The Geotechnical Sub Alliance (GSA) is at the forefront of the Sizewell C nuclear power station development - one of the UK’s largest and most exciting infrastructure programmes.

We’re responsible for preparing the foundations of the entire site: designing and constructing cut‑off walls, retaining structures, soil improvements and more. Using advanced geotechnical engineering and world‑class construction technologies, this is a rare opportunity to contribute to a national project that will shape the UK’s clean‑energy future.

Employee Relations & Case Management: Manage a full range of Employee Relations cases, including disciplinary, grievance, absence, performance and restructuring, ensuring a consistent and compliant approach.
HR Advisory & Manager Support: Act as a trusted advisor to managers and employees, providing timely, pragmatic advice and coaching on people management and best practice.
Absence Management & Occupational Health: Coordinate Occupational Health referrals, manage absence processes, maintain accurate records and support effective return‑to‑work planning.
Recruitment & Workforce Planning: Support end‑to‑end recruitment activity, advising managers, ensuring compliance (including sponsored workers), and contributing to workforce planning initiatives.
HR Data, Reporting & Projects: Produce HR metrics and analysis to support decision‑making and client reporting, and contribute to HR projects such as organisational change, salary reviews and employee communications.
Wider HR Support: Provide general administrative and operational support to the HR team, contributing to the delivery of a responsive HR service in a fast‑paced, high‑pressure environment.
