How we validate

Every listing passes the same five checks, or it is not published

Validation is not a claim about quality — it is a fixed sequence of tests applied identically to every vacancy, with an explicit outcome when a test fails.

How does KnowQaunt validate a job listing?

A vacancy is published only when it is read on an employer-operated careers system we track, survives deduplication against everything already held, resolves to a real city and country, and carries an annual pay range that is either employer-stated or a labelled benchmark band. Across 18 tracked boards, 1,333 vacancies from 18 employers currently meet all four; 182 of those quote the employer's own figure. Boards are re-read every six hours and vacancies that disappear are marked closed with a date rather than deleted.

The validation checklist

1 · Verifiable source

The vacancy was read on an employer-operated careers system we track, and the source link is stored with the record.

Passes: Stored source, employer, board type and the timestamp of the run that saw it.
Fails: Held back. Nothing reaches the index from an aggregator, a recruiter repost or a second-hand feed.

2 · Deduplication

A key of employer + normalised title + resolved city decides whether this is a new vacancy or a re-sighting of one already held.

Passes: The existing record's last-seen date is updated; the count does not move.
Fails: Duplicates never inflate a market, role or firm figure.

3 · Resolvable location

The free-text location must resolve to a real city and country pair, not a region, a placeholder or 'flexible'.

Passes: Locality plus country are published on the advert and in its structured data.
Fails: Counted in totals but excluded from every city figure, and never published as a listing.

4 · Labelled pay range

Either the employer stated an annual range in the advert, or our benchmark model produces a band for that role, seniority and market.

Passes: Published with an explicit label so you always know which of the two you are reading.
Fails: Implausible or non-annual figures are discarded rather than converted by guesswork.

5 · Re-checked and retired

Every tracked board is re-read on a six-hourly cycle and each vacancy is confirmed still live.

Passes: Last-seen date advances; the advert stays in the index.
Fails: The vacancy is marked closed with a date. It is never silently deleted, which is what makes time-to-close measurable.

Source traceability, worked through

Each listing keeps a reference, the run that first saw it, the run that last confirmed it and the stored source link. Employers are described rather than named in public, but the link is held against the record: quote a reference and we can re-read the board and publish a correction. These are live records, taken from the index as it stands right now.

What validation does not prove

It measures advertised demand, not total hiring. Senior quant seats — portfolio managers above all — are frequently filled without ever reaching a public board.
A benchmark band is a model output, not an offer. It is labelled as such everywhere it appears, and it never overrides an employer-stated figure.
Coverage is uneven by employer. Comparing two firms' vacancy counts is only meaningful where both have boards we read live.

The underlying rules — deduplication keys, skill terms, confidence bands — are set out in the data and methodology note, and quant relevance is derived in the Quant Signal Score.

Methodology

Figures are expressed as annual total compensation (base salary plus expected performance bonus) in the reference market's local currency, converted from a US dollar base. They describe typical market ranges rather than any individual offer, and exclude sign-on payments, deferred equity and carried interest. Portfolio-manager figures reflect formulaic profit-share arrangements and are therefore far more dispersed than any other role.
