Overview: Are you passionate about protecting digital assets and ensuring robust cybersecurity? We are seeking a dedicated and motivated Cybersecurity Network Engineer to join our team. Collaborate with engineers to secure network, cloud, and system infrastructure through implementing controls and monitoring.

You Will:

o Work with engineering teams to define and fulfill operational requirements while upholding the highest standards of security protocols and compliance.

o Monitor and maintain security for network, cloud, PKI, and system environments, implementing controls to safeguard information systems, applications, and infrastructure.

o Ensure access control systems effectively prevent unauthorized modification, destruction, or disclosure of sensitive information.

o Monitor, assess, respond to security risks in systems, networks, and clouds; find causes, identify threats, suggest solutions according to policies.

o Conduct security risk and vulnerability assessments, as well as business impact analyses for threats of moderate complexity in both on-premises and cloud environments.

o Develop detailed reports to pinpoint security risks and propose suitable mitigation strategies.

o Oversee and resolve user access issues, enforce least-privilege principles, and develop solutions to prevent future access-related security concerns.

o Assist with internal and external audits, providing necessary evidence and contributing to change management reporting and security impact assessments.

o Manage cloud security services like cloud proxy/VPN and XDR platforms for secure access and threat detection.

o Support PKI infrastructure, including certificate lifecycle management and secure key handling.

o Operate and monitor cloud network components and integrations, applying Secure Access Service Edge (SASE) principles to protect distributed users and cloud access.

o Implement and maintain network security controls such as firewalls, IDS/IPS, segmentation strategies, and enforce access control policies (ACLs, NACLs, identity-based segmentation) across hybrid environments.

o Investigate, contain, and resolve network-based security incidents, and contribute to comprehensive post-incident reviews.

o Collaborate with network and cloud engineering teams to ensure the secure design and implementation of cloud-native and hybrid solutions.

You Have:

o Proven experience in information security, cybersecurity operations, or a related field.

o Hands-on experience with cloud-based security services, network security controls, and incident response.

o Familiarity with SASE, firewalls, IDS/IPS, PKI infrastructure, and certificate management.

o Strong analytical and problem-solving skills, with the ability to assess complex security risks and develop effective mitigation strategies.

o Excellent communication and collaboration abilities.
