, DECT, VoIP, push-to-talk

• IT and network integration: routing, firewall, network segmentation, monitoring, IT service management, RUN transition

• Security and compliance: cybersecurity, EMC, nuclear security, nuclear safety

• Testing and acceptance: FAT, SAT, SLA, KPI

Expected deliverables

• Complete, consistent and market-ready RFP technical package

• Technical evaluation methodology, offer assessments and support for contract finalisation

• Testing, commissioning and acceptance framework, criteria and handover provisions

• RUN and support model, operational documentation and transition arrangements

• If the optional scope is ordered: supplier design and deliverable reviews, test witnessing and technical oversight outputs
