Ecolab sells water, hygiene, and infection-prevention solutions to businesses that run high-stakes operations like food production, hospitality, healthcare, and industrial plants. Ecolab pairs products with on-site service and data-led monitoring, so customers can keep environments clean, safe, and compliant while also reducing water and energy use. Ecolab also operates a large sales-and-service workforce alongside R&D and engineering teams that build and improve the underlying chemistry, equipment, and digital tooling.

Ecolab is headquartered in St. Paul, Minnesota and operates globally with employees spread across North America, Europe, Latin America, Asia Pacific, Greater China, and India, Middle East and Africa. Work setup varies by role, with many field and site-based jobs tied to customer locations, and some office roles offering hybrid or work-from-home options depending on team and country.

Ecolab is easy to access for students because the company keeps internships visible, pairs them with a clear “considered for full-time” message, and even runs an early development summit that feeds into internship applications. The hiring process is explained at a high level, but the public picture on timelines and follow-up is mixed across roles. Pay and benefits transparency is a real strength in job ads and benefits documents, while ongoing restructuring and limited published outcome metrics cap confidence on early-career stability and progression.
