ACBS Application Support SME

About this role

Role Purpose
We are looking for an ACBS SME to support a core banking transformation program for a client based in the Singapore. The SME will own the commercial lending product stream (ACBS), driving requirement analysis and To-Be solution design for loan origination, servicing, disbursement, and repayment.
This is a core banking implementation role. The candidate must have hands-on, end-to-end experience delivering core banking transformation programs (not advisory-only exposure), and must be comfortable working directly with product vendors to challenge, validate, and finalize the To-Be system design.

•
Act as the subject matter expert (SME) for the product/module during requirement analysis, solution design, build, testing, and cutover phases of the core banking implementation.
•
Engage directly with product vendors to clarify product capability, configuration options, gaps, and constraints, and drive decisions on the To-Be system design.
•
Lead and/or contribute to workshops with business stakeholders, interface teams, the Solution Architecture team, and platform vendors to gather and validate requirements.
•
Prepare and own Interface Specification Documents (ISDs)/functional and technical design documents, and drive review sign-off with upstream and downstream teams.
