The Opportunity

Sizewell C is looking for an experienced Project Manager: Culture Change to lead the planning, coordination and delivery of our Leadership and Culture Programme.

Reporting to the Culture Transformation Lead, you will take ownership of a complex programme of work designed to support meaningful and sustainable culture change across the organisation. You will bring together multiple workstreams, stakeholders, suppliers and delivery partners, ensuring the programme remains on track and achieves its intended outcomes.

This is a highly visible and commercially focused role. You will be accountable for programme schedules, budgets, risks, dependencies, governance, reporting and benefits realisation, while ensuring that change is successfully embedded into business as usual.

You will also play an important role in developing and implementing change management strategies that maximise employee adoption, minimise resistance and create lasting business impact.

Why Join as a Project Manager: Culture Change?

This is not a traditional culture, communications or employee engagement role. It is a genuine project and programme delivery position with responsibility for turning culture ambitions into structured, measurable and sustainable outcomes.

You will have the opportunity to lead a varied portfolio of culture and leadership workstreams, manage significant programme budgets and work with stakeholders at all levels of the organisation. You will establish the governance, operating rhythm and controls needed to keep delivery moving, while ensuring the people affected by the change are properly engaged and supported.

The role offers a rare combination of commercial project management and organisational culture transformation. It would suit someone who enjoys bringing order and structure to complex programmes, can confidently manage competing priorities and wants to see the tangible impact of their work across an entire organisation.

You will act as a trusted partner and positive ambassador for culture change, balancing diplomacy with the confidence to challenge, make decisions and hold others accountable for delivery. The hiring brief particularly emphasises the need for someone commercially confident, excellent with numbers and budgets, highly organised, diplomatic and able to manage numerous priorities at once.

What You’ll Be Doing

As Project Manager: Culture Change, you will:

• Lead the planning, coordination and delivery of the Leadership and Culture Programme, ensuring workstreams are delivered to agreed time, scope, quality and budget

• Develop and maintain the overall programme schedule, working closely with workstream leads, business stakeholders and delivery partners

• Establish a clear programme operating rhythm, governance structure and appropriate decision making forums

• Manage programme budgets, costs and forecasts, providing accurate commercial and financial reporting

• Identify, manage and escalate risks, issues and dependencies across programme workstreams and business as usual activities

• Develop and implement practical change management strategies that support employee adoption and minimise resistance

• Create and maintain benefits realisation plans, ensuring intended programme outcomes are measured, achieved and sustained

• Manage programme change controls, including changes to scope, schedule and budget

• Produce clear workstream and programme status reports for Executive and Leadership teams

• Manage external partners, contracts, suppliers and technology providers involved in delivering programme outcomes

• Support the development and delivery of programme communications, stakeholder engagement, education and training activity

• Ensure appropriate project assurance, quality controls and gate reviews are completed

• Support workstream leads and team members by demonstrating best practice in programme, project and change management

• Oversee the successful transition of programme outcomes into business as usual with minimal disruption to the organisation

The role’s core outcomes are successful delivery against time, scope and budget, achievement of programme benefits and an effective transition into business as usual.
