Resource Development Group managing director Jeff Brill has stepped down from his executive role as the mining services group looks to cut costs.
He will be replaced by executive director Andrew Ellison, who joined RDG last year after its acquisition of the Centrals business.
RDG's board now comprises chairman Mel Ashton, along with Mr Ellison and executive director Richard Eden, who also joined RDG from Centrals.
In a statement today, RDG said Mr Brill advised the board of his intention to resign a part of the broader cost-saving initiatives across the company.
Mr Brill will remain as a consultant to RDG until the end of the financial year.
He has been in the role since the company listed on the ASX in 2011.
In January, RDG restructured its business operations into two divisions, after acquiring Central Systems in October last year.
Its consulting arms were brought together under the Engenium brand while its contracting arm will trade as Centrals.
RDG shares rose 2.8 per cent to close at 3.6 cents per share.
