About The Position
We are seeking an experienced Network Engineer to support a data center network segmentation initiative focused on implementing micro segmentation and Zero Trust architecture. The role involves designing, deploying, and optimizing segmentation policies using Segmentation platforms. You will be part of the team that leads the strategic shift from traditional flat networks to highly secure, micro-segmented environments across on-premises data centers, global offices, and multi-cloud infrastructure. You will work closely with security, infrastructure, and application teams to improve east-west traffic visibility, reduce attack surface, and enforce least-privilege communication.
Requirements

- Create and enforce security policies for east-west traffic
- Integrate segmentation tooling with Firewalls, SIEM/SOAR platforms, and CMDB / asset inventory systems
- Analyze application dependencies and traffic flows
- Build and validate allow/deny rules and segmentation policies
- Support policy simulation, testing, and enforcement phases
- Monitor segmentation effectiveness and tune policies
- Troubleshoot connectivity issues related to segmentation enforcement
