The UK’s nuclear sector has entered a renaissance, with Nuclear Energy now a vital component as the country moves towards a target of Net Zero.
Assystem provides critical support to this mission, accelerating the decommissioning and remediation of our legacy assets with a view to enabling a swifter energy transition, in parallel overcoming some of the largest engineering and environmental challenges of our generation.
As a Global top 3 independent nuclear engineering organisation, Assystem is active across the full decommissioning lifecycle. In the UK, we work across the Civil and Defence nuclear estates, pioneering agile and fit-for purpose, customer-focused solutions, drawing on our established pedigree for delivery engineering excellence. Assystem have a proud heritage gained over decades both in the UK and overseas, (delivering, supporting, managing) some of the most complex engineering projects in decommissioning, repurposing legacy assets and key new build projects such as Hinkley Point C.
of the Role
This stakeholder management role is based within a Major Project Capability Integration team at Helensburgh and is responsible to Assistant Head Capability Integration.
This is a key role throughout the project lifecycle, proactively facilitating the bridge between the project delivery workstreams and end user stakeholders to ensure that activities are planned and completed to enable site readiness.
Facilitating stakeholder management and subsequent engagement to ensure integration between Programme and Naval Base stakeholders through systematic identification and analysis of stakeholders, understanding the impact on stakeholders to improve the likelihood of their adoption of the change, the planning and conduct of interactions to engage and communicate with them, ensuring their involvement and contribution throughout the project lifecycle at the correct time whilst supporting integration activities to existing facilities, governance and process.
Infrastructure project delivery is a challenging environment, with interdependencies between a number of programmes and projects against the need to maintain the military outputs of an operational naval base. The candidate will be required to deliver at pace and demonstrate effective application of programme and project management skills, tools and techniques.
