This is a brief role with about 8 short scenes of spoken dialogue.  All of the dialogue will be heard in the form of audio logs that are played back on various computer terminals.  This is a much less taxing role compared to EN121.  The dialogue is meant to be an "end of shift" type dialogue (where each shift lasts months at a time).  A little background about the character if it helps:

His name is Urtuh Gnu.  Was a successful engineer, even after losing several fingers in an accident.  He has a quick wit and is sometimes the "life of the party".  He left his current position to become a mining engineer for the increase in hazard pay and also because of the positive vision of the new company.

* Jun 8 edit:  Apologies for not including this info earlier... These messages are often recorded in a somewhat harsh and windy outdoor environment at the end of a physical work shift.  Plus they may have been recorded during the night.  So there may be some underlying concern for the character in some cases.  Added a rough image of one of the outdoor terminals.
