Ledgerow

Ledgerow matches candidates to roles for mid-size employers. They already operate their own Kubernetes and did not want a second vendor console.

The open engine runs beside the applicant system. Each profile is a vector plus payload for location, seniority, and work authorization.

Recruiters filter authorization before ranking, which removed a class of illegal suggestions the old ranker produced and then hid.

Time to a first shortlist fell by 60 percent in this story, mostly because the filter and the search are one request.
