About the Program

Our client is one of Australia’s Big Four banks, undertaking a multi-year, business-led and technology-enabled transformation – one of the largest simplification and migration programs in Australian banking. The program is consolidating hundreds of discrete legacy systems and processes down to a streamlined core, retiring duplicated platforms and migrating the bank onto modern, automated “evergreen” platforms supported by persistent teams. The program involves well over a thousand people across multiple major work packages and runs over several years. As a Senior Business Analyst you will sit at the heart of this change – translating complex legacy estates into clear, migration-ready requirements that protect customers and data throughout cutover.

Role Purpose

You will lead requirements and analysis activities within a migration work package, partnering with product, engineering, data, risk and operations to define the current state, design the target state, and de-risk the migration path between them. You bring senior judgement to large, ambiguous problems and set the analysis standard for less experienced BAs in your squad.

Key Responsibilities

• Requirements leadership:

Elicit, analyse, document and prioritise business and technical requirements for the migration and decommissioning of legacy platforms, ensuring traceability from strategy through to delivery.

• Current- \& target-state analysis:

Map existing processes, data flows and system dependencies; define the target operating model and the transition states required to get there.

• Migration \& data analysis:

Define data migration rules, mapping, reconciliation and validation criteria; partner with data engineers to ensure completeness, accuracy and lineage across source and target systems.

• Cutover \& decommissioning:

Support cutover planning, dress rehearsals, fallback/rollback criteria and post-migration verification; contribute to decommissioning runbooks for retired systems.

• Stakeholder management:

Facilitate workshops and align product owners, architects, engineering, operations, risk and external vendors on scope, sequencing and trade-offs.

• Risk \& compliance:

Embed regulatory, privacy, security and operational-risk requirements (e.g. APRA CPS 230/234, Privacy Act obligations) into solutions and surface migration risks early.

• Agile delivery:

Write clear user stories and acceptance criteria, groom the backlog, and support PI/sprint planning, UAT and defect triage in a scaled-agile environment.

• Quality \& mentoring:

Set BA artefacts and standards across the squad, review peers’ work, and coach junior analysts.

Essential Skills \& Experience

• 10\+ years’ business analysis experience, including large, complex transformation or migration programs.
• Demonstrable experience delivering system migration, platform consolidation or core/legacy decommissioning work – ideally in banking or financial services.
• Strong data analysis capability: data mapping, reconciliation and the ability to interrogate data (SQL or equivalent) to validate migration outcomes.
• Proven process mapping and requirements skills (BPMN, user stories, use cases, acceptance criteria).
• Experience working in Agile/Scaled Agile (SAFe) delivery teams with tools such as Jira and Confluence.
• Excellent stakeholder, facilitation and written-communication skills, able to bridge business and technical audiences.
• Sound understanding of risk, controls and regulatory obligations in a banking context.

Desirable

• Direct experience on a Big Four or comparable tier-1 bank transformation program.
• Exposure to cloud migration, microservices or API-led integration and modern “evergreen” platforms.
• Knowledge of core banking, payments, lending, wealth or deposits domains.
• Familiarity with APRA CPS 230 (operational resilience) and CPS 234 (information security).
• Relevant certifications (e.g. CBAP, BCS, SAFe, AgileBA).
