Title

Platform and Integration Architect Consultant

1. Project Background

The Asian Infrastructure Investment Bank (AIIB) operates a range of enterprise technology platforms and business applications that require reliable, secure, scalable and well-governed integration capabilities. As the Bank’s technology environment continues to evolve, the Information Technology Department (ITD) is seeking to further strengthen platform architecture, integration architecture, architecture modelling, technical standards and hands-on implementation support.The Bank currently uses an Integration Platform as a Service (iPaaS), namely the Boomi platform, to support application, data and process integration across its technology landscape. Broader architecture support is also required, covering platform design, deployment architecture, solution analysis, architecture modelling and visualization, and the development and continuous improvement of architecture standards, patterns and frameworks.The Consultant will provide domain-focused, hands-on architecture expertise, working in coordination with the Bank’s existing enterprise, solution and domain architecture functions and in accordance with the Bank’s established technology governance arrangements. The assignment is not related to any specific investment project but supports AIIB’s internal corporate systems and technology platforms.

2. Objectives of the Assignment

The objective of the assignment is to strengthen the Bank’s technical architecture, platform management and integration capabilities. The Consultant will provide architecture analysis, modelling, visualization, solution design and implementation support for enterprise technology platforms, with an initial focus on the Bank’s integration platform (currently based on Boomi) and associated integration capabilities.While the immediate priority is the Bank’s integration platform, the scope is not limited to a specific technology product or platform. The Consultant may support other enterprise technology platforms, technical architecture initiatives and related assignments based on the Bank’s evolving priorities.
