Cyber Security Engineer – Illumio/ GCP / GCVE Migration Project

We are seeking a mid-to-senior level Illumio Engineer to support a large-scale migration initiative to Google Cloud Platform (GCP), including Google Cloud VMware Engine (GCVE). The ideal candidate will bring strong hands-on experience with Illumio and micro-segmentation technologies and be capable of contributing from day one in a fast-paced migration programme.

Project Overview

The project involves migrating applications currently hosted in colocation environments into GCVE and GCP. Existing applications are already micro-segmented, and the engineer will help extend, adapt, and optimise segmentation policies within the new cloud environment.

The team is currently standing up compute instances within GCVE and requires Illumio expertise to implement and manage micro-segmentation throughout the migration lifecycle.

Key Responsibilities

• Support the migration of workloads from colocation environments into GCVE/GCP.
• Design, implement, and maintain Illumio micro-segmentation policies across hybrid and cloud environments.
• Analyse existing traffic flows and segmentation policies to ensure secure migration and application communication.
• Assist with traffic analysis and dependency mapping for migrating applications.
• Work closely with infrastructure, cloud, and networking teams to support secure workload onboarding into GCVE.
• Configure and manage Illumio Policy Compute Engine (PCE) and VEN deployments.
• Support connectivity and integration work, including creation and management of required connectors.
• Collaborate on changes to the VMware load balancing solution as part of the migration to the target-state architecture.
• Troubleshoot policy enforcement, segmentation, and connectivity issues.
• Produce technical documentation and migration runbooks.

Required Skills & Experience

• Strong hands-on experience with Illumio or similar micro-segmentation technologies.
• Proven background in micro-segmentation and traffic flow analysis.
• Experience supporting cloud migration or hybrid infrastructure projects.
• Good understanding of networking concepts including TCP/IP, routing, firewalls, and application dependencies.
• Experience working within VMware environments.
• Familiarity with load balancing technologies and connector configuration.
• Ability to operate independently and contribute immediately with minimal ramp-up time.
• Strong troubleshooting and stakeholder communication skills.
