What you’ll be doing:

• Lead financial modelling for major bids, rebids, contract extensions, variations and other pricing opportunities.
• Build, adapt and maintain fit-for-purpose models covering areas such as pricing, margins, cash flow, mobilisation costs, inflation, overhead recovery and commercial risk.

• Improve model usability, transparency and consistency by developing practical templates, controls and quality assurance processes.
• Support effective handover from bid to mobilisation and business-as-usual teams, ensuring key assumptions and pricing structures are understood.

You will bring strong commercial finance and modelling experience, ideally gained in bid pricing, tenders, contract pricing or complex commercial environments.
