Illumio Zero Trust Segmentation Platform Engineer
General Description
We are looking for a skilled Illumio Zero Trust Segmentation Platform Engineer to support the architecting and implementation of Zero Trust Segmentation policies, including application dependency mapping, labeling frameworks, enforcement boundaries, and zone-based controls. This role will assist in the design, deployment, configurations and optimization of Illumio Core and Illumio Edge across on-premises, virtualized and cloud environments.
The Zero Trust Segmentation Platform Engineer will develop Illumio workflows, runbooks, dashboards, and segmentation models for enterprise workloads and critical applications. Integrate Illumio with SIEM, SOAR, CMDB, C2C, vulnerability scanners, cloud-native controls, and enterprise automation pipelines. Conduct traffic flow analysis using Illumio VEN telemetry and assist in building policy recommendations to reduce attack surface and limit east-west movement. Troubleshoot system performance, VEN installation issues, policy conflicts, and platform health across distributed infrastructure. Partner with application owners to onboard workloads, validate segmentation plans, and support change management processes. Perform lifecycle management, including upgrades, health checks, certificate operations, and policy governance. Collaborate with security architects to align Illumio policy models with broader Zero Trust and NIST 800-207 strategies. Contribute to architectural standards, documentation, and enterprise security playbooks.
