"Location is not one field either: normalizing ten ATS job-board APIs down to city/region/country"

If employmentType is three different kinds of field wearing one name, location is worse — because on four of our ten platforms it isn't a field at all. It's a sentence someone typed into a text box, and the sentence doesn't agree with itself from one posting to the next on the same board.

We normalize ten applicant-tracking systems into one schema in ats-jobs-scraper, which means deciding, per platform, how city/region/country get filled — and when to leave them null instead of guessing. The short answer: three platforms already hand back structured geography, one hands back structured geography with a trap field disguised as a region, and the rest are free text that has to be parsed against a vocabulary that will never cover every string a human can type.

Structured, free text, or nothing

Structured, pass-through. Ashby, Lever, Recruitee, SmartRecruiters, Workable and Breezy all publish real city/state/country-shaped fields. Nothing to parse — the board already did the work. Re-verified live today: Breezy's two real boards (the-san-francisco-standard, breezy.breezy.hr's demo tenant) still fill country, region and city on all 9 of their combined postings, no nulls.

Structured, with one trap. Teamtailor's board feed embeds a full schema.org JobPosting, so city comes from jobLocation[].address.addressLocality — also structured, also a pass-through. But the field that looks like the obvious source for our region column, addressRegion, is not usable: re-checked live today across oatly (19 postings), schibsted (32), doconomy (1) and career.teamtailor.com (15) — 67 postings total — addressRegion is missing outright on 33 of them (schibsted's 32 and doconomy's 1, i.e. every posting on two of the four boards), and on the other 34 it's either a continent ("North America", "Oceania", "Europe") or a repeat of the country ("United States", "Sweden"). It is never a real state or province. We leave region: null for Teamtailor rather than ship a continent mislabeled as one.

Free text, parsed against a vocabulary. Greenhouse's location.name and Personio's office are both a single hand-typed string, and we run the same normalizer — parseLocation() — on both. Workday's list payload is a third flavor of the same problem: one string per posting, formatted differently by every tenant ("US, CA, Santa Clara", "France - Paris", "Canada, Toronto"), fed through the identical normalizer.

Nothing, until a second call. Workday's job-listing payload carries that one free-text string and nothing else — no separate country or city field exists on the list endpoint at all. The per-job detail call adds one structured field, which is where the real fill-rate jump below comes from.

Fill rates, measured live

* structured fields fill whenever the board itself populates them; not independently re-measured this cycle. ** re-measured live today on a fresh 177-posting pull (airbnb's board has grown from the 1,914-posting, 5-company sample behind the original 95/67/50% figures); directionally consistent, cited here as the single-board spot-check, not a replacement for the full sample.

Greenhouse: the trap isn't a bug, it's a tempting fallback we refuse to take

Greenhouse also publishes a per-posting offices[] array with a cleaner-looking name field, and the obvious move when location.name doesn't parse is to fall back to it. We measured why that's wrong once (1,914 live postings across airbnb, databricks, figma, stripe, discord) and it's stayed wrong: offices[] routinely contradicts the posting it's attached to. A databricks posting located in "Finland" carries a "Denmark" office. A "Nevada" posting carries a "Remote - Texas" office. Trusting the office array to fill a gap on one board invents a wrong answer, not a missing one — so we don't use it, ever, even when location.name fails to parse.

The California example is the clearest illustration of why the parser exists at all rather than a plain substring check on the raw text. Re-verified live today against the real airbnb board (177 postings, was 163 at last measurement — boards grow): locationKeyword: "California" returns 16 rows. Only 2 of those say "California" anywhere in the board's own location text — the rest are "San Francisco, CA", "Los Angeles, CA" and similar city strings our vocabulary resolves to the state. A buyer filtering on the literal word would miss 14 of 16 genuinely-matching postings.

Workday: the field exists, just not where — or when — you'd expect

Workday's list payload hands back locationsText, a free string, and nothing structured next to it. Running the same parseLocation() normalizer against that text (rather than leaving Workday at null forever, which is what the Actor did before this existed) fills country on 35%, city on 22%, region on 14% of 800 live postings sampled across nvidia, salesforce, adobe and okgov. Turning on includeDescriptions adds a second, per-job call that includes Workday's own structured country.descriptor field, and country jumps to 100% — its spelling, "United States of America", gets normalized to "United States" so it groups with every other platform's rows instead of forming its own bucket. That second call is also the only way to resolve postings the list page shows only as "3 Locations", which accounts for most of the extra city/region fill.

The practical effect, measured on the same 800 postings: locationKeyword: "United States" matched 0 before the detail-call resolution existed and 89 after.

That number was still wrong for one board shape, and the fix shipped in 0.1.39. okgov, a county-government tenant, writes its list text as county names only — "Muskogee County", "Craig County" — with no country or state anywhere in the string. The filter used to check locationKeyword against the un-resolved list text before the detail call that would have filled in country, so every one of those postings got dropped as a non-match even though the resolved value would have passed. Re-measured live on okgov after the fix: locationKeyword: "United States" went from 0 of 10 to 10 of 10. A later, larger re-check on the full visible board (60 of 60 postings, not the earlier 10-row sample) held: 60 of 60 matched, and the earlier proof generalized rather than being a sample-size fluke.

What we refuse to guess

Across every platform, anything the vocabulary doesn't recognize stays null. That specifically means: multi-country zones ("EMEA", "APAC"), placeholders ("N/A", the literal word "Remote"), internal office abbreviations ("SF", "CHI", "ATL"), and the single token "Georgia" — equally the US state and the country, so we carry neither. Real German place names outside our gazetteer ("Singen am Hohentwiel", the field-sales label "Außendienst Köln") come back null on Personio rather than a bad guess. Where a posting lists several places, the fields describe the first one and the rest stay in secondaryLocations rather than getting silently dropped.

Practical rules

• Structured fields don't need a parser; free text always needs a vocabulary, and a vocabulary is always incomplete. Budget for nulls — a wrong country is a worse answer than a missing one.
• Don't fall back to a "cleaner-looking" adjacent field without measuring it first. Greenhouse's offices[] looks like a gap-filler and is actually a source of contradictions.
• A field that looks like a region (addressRegion) is not always usable as one. Teamtailor's version is a continent or a country repeat — check what's actually in it before you map it.
• Order of operations matters as much as which fields you read. Workday's county-board bug wasn't a missing field, it was a filter running before the call that resolves it.

ats-jobs-scraper normalizes all ten platforms' location data into the same city/region/country/secondaryLocations shape, with locationKeyword/locationExcludeKeyword matching against the raw text and every normalized field at once. Pay per job posting returned, no start fee, no browser needed for any of the ten.
