Job Search
Used by Job Search and echoed on every job row.Seniority ranks
seniority_ranks filter · seniority_rank response field. Resolved from the job title.
A value outside
1–5 matches nothing, so [7] returns no rows.
Job functions
functions filter · functions response field (array, null when unclassified). The same slug can appear on many titles; a title can carry several slugs. Matches any listed slug; an unrecognised slug matches nothing.
The most common slugs, in descending order of postings:
media_and_commmunication is spelled with three ms in the data, and the Department Functions catalog spells product_mangement and workforce_mangement. Either spelling works in functions and department_functions.information_security, supply_chain, devops) uses the same vocabulary as the slug column of Department Functions. The quickest way to discover slugs for a niche is to run an unfiltered search on a few relevant companies and read the functions array on the rows.
Job source types
source_type response field. linkedin for the large majority of postings; partner job boards report their own slug (wantedly, tw1111, rocketpunch). Older rows can be null.

Departments and functions
Job Search takes the same
departments values. Slugs and names match in any case, spacing or punctuation (information_technology and Information Technology are the same). A value that names no department or function whole is read as the one that holds all its words: engineering is read as master_engineering_technical. A word several of them hold names none.
