Description du poste

A large public-sector organisation is transforming its information systems function while strengthening cybersecurity under NIS2 and the CyFun Essential framework. The scope combines organisational transformation with the practical adoption of security requirements across an information systems function. In this role, you guide the human side of both programmes, helping managers and colleagues adopt new responsibilities, processes, controls and ways of working.

The mission

The IS transformation aims to improve operational effectiveness, adapt the organisation, develop capabilities and evolve working practices. In parallel, NIS2 and CyFun Essential bring cybersecurity more firmly into daily work and strengthen organisational resilience. Your focus is adoption, not the technical implementation alone.

You embed change management in project governance throughout each initiative's lifecycle. You map impacts across the organisation, business activities, processes, tools and capabilities, then turn findings into communication, coaching and adoption actions. This includes helping managers and colleagues understand changing cybersecurity responsibilities, support the adoption of new security processes, controls and tools, and apply Security by Design in projects. You develop a proactive cybersecurity culture under NIS2 through awareness activities, a network of change ambassadors and security champions. Working with the wider NIS2 change lead and other stakeholders, you align communication plans across both programmes and address resistance before it prevents lasting adoption. You track changes in behaviour and practice, report adoption progress to transformation governance, and identify where further support is needed.

Your responsibilities

• Set the overall change management strategy and roadmap for the IS transformation and NIS2 programmes.
• Produce impact maps covering organisational, business, process, tool and capability changes.
• Assess stakeholders, engagement levels and resistance, then maintain mitigation plans.
• Coordinate communication plans, manager kits, awareness journeys and NIS2 adoption campaigns.
• Build and support a network of change ambassadors and security champions.
• Coach project teams, Product Owners, Project Managers and critical teams.
• Track ADKAR indicators, adoption KPIs and behaviour changes, reporting to transformation governance.

Your profile

Essential skills

• Confirmed experience in Change Management and organisational transformation.
• Experience with Information Security Management in IS environments.
• Experience of organisational transformation in the public sector and large organisations.
• ITIL knowledge and good understanding of IT service management processes.
• Good understanding of cybersecurity challenges and NIS2 requirements.
• Strong communication, active listening and influencing skills.
• Strong relational intelligence, empathy and facilitation skills.
• Ability to coach and support ambassadors, managers, colleagues and project teams.
• Ability to identify, understand and manage resistance in complex environments.
• Resilience, adaptability and a results-oriented approach in changing environments.
• Experience coordinating communication, awareness and adoption activities across complex stakeholder groups.
• Ability to work closely with programme change leads and transverse Change Management stakeholders.
