To support product development by ensuring compliance with security requirements, experience with project assessment and governance is needed. Definition and review of security best practices on IMS will be performed regularly. We are looking for someone who will not hesitate to engage in researching how to connect new technology for our benefit. Getting things done and solving problems with the team are essential to the team culture.
Tasks:
- Perform security reviews of projects as part of the internal security assessment process.
- Provide advisory support to project teams from a security and compliance perspective.
- Assess IMS architectures and designs (VoLTE/VoWiFi/5G IMS) against internal security requirements.
- Define, review, and help enforce internal security requirements for IMS-based solutions.
- Identify, assess, and document security risks, support risk acceptance and exception processes.

- Contribute to the development of security standards and best practices within the Deutsche Telekom environment.

- Signalling security and interconnect security (e.g., TLS, IPsec, authentication & authorization mechanisms) and relevant analytical/troubleshooting approaches
