The Senior Infrastructure Engineer is expected to be a Subject Matter Expert (SME) covering
network infrastructure maintenance and support, with a strong focus on cloud technologies. This
role requires an in-depth understanding of how networks operate and are managed, particularly
within a hybrid cloud environment, which combines both on-premise and cloud-based resources.
This will entail configuring and managing network components, monitoring network performance
to identify and resolve bottlenecks or latency issues, troubleshooting any network problems that
arise, and implementing robust security measures to safeguard the network from unauthorised
access and potential threats. You are expected to:

• Configure and maintain various network devices and services (e.g., routers, switches,
  firewalls, load balancers, VPN) in both on-premise and cloud environments. New
  installations may occur in the event of an architectural change.
• Support IT infrastructure-related work, including maintaining internet connections, Wi-Fi
  access points, network upgrades, office builds, expansions, and relocations, with a focus
  on ensuring seamless connectivity to the cloud environment.
• Actively participate in engaging with Business Stakeholders, internal IT Teams, and
  Vendors to manage project outcomes related to infrastructure maintenance and
  upgrades.
• Lead network infrastructure design for architectural changes and actively participate in
  operation reviews within the Change Management process.
• Lead and participate in problem-solving efforts, service restoration, and minimising downtime
  and outages across both on-premise and cloud infrastructure.
• Demonstrate technical influence within and outside your team, driving best practices and
  increasing overall productivity in infrastructure management and security.
• Communicate your ideas effectively to achieve the right outcome for your stakeholders
  and team.
• Actively drive knowledge sharing and continuous improvement within and outside your
  organization, particularly in the areas of cloud networking and security.
• Liaise with ISPs and vendors to provide required services and infrastructure, including
  managing direct network connectivity between on-premise and cloud environments.
• Ensure network infrastructure complies with banking industry regulations and standards,
  addressing vulnerabilities and maintaining a strong security posture across the hybrid
  environment.
• Manage and support payment infrastructure connectivity, including SWIFT and BCS FAST payment systems, ensuring secure and reliable connectivity within the cloud environmentand to external partners.
