• Perform ad‑hoc analyses as required and provide recommendations and solutions based on analysis.
• Working with the wider treasury and finance teams ensure internal and external audit points are addressed and closed in a timely manner.
• Champion a culture of collaboration and continuous improvement.
• Inspire and engage colleagues by clearly communicating objectives and aligning goals with broader strategic priorities.
• Encourage technical excellence and capability development within the impairment modelling team.
• Actively support talent development by identifying skill gaps and mentoring junior team members.

• Process‑oriented approach to model governance, monitoring, and lifecycle management.
• Strong problem‑solving skills with the ability to interpret complex data and translate insights into actionable recommendations.
• Strong communication skills – able to present technical concepts clearly to both technical and non‑technical stakeholders.
