• Working knowledge of networking, operating systems (Windows/IOS), and security protocols.

A bit more about what you will be doing:

You'll play a key part in strengthening our security posture by contributing to the development and enforcement of cybersecurity policies and procedures. You'll work closely with our IT and DevOps teams to embed security best practices into systems and software from the ground up.

Your day-to-day will involve assisting in threat hunting, risk assessments, and vulnerability management including running scans, analyzing findings, and supporting remediation plans. You'll actively monitor and respond to security alerts using tools like SIEM, IDS/IPS, and endpoint protection platforms. You'll also be involved in incident response efforts, from investigation and containment to resolution.

In addition, you'll help implement and maintain security controls across systems, networks, and cloud environments, support patch management cycles, and conduct regular audits of system configurations, access controls, and user permissions.
