Resident Engineers represents the client and are treated as employees of a company which they represent. They can quickly resolve a problem on site and minimise the risk of parts rejections due to quality failure, which would have led to production downtime.

The main responsibilities of a Resident Engineer are efficient response to issues, verification and analysis of a defect, immediate contact with a supplier to provide details (photos, shipping parts for analysis), frequent visits to a facility, participation in regular meetings, maintaining good relationships with plant engineers.
