The Crew Engineer is responsible for the maintenance and monitoring of the station, its buildings and systems.
The person in this position has to think proactively and be able to think like a Martian in terms of active response to the physical environment at MDRS. In order for daily activities to proceed as scheduled, the crew engineer needs to routinely monitor the equipment being used by the crew and make sure it is ready for whatever is planned.
In addition, when systems fail, the crew engineer needs to diagnosis the problem and contact Mission Support with a plan for solving the problem. While the Crew Engineer generally has an engineering background, experience proactively maintaining functionally of a large facility and/or project is more important that actual engineering skills.
