Managing Legal Counsel (Civils Alliance)

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. Overall, whilst the Company is in the construction phase, 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. The Company is maturing to meet all these requirements. Sizewell C is economically regulated by OFGEM under the RAB model similar to other UK electricity distribution networks and Thames Tideway. Sizewell C construction strategy is to replicate the design of Hinkley Point C, using the majority of the same supply chain, but innovating in the way it is delivered to achieve savings in time and cost of around 20%. The CCO will need to be guided by and incorporate lessons learned from the Hinkley Point C commercial delivery to achieve Sizewell C's ambition.

Following Financial Completion and Revenue Commencement, Sizewell C is fully funded and is owned by the Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.

Location: Based in London on a hybrid basis with travel to Suffolk as required. Contract: Permanent, full-time. Salary: Competitive dependent on experience, plus benefits.

• Annual Leave: 28 days per annum, increasing to 30 days after 5 years of service, plus bank holidays.
• Bonus: 5% annual bonus.
• Pension Contributions: Defined Contribution Pension Scheme with up to 7.5% employee contribution, 15% employer contribution.

Closing Date: Tuesday 5th May 2026. Sizewell C is entering an exciting phase of growth as we mature into an independent organisation and continue building one of the UK's largest and most important energy projects.

About the Role

We are seeking an experienced and pragmatic Managing Legal Counsel to join the Sizewell C Legal Team, to play a pivotal role in supporting the operation of the multi‑billion pound Civil Works Alliance, one of the project's most critical delivery partnerships. The successful candidate will provide strategic leadership on all legal aspects of Sizewell C's role and interest in the Civil Works Alliance, including governance and ongoing operations, ensuring robust contractual, commercial, and regulatory compliance across a complex, multi‑party alliance framework. This is a senior position within the Sizewell C Legal team, with line management duties and forming part of the legal management team (reporting directly to the Deputy General Counsel with a clear line to the General Counsel). You will provide strategic and operational legal advice to the Civil Works Alliance leadership team within Sizewell C, working closely with colleagues across Delivery, Commercial, Finance and Project Controls functions, as well as with alliance partners and senior stakeholders.

About You

• Proven experience advising on large‑scale infrastructure or energy projects.
• Excellent negotiation, drafting, and stakeholder management skills.
• Ability to provide clear, practical, and commercially sound legal advice in complex environments.

Key Competencies

• 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.

When joining Sizewell C, you may wonder why you are contacted by colleagues with an EDF email or see the EDF logo on portals that you access and/or documentation you receive; this is because we have partnered with EDF for the provision of a number of support services whilst we complete a successful transition out of the EDF group. At Sizewell C we encourage and embrace diversity and how it can improve our experience and performance at work. It is a requirement that those who join us have the right to work in the UK. Whilst sponsorship may be a possibility that we can explore, we are fully committed to local recruitment where possible, and those already holding the right to work in the UK. To be appointed to this role, you will need to meet the criteria for Security Vetting, which will, ordinarily, require you to have been a resident of the UK for at least three of the past five years.
