will be responsible for securing data, applications, and infrastructure within complex MVNO

ecosystems.

Key Responsibilities

Architecture Design and Implementation

Develop and implement security architectures for both on-premises and cloud-based

infrastructure supporting MVNO operations. Define and enforce security standards for

MVNO-specific infrastructure, including subscriber databases, core network components,

and virtualized network functions (VNFs). Ensure the secure integration of MVNO systems

with partner and host networks.

Network and Infrastructure Security Controls

Implement and manage security controls across MVNO networks, focusing on access

management, identity and authentication, encryption, and monitoring. Design secure

configurations for key MVNO components, such as network switches, VPNs, firewalls, and

mobile network security layers. Ensure compliance with telecom regulations (e.g., GDPR,

CCPA) and industry standards like 3GPP for MVNO security.

Threat Management and Incident Response

Conduct threat modeling and vulnerability assessments specific to the MVNO infrastructure, including mobile core, RAN, and transport networks. Coordinate with the Security Operations Center (SOC) to monitor and respond to security incidents affecting MVNO systems. Investigate root causes of security incidents and develop strategies to enhance resilience and prevent recurrence.4. Collaboration and Stakeholder Engagement

Act as a security advisor for MVNO teams and stakeholders, providing guidance on security

best practices for network operations and customer data protection. Collaborate with cross-functional teams, including network engineering, operations, and regulatory compliance, to embed security requirements within MVNO processes.

Compliance and Risk Management

Conduct regular audits of MVNO systems to verify compliance with regulatory requirements

and internal security policies. Identify and assess risks specific to MVNO operations,

including roaming security, SIM fraud, and subscriber privacy, and develop mitigation

strategies. Keep updated on emerging threats and vulnerabilities within the MVNO sector

and recommend proactive measures.

Documentation and Training

Create detailed security documentation, including architecture diagrams, configuration

guidelines, and incident response playbooks. Provide security training and awareness for

MVNO and network operations teams to help identify and manage security risks.

Qualifications And Skills

Bachelor’s degree in Cybersecurity, Telecommunications, Computer Science, or a related field. Master’s degree or relevant certifications are a plus.

Experience

8+ years in information security with a focus on infrastructure and mobile network
security, ideally within an MVNO, MNO, or telecom environment.
Certifications:
GSNA).
Relevant certifications preferred (e.g., CISSP, CISM, CEH, AWS Certified Security Specialty,

Technical Skills

In-depth knowledge of mobile network security, MVNO/MNO architecture, and mobile core
security principles. Experience with securing cloud and on-prem infrastructure, especially
for telecom environments. Proficiency in security tools (e.g., SIEM, firewall management,
IDS/IPS) and mobile network security protocols (e.g., 3GPP, LTE, 5G). Understanding of
encryption, VPN technologies, and secure access methods for MVNO networks.

Soft Skills

Excellent communication and collaboration skills, with the ability to translate security requirements to technical and non-technical stakeholders. Strong analytical and problem-solving skills, particularly in the context of mobile network security.

Application Process

Please submit your resume and a cover letter highlighting your experience with
infrastructure and MVNO security.
