Businesses' own websites

Where a business has a website, we visited it and checked that it belongs to that business before showing it. A phone number is shown only when it is printed on the business's own site. 41 verified websites.

Employers' own career sites, Adzuna and USAJOBS

Where a local employer publishes its openings on its own career site (16 so far, including Samaritan, Carthage Area Hospital, River Hospital, the County and City of Watertown, local schools and BOCES, The Arc and Car-Freshner), we read them from there, the same list its careers page shows, and link each one to the employer's application page. Those replace the reposts of the same employer's jobs found elsewhere.

Current openings located in Jefferson County (862 from 197 employers), refreshed daily and linked to the employer's directory listing where we can match it. Gig-app ads, national staffing agencies and remote postings are left out. Employers we can't match get a page only when the postings show a local site (a federal duty station, or several different openings). · last refreshed 2026-10-26

Jobs by Adzuna (links go to the original posting); USAJOBS is the U.S. government's official job site (public domain).
