Appeal of Role This is a high-visibility role in a small, autonomous team that directly shapes how security is embedded across Entain's technology estate. You will work across cloud, on-premises, and hybrid environments, engage with new technologies like agentic AI, and have genuine influence over architectural decisions. The team values practical security over checkbox compliance, collaboration over gatekeeping, and continuous improvement over perfection.
