Startup jobs, with the salary parsed and the ATS named
Startup hiring data from Wellfound, formerly AngelList Talent: structured salary and equity, geocoded locations, the applicant tracking system behind each posting, and fill rates that swing 62 points between role categories.
Scrape Wellfound jobs
A walkthrough of extracting startup job listings: how Wellfound's URL-path filtering constrains what you can ask for, which caps actually bound a run, and what arrives in each row.
The Wellfound API question
There is no documented public endpoint for startup job listings. What robots.txt permits, what Cloudflare sits in front of, and which surface is actually readable.
The ATS spread
`ats_source` names the applicant tracking system behind a posting. Its fill rate varies by 62 percentage points across role categories, which is why the average is not published.
The column not shipped
Wellfound exposes a maximum years-of-experience value. It was filled on 2 of 2,229 jobs. Shipping it would have added a field that looks like data and is not.
Salary and equity parsing
Compensation on Wellfound is a display string. What it takes to split it into minimum, maximum, currency, period and an equity range — and why the original string still ships.
Cache age through a CDN
A row can be fetched seconds ago and still be a day old. Cloudflare's cache sat in front of Wellfound job pages at up to 23.4 hours, and `data_age_hours` counts it.
Rate limits and proxies
Wellfound rate-limits per IP, and the difference between a datacentre address and a residential one was 24 failures out of 36 against zero out of 48.
Pagination ceilings
Each role paginates until its own corpus runs out. Measured ceilings ranged from 37 pages to 130, which is why a fixed page cap is the wrong way to bound a run.
Field reference
All 58 fields grouped by what they describe, with the rate each was filled on across 2,229 jobs — and the three that are published as ranges rather than averages.
Why no people data
Founders, employees, funding rounds and investors are all on Wellfound and none of them are in the output. What the line is, and why it sits where it does.
