• Targeted design activities that apply an appropriate workload placement strategy and maximise the benefit of cloud capabilities such as elasticity, serverless, containerisation etc.
• Best practice designs incorporating security principles (such as defence in depth and reduction of blast radius) that meet the Bank’s resiliency expectations.
• Solutions that appropriately balance risks and controls to deliver the agreed business and technology value.
• Adoption of standardised solutions where they fit. If no standard solutions fit, feed into their ongoing evolution where appropriate.
• Fault finding and performance issues support to operational support teams, leveraging available tooling.
• Solution design impact assessment in terms of risk, capacity and cost impact, inc. estimation of project change and ongoing run costs.
• Development of the requisite architecture inputs required to comply with the banks governance processes, including design artefacts required for architecture, privacy, security and records management governance processes.

Assistant Vice President Expectations

• To advise and influence decision making, contribute to policy development and take responsibility for operational effectiveness. Collaborate closely with other functions/ business divisions.
