Your Role as a Cyber Security Architect – Telecom

As a Cyber Security Architect specializing in telecom, you will be at the forefront of designing and securing next-generation telecom infrastructures and networks for large-scale transformation programs. Your expertise will be instrumental in enabling critical use cases such as Mission Critical Communications (post-TETRA), Public Safety Networks, Non-Terrestrial Networks (NTN), and Industrial IoT. This role offers a unique opportunity to shape the future of secure telecom ecosystems while collaborating with industry leaders and innovators.

Your responsibilities will include:

• Designing end-to-end security architectures for telecom and cloud environments, covering domains such as SIM/eSIM, Devices, RAN, Transport (MPLS/IP), EPC/5G Core, IMS, MCx, OSS, and BSS.
• Developing and implementing security frameworks aligned with industry standards, including 3GPP, GSMA, ETSI, NIST, ISO 27001, and best practices such as Zero Trust, Defense-in-Depth, and Adaptive Security.
• Conducting threat modeling, risk assessments, and vulnerability analysis to identify and mitigate cybersecurity risks across telecom networks.
• Providing expert recommendations to address vulnerabilities and incidents, ensuring robust protection for telecom ecosystems.
• Evaluating and recommending security technologies, such as Firewalls, IDS/IPS, PKI, HSM, PAM, EDR, SIEM, and SOAR, while validating vendor solutions.
• Producing and maintaining high-quality architecture artifacts, including High-Level Designs (HLDs), Low-Level Designs (LLDs), guidelines, and security procedures.
• Collaborating with solution architects, engineering, and integration teams to ensure secure design and deployment of telecom solutions.
• Leading customer workshops and presenting security strategies to both technical and executive stakeholders, fostering alignment and understanding.
