This role is primarily based on a secure client site and requires attendance on site five days per week due to the sensitive nature of the work and the systems involved. While the position is predominantly site-based, there may be occasional flexibility where business needs and security constraints allow. Any such arrangements would be agreed in advance with the project team.
