Our client is a globally established, product-led technology organisation currently undergoing a large-scale platform and security transformation. They offer an excellent salary package, great benefits, and a very good team environment. With low attrition and a solid, experienced team, they provide a nice working environment and strong career progression opportunities. Having partnered with them for several years, we’ve seen their consistent investment in people and technology.
They are hiring a senior technical leader with a strong blend of .NET expertise, IAM knowledge, and leadership experience. This role requires someone who can operate across architecture and hands-on delivery, guiding teams through a complex modernisation journey.
