Description What’s the role? Westpac is delivering a large-scale Technology Simplification program, including the migration from Group Hogan to our internal Core Banking platform (TBK). We’re looking for a Senior Technical Business Analyst to join the Scaling stream, ensuring our applications and infrastructure are ready to handle up to 70% more transaction volume. You’ll work closely with 50 application teams to gather and translate requirements, supporting both applications and infrastructure uplift. This is a Sydney-based role with hybrid working (currently 2 days in the office, Mondays & Thursdays). What do I need? We’re looking for a senior BA who can work independently, manage multiple stakeholders, and bring a strong technical lens. You’ll need: Experience gathering requirements across both applications and infrastructure. Ability to collaborate with large numbers of teams and manage competing priorities. Strong understanding of infrastructure environments (front end, back end, middleware, integrations; mainframe desirable but not essential). Proven success delivering outcomes in complex financial services environments. Skilled in Confluence and Jira for documenting and managing requirements. Why join us? We’re obsessed with becoming our customers' 1 banking partner for life and we’re looking for people who are passionate about helping us achieve that goal.
