Role Description

We are seeking a Network Security Engineer to help execute and scale gFiber's network defenses. In this role, you will be responsible for delivering clear network security objectives and contributing to complex infrastructure projects. This is an opportunity to work hands-on with large-scale ISP routing security, internet-facing protocols, and boundary defenses.

You will make sound technical decisions with minimal guidance, using code to automate defenses and strengthen our overall posture. This role demands technical accuracy, a strong collaborative mindset, and the ability to provide clear security expertise to cross-functional engineering teams in service of gFiber's mission.

In this role, you’ll:

• Contribute to the architecture, deployment, and hardening of edge defenses and core routing infrastructure to mitigate large-scale attacks and safeguard gFiber's network boundaries.
• Drive execution on network security targets, making independent, sound decisions to secure our physical, virtual, and cloud network footprints.
• Automate network security workflows, configurations, and alerting pipelines using Python or Go to increase efficiency and eliminate manual friction.
• Provide advice and network security expertise during cross-functional infrastructure reviews, partnering with Network Engineering to embed security into their designs from the start.
• Identify areas of improvement across our network posture, proactively initiating changes and collaborating with leads and peers to execute them.

At a minimum, we would like you to have:

• Bachelor's degree in a technical field (e.g., Computer Science, Network Engineering) or equivalent practical experience.
• 5 years of direct experience in a security engineering, network security, or infrastructure security role.
• Experience with network security fundamentals (e.g., BGP, Firewalls, ACLs), analyzing high-volume traffic patterns, and mitigating external network threats.
