• Collaborate with virtualization, storage, and networking teams to ensure integrated solutions.
• Assume responsibility for delivering outcomes aligned with business and security requirements.

Project & Architecture Contribution

• Contribute to infrastructure projects from design through implementation.
• Partner with cross-functional teams to deliver scalable, secure, and resilient solutions.
• Provide technical input for strategic roadmaps and architecture decisions.

On-call

• Participate in the Infrastructure Operations on-call rota to provide out-of-hours support for priority incidents.
