Answer:
ditch digger
Explanation:
Just as a "sanitation engineer" is a name given to a garbage collector, so "soil relocation engineer" may be another name for a ditch digger or grave digger.

There are many jobs in the mining and construction industries where engineering expertise is required with respect to appropriate relocation of soil. A <em>mining engineer</em> will need to relocate soil in such a way as to prevent cave-ins, slides, or pollution, while facilitating reclamation of the mine site when it is no longer productive.
A <em>civil engineer</em> will need to relocate soil using many of the same considerations as a mining engineer, but will also have to plan the moves so as to minimize cuts and fills, and to ensure adequate compaction for the construction to be done.
A <em>dredge operator</em> will perform soil relocation operations to or from underwater locations.
