This position performs a variety of engineering tasks relating to plant reliability and performance efficiency, troubleshoots plant and equipment problems and responsible for the collection, processing and interpretation of production, thermodynamic, geologic and geophysical data necessary to recommend actions to maximize steam production and plant generation. This position may also undertake special projects as assigned by and through the Plant Manager.

The level of supervision will be dependent upon the incumbent’s classification level (IV or V) but all levels will perform a variety of assigned complex technical and professional work.

This position requires the incumbent reports for work on time and maintains satisfactory attendance in accordance with Agency policy;
Ensures work responsibilities are covered when absent;
