How this list works: we read the public job boards that employers publish on Greenhouse, Lever, Ashby, SmartRecruiters and Workday, plus Google's and Microsoft's own career sites. Locations, regions and remote status come from what each posting says. AI skill labels are matched from each posting's text. Velza is not the employer and does not take applications. Always confirm details on the employer's site.
