We’re seeking a Senior Systems & Network Engineer who brings a strong security mindset to traditional infrastructure engineering. This is not a pure security role—it’s ideal for someone who has spent most of their career working in systems, servers, networking, firewalls, and infrastructure, and has also been involved in security troubleshooting, incident response, or remediation. You’ll help strengthen our security posture by applying practical knowledge of how systems and networks behave, where vulnerabilities hide, and how to detect and fix issues efficiently.
Job Responsibility:
Manage and support core infrastructure including servers, networks, virtualization, cloud services, and firewalls
Investigate and remediate security issues by leveraging your understanding of how systems and networks operate
Assist with vulnerability management, patching, endpoint hardening, and incident response efforts
Monitor and improve environment performance, availability, and overall health
Support upgrades, migrations, and implementations across systems and network components
Collaborate with security teams, IT leadership, and business stakeholders to ensure infrastructure stability and security
Document environments, create runbooks, and contribute to best practices
Requirements:
Strong background in systems administration (Windows and/or Linux), server management, virtualization, or cloud environments
Hands-on experience with networking fundamentals—routing, switching, firewalls, VPNs, load balancers, etc.
Practical exposure to security work, such as: vulnerability management
incident response or troubleshooting
log analysis / SIEM tools
endpoint or network hardening
patching and configuration best practices
Ability to understand how infrastructure failures and misconfigurations lead to security gaps
Experience working across hybrid, cloud, or on-prem environments
Strong problem-solving skills—able to diagnose and resolve complex issues across multiple layers
Excellent communication skills and the ability to work cross-functionally
Nice to have:
Experience with cloud platforms (Azure, AWS, or GCP)
