If so, Gomez and Sullivan Engineers would like to hear from you.  We are a small, growing water resources consulting firm with a national reputation for excellence. We are seeking motivated individuals committed to continuing this tradition. Our company has an immediate opening for a Civil/Water Resources Engineer with experience in hydrologic and hydraulic modeling for watershed, river, reservoir, and dam studies at our Henniker, NH location.
