Security Engineer III

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Security Engineer III based in United States.

The Security Engineer III is a senior individual contributor responsible for security architecture, firewall infrastructure, standards, and security posture across a multi-site broadband environment.

You will own the firewall estate, establish consistent access-control and segmentation standards, and personally execute complex migrations and high-risk changes.

The role combines hands-on engineering with long-term roadmap ownership, compliance readiness, documentation, and technical program leadership.

You will work across network, security, infrastructure, compliance, vendors, and executive stakeholders to strengthen the organization’s overall security posture.

The position also serves as a technical incident commander for major security events and drives automation, policy-as-code, and drift detection.

Success requires someone who can operate independently, make architecture decisions, communicate with senior leadership, and remain deeply hands-on.

This is a remote role with proximity to a designated property required, alongside occasional travel, maintenance windows, and on-call responsibilities.
