Clean Harbors runs hazardous waste, emergency response and industrial cleaning operations across North America, and its hiring is overwhelmingly operations-led, with field and site roles far outnumbering engineering. Its stack pairs Oracle Cloud ERP, Sales Cloud and Integration Cloud with legacy PeopleSoft, while Samsara and Rockwell/ABB/Wonderware point to fleet telematics and plant automation. Pain points center on OSHA/EPA compliance and work-site margin pressure.
