Job description

We are looking for experienced Senior Technical Leads with strong Red Hat OpenShift experience to join a major enterprise infrastructure migration and platform modernisation programme within financial services.

• Strong VMware/vSphere experience within large virtualised estates

• Experience personally driving migration activity including discovery, dependency mapping, migration planning, wave sequencing, runbooks, cutover, rollback and stabilisation
• Proven ownership of technical migration workstreams through to successful delivery
• Ability to coordinate multiple engineering teams and resolve complex technical blockers
• Strong stakeholder management with the credibility to work with senior engineers, architects and programme leadership
• Experience within large, complex enterprise environments

Highly desirable:

• VMware VCF experience
• Experience migrating or modernising workloads from VMware/virtualised environments towards OpenShift or Kubernetes-based platforms
• Financial services or other highly regulated industry experience
• Large-scale data centre migration experienceInfrastructure automation and platform engineering experience

We are particularly interested in candidates who combine deep technical infrastructure knowledge with delivery ownership - people who can understand the detail, challenge technical teams where required, resolve problems and ensure migrations actually get delivered.
