Job summary

Centorrino Technologies Pty Ltd. is seeking a Senior Business Analyst to uncover a legacy application’s operating model and dependencies from business and technical stakeholders.

The role focuses on elevating resilience, continuity and supportability through evidence-based options and clear documentation. You will map current-state processes, assess risks across technology and vendor ecosystems, and develop future-state roadmaps with validation from stakeholders.

Qualifications

• Senior Business Analysis experience across complex government or large enterprise environments.
• Proven experience analysing legacy, ageing, unsupported or poorly documented applications and their surrounding ecosystems.
• Strong requirements elicitation and stakeholder engagement skills across business, technical and operational teams.
• Demonstrated capability in process mapping, business rules analysis, data-flow analysis, interface mapping and dependency analysis.
• Experience reverse-engineering existing systems where formal requirements and technical documentation are incomplete or outdated.

Responsibilities

• Lead structured discovery of an existing legacy application, its business processes, technology environment and supporting operating model.
• Engage business and technical stakeholders to understand how the application is used, supported and integrated with the broader technology environment.
• Document application functionality, business rules, processes, data flows, interfaces, dependencies, controls and operational procedures.
• Reverse-engineer and validate undocumented or poorly documented functionality and integrations using available system, process and stakeholder evidence.
• Map current-state processes and information flows, identifying key dependencies, manual workarounds, control points and potential single points of failure.
• Assess operational, technology, vendor, security, continuity and support risks associated with the current environment.
• Develop practical and evidence-based risk treatments to improve operational resilience and reduce reliance on key-person knowledge.
• Assess business continuity, recovery and support arrangements and identify areas requiring improvement.
• Develop and evaluate future-state options, considering business needs, technical constraints, risk, maintainability and implementation considerations.
• Develop a prioritised roadmap and implementation-readiness material to support future investment and technology decisions.
• Establish traceability between stakeholder needs, current-state findings, risks, controls, options and recommendations.
• Facilitate stakeholder validation to ensure documentation and findings accurately reflect the operating environment.
• Develop practical, maintainable documentation and conduct structured knowledge transfer to relevant business and technical teams.
• Support a smooth handover that leaves stakeholders with greater understanding, ownership and capability beyond the engagement.
