You will join the Barclays SDN Operations team as part of a Broadcom-led group of 9 engineers, focused on upgrades and ongoing maintenance of VMware NSX and HCX platforms. This is a purely operational/upgrade-focused role, not a migration role.
Responsibilities
- Plan and execute upgrades and patches for VMware NSX in production and non-production environments, ensuring stability and minimal downtime
- Perform VMware HCX upgrades (appliances, connectors, service meshes) including pre-checks, execution, and post-upgrade validation.
- Carry out ongoing operational maintenance on NSX and HCX platforms, including configuration changes, health checks and remediation.
- Collaborate with the Broadcom SDN engineering team and Barclays SDN Ops to schedule and execute change windows under formal change management.
- Troubleshoot L2/L3 and security issues related to NSX and HCX components and coordinate with vendors as needed.
- Produce clear technical documentation: runbooks, MOPs, implementation and rollback plans, and post-change reports.
- Act as a Level 3 escalation point for NSX/HCX incidents and participate in problem management and RCA activities.
Required Skills & Experience
- 5–8 years of hands-on VMware infrastructure experience with robust exposure to NSX (NSX-T preferred).
- Proven experience with NSX upgrades and lifecycle operations in large enterprise environments.
- Hands-on experience in HCX platform upgrades; good understanding of HCX architecture and components.
- Strong networking fundamentals: VLANs, VXLAN/Geneve, routing (BGP/OSPF), firewalls, and micro-segmentation.
- Experience working in ITIL-based environments and regulated industries (e.g., banking or financial services).
