Estimateur de Coûts (H/F)

An innovative industrial decarbonisation company with global ambitions is seeking a CAPEX Cost Estimator / Cost Controller to support the delivery of a major first-of-its-kind low-carbon industrial project.

The organisation aims to develop, own, and operate large-scale green production facilities powered by renewable and low-emission hydrogen, with plans to replicate this model internationally.

The company is currently developing its first flagship plant in Southern France, representing a multi-billion-euro capital investment.

Reporting line: PMO Lead

Role Purpose

The Cost Estimator & Cost Controller supports the Project Department by developing, validating, and maintaining robust cost estimates throughout all project phases.

During the pre-FID phase, the role focuses on CAPEX estimating, benchmarking, and investment decision support from concept studies through FEED and detailed design.

During the post-FID / execution phase, the role transitions into project cost control, ensuring delivery within approved CAPEX/OPEX budgets, maintaining forecasts, identifying variances, and supporting management decision-making through reliable financial analysis.
