NI Eng & Delivery Programme Director in London

Sizewell C’s business is to design, finance, construct, commission, operate, maintain and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk. The Boards’ principal focus is on the development and construction of Sizewell C on time, on budget and to the highest quality and safety standards. Sizewell C is regulated by OFGEM under the RAB model. The construction strategy replicates the design of Hinkley Point C, with the CCO guided by lessons learned from Hinkley Point C to achieve savings in time and cost. After Final Investment Decision, the project is funded and owned by The Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.

Location: London, with relocation to Suffolk anticipated in 2029/30.

Salary: c.£180,000 (dependent on experience).

Benefits Package: executive bonus scheme and car allowance; family private medical insurance; 28 days annual leave plus bank holidays; contributory pension (up to 7.5% employee / 15% employer).

The role as Nuclear Island Programme Director involves full accountability for the end-to-end delivery of the Nuclear Island for both Sizewell C units. This is a career-defining leadership role responsible for a capital programme in excess of £10bn and central to the long-term success of the project.

You will be accountable for the complete EPCC lifecycle (Engineering, Procurement, Construction and Commissioning) of the Nuclear Island. Reporting directly to the Delivery Director, you will set the strategy, lead delivery and provide visible leadership across one of the most complex and safety-critical parts of the project.

You will lead a large, multi-layered programme organisation of circa 100 people at peak, including Programme Managers, Senior Project Managers and Project Managers, each responsible for major, interdependent work packages. You will build a high-performing, disciplined and delivery-focused organisation with strong project management capability, robust controls and a relentless focus on safety, quality and outcomes. The role also carries significant external exposure with regulators, investors and government stakeholders.

What you will be accountable for:

• End-to-end delivery of the Nuclear Island programme within agreed scope, safety, quality, time and cost baselines
• Defining and maintaining a clear Programme Execution Document outlining organisation, governance and delivery
• Building and leading a capable programme team with clear roles, accountabilities and performance expectations
• Driving safe, on-time and on-budget delivery across Engineering, Procurement, Construction and Commissioning
• Proactive management of risk, issues, change, cost and schedule with clear escalation where required
• Ownership of integrated programme schedules aligned to Level 1 and Level 2 plans
• Effective interface management with other Sizewell C programmes for coherent, integrated delivery
• Strong relationships with key suppliers and alliance partners to enable efficient and safe delivery
• Regular, clear reporting to senior stakeholders on progress, risks and performance

Nuclear safety: This role holds formal nuclear safety accountabilities, with activities that can directly impact nuclear safety. Responsibilities are defined within the Nuclear Baseline and require a strong safety culture, sound judgement and disciplined execution at all times.

The environment you will be operating in: Sizewell C is being delivered with technical replication of Hinkley Point C, drawing on the established nuclear capability of EDF and a global supply chain. Key stakeholders include the UK Government and its departments, regulators, financial investors, major alliance partners and the local community. The programme operates under intense regulatory, public and investor scrutiny, and demands exceptional leadership, transparency and control.

What we are looking for:

• Deep experience of nuclear new build projects and strong understanding of CDM Regulations
• Proven programme leadership across complex, regulated EPCC environments
• Strong grounding in recognised project and programme management methodologies (APM, MSP, PRINCE2 or equivalent)
• Demonstrable experience managing the full project lifecycle from concept through to handover
• Detailed understanding of quality management and assurance in nuclear or similarly regulated environments
• Strong command of cost, risk, schedule and change control, including Earned Value techniques
• Experience leading large, multi-disciplinary teams and managing complex supply chains and contracts
• Credible technical understanding of Nuclear Steam Supply Systems and nuclear I&C systems
• Excellent influencing, communication and stakeholder management skills

Qualifications and experience:

• Degree and chartered status in engineering, construction, physics or a related discipline
• Extensive experience managing contractors, consultants and advisors on major construction programmes
• Strong working knowledge of NEC and/or FIDIC forms of contract
• A proven track record of operating successfully under regulatory, safety and public scrutiny

Why this role matters: This is one of the most senior and consequential positions in the Sizewell C organisation. The Nuclear Island Programme Director will shape how the heart of the power station is delivered, influencing outcomes that will matter for decades. This role offers genuine scale, responsibility and national significance.

Behavioural Competences:

• Humility: Recognise the value brought from different cultures and experiences; be open to others' points of view and ideas, be willing to debate and to compromise
• Positivity: Positively challenge poor quality and performance; identify solutions at the lowest possible level; encourage tier 1s and others to bring new ideas forward
• Respect: Value the rules and environment in which we operate; give and receive feedback with respect; embrace and engage with new people and ideas
• Solidarity: One team, working closely together and helping each other; empowered teams always looking forward; shared responsibility for delivering the project outcomes
• Clarity: Communicate clearly and consistently; promote collaboration and team alignment; clearer and faster decision making; drive simplification at all levels

Location note: The role will be based in London initially, with a planned transition to Suffolk as the project moves deeper into construction.

Closing date: Friday 10th April 2026.
