Join a unique telecoms research environment focused on the technologies that underpin subscriber identity, authentication, and connectivity across modern mobile networks. As a specialist in eSIM and subscriber identity technologies, you'll bring expertise in areas such as eUICCs, Remote SIM Provisioning, GSMA standards, subscription management platforms, JavaCard, GlobalPlatform, and the wider ecosystem that enables secure access to telecommunications networks.
About the Role
You’ll work alongside experts in telecoms, cybersecurity, privacy, and hardware, applying your knowledge to investigate how subscriber technologies operate in real-world environments and how they are evolving to meet future industry demands. Your insights will help shape research activities, guide technical investigations, and contribute to discussions that inform government, industry, and academia.
Working in a collaborative and multidisciplinary team, you’ll have the opportunity to broaden your expertise into adjacent areas such as security, privacy, and telecoms resilience, while continuing to deepen your specialist knowledge. With access to carrier-grade telecom environments and the freedom to experiment, test, and explore complex systems, you’ll play a key role in advancing understanding of the technologies shaping the future of connectivity.
This is an exciting opportunity for someone who is passionate about telecommunications, curious about emerging technologies, and eager to contribute to cutting-edge research with real-world impact.
