•    Develop security frameworks aligned with international standards (e.g., 3GPP, GSMA, ETSI, NIST, ISO 27001, etc.), best practices (e.g., defense in depth, zero trust, adaptive security) and organizational security policies.
•    Conduct risk assessments and threat modeling for Telecom environments.
•    Provide technical expert guidance to mitigate cyber security risks, vulnerabilities, weaknesses and incidents affecting the telecom environment.
•    Assess and recommend security technologies (e.g., Firewalls, IDS/IPS, Encryption, PKI, HSM, PAM, EDR, SIEM, SOAR, etc.) and validate vendor solutions against security requirements.
•    Lead and/or collaborate with solution architects and integration teams to ensure secure deployments.

Your profile
•    Master’s degree in computer science, information security, or telecommunications.
•    Min 10 years of experience in cyber security, including minimum of 5 years in Telecom environments.

•    Security of radio communication protocols: 4G/LTE/5G, GSM/2G/3G, GTP, SCTP, etc.
•    Security of transport networks (MPLS, IP, BGP, etc.).
•    Security of cloud and virtualization platforms (OpenStack, Kubernetes, Docker, OpenShift, VMWare, etc.).
•    Security of EPC/5GC core networks and interfaces: AMF, SMF, SMSF, UDR, 5G-EIR-BE, AUSF, 5G-EIR-FE, UDM, NRF, NEF, etc.
•    Security of MCx and IMS services.
•    Security of network management systems, OSS, and BSS.
•    Minimum Baseline Security Standard (MBSS) for hardening the configuration of telecom network elements. 

What we believe you will enjoy about working here
•    Working with cutting-edge telecom technologies, including 5G Core and cloud-native architectures
•    Opportunities to work on projects that deliver mission-critical services that are fundamental to the public safety of society and other critical national infrastructure
•    Opportunities to contribute to large-scale transformation projects for leading telecom clients
•    Continuous learning opportunities and strong career development support
