  • Support internal and external testing, audits, and pilot deployments.

  • Strong understanding of mobile authentication (EAP-AKA/ SIM-based auth).
  • Experience working with HSS, AAA, or IMS systems in real-world telecom environments.
  • Familiarity with GSMA standards (especially TS.43) is a strong plus.
  • Good system design and documentation skills.
  • Solid knowledge of backend systems, preferably with experience in Java-based environments.
  • Clear communicator who can work across technical and business teams.

Bonus Points For

  • Experience with 5G Core or GSMA Open Gateway APIs.
  • Prior work on entitlement platforms, provisioning systems, or SIM authentication flows.
