HR Business Partner Manager (Sizewell C)

At Sizewell C, we are not just building a power station - we are building a legacy. As one of the UK's most ambitious infrastructure megaprojects, we are committed to delivering low-carbon energy for generations to come. Now, we are looking for a dynamic, strategic, and experienced HR professional to join our growing team at a pivotal time in the project.
In this maternity cover role, you will partner closely with our HR leadership and wider Business Partnering teams to deliver high-impact HR projects and provide expert guidance across the Sizewell C business. From optimising TUPE and IR35 processes to supporting business units with people strategy and workforce development - you will be at the forefront of enabling a high-performing, future-ready organisation.

Main Duties:

• Leading and delivering high-profile HR projects (including TUPE, IR35, and process innovation).
• Partnering with HR Business Partner Managers and their teams to support functional and delivery areas.
• Supporting workforce planning, performance, and talent management initiatives.
• Driving change, continuous improvement, and best practice in a dynamic and evolving environment.
• Acting as a senior point of contact across HR and the wider business, influencing and advising senior stakeholders.

Qualifications/Experience:

• A solid HR generalist background, with a track record of delivering complex people projects.
• Expertise in employment law, HR strategy, and partnering in a fast-paced or start-up/subsidiary environment.
• Experience with TUPE and IR35 (ideal but not essential).
• Strong stakeholder engagement and influencing skills.
• Flexibility, pragmatism, and a proactive, solutions-focused mindset.
