Job position pitch  

As part of AXA's strategy to become a tech-led organization and advance our Digital Transformation journey through the “One Network” initiative, Network Global Products are adopting a more simplified, flexible, scalable, and business-oriented approach. This transformation involves consolidating multiple network infrastructures into a single, resilient, efficient, and automated network that can be centrally managed, providing a seamless experience across geographies.

While supporting the strategic migration of applications to the cloud, this evolution enhances AXA's ability to respond swiftly to market dynamics, ensuring high service quality, operational efficiency, and a robust security posture. Concurrently, AXA will maintain its existing on-premises legacy data center infrastructure, focusing on reducing technical debt and transforming its core IT footprint.

Several factors drive this transformation, including the need for high-speed, direct connectivity; optimization of data center space; rethinking data center urbanization and IP services; aligning with green IT objectives and power consumption reduction; enabling automation and scalability in infrastructure provisioning; and shifting security paradigms towards simplification and tighter control.

Within this context, our Data Center and Cloud Network engineers are instrumental in designing, engineering, delivering, and supporting products and services that significantly contribute to the success of the One Network program.

Our Application Delivery engineers play a key role in supporting AXA’s “One Network” transformation by migrating VIPs from legacy Viprion hardware to modern virtual solutions on Cisco ACI Fabric. This migration enhances application availability, operational efficiency, and security across the organization. The F5 load balancing platform provides scalable, automated, and resilient application delivery to meet evolving business needs. This evolution simplifies management, accelerates incident response, and strengthens network capabilities. Ultimately, it ensures AXA’s network infrastructure remains flexible, secure, and aligned with our digital transformation objectives.
