About the Team

We are seeking a credible, experienced Finance Transformation Lead that as an individual contributor will help build a tech-enabled finance organisation that can keep pace with hypergrowth. Reporting to the CFO, you’ll scale processes, controls, reporting and data to public-company calibre—delivering across multiple concurrent workstreams, not a single programme.

You’ll handle systems and data projects, build robust financial models to support automated workflows and support the development of our control environment to listed-company standards. You will partner closely with Internal Audit to remediate findings and act as the bridge between assurance and delivery. Freed from line management and day to day operations, this is a connector role across Finance and the wider business; success comes from influence, pace, and outcomes. This role would suit someone with high intellect and drive, looking to supercharge their career in a hypergrowth environment.
