JustJoin.it Jobs Scraper — Polish Tech & IT Jobs

Claude / Codex skill to describe and setup this actor: SKILL.md

Scrape current IT openings from JustJoin.it — Poland's biggest tech board — with salary-aware filters and mapped tech-stack facts in custom.data.

• $0.90 per 1,000 jobs, no start fee — the cheapest JustJoin.it Actor on the Apify Store
• All 23 tech categories by default — full-board coverage, not a single search query
• Salary-aware filtering using source pay ranges; the shared flat dataset does not publish a per-contract salary breakdown
• Keyword, city, salary, recency and exclusion filters built in

What JustJoin.it data does this scraper extract?

Published postings follow nomad-agent-job-row-v1. The shared fields carry source identity, title and company, parsed locations, dates, the complete plain-text body when available, source markup when usable, and work type. Unavailable scalar facts are null; no parsed location is []. Source-only facts appear in versioned custom.data only when mapped there. See the Output example section for the exact dataset fields and diagnostic rows.

How to scrape JustJoin.it with this Actor

1. Click Try for free / Run — no login to the target site, no cookies, no proxies to configure.
2. Adjust the input (keyword, filters, maxItems) or keep the defaults.
3. Run it and export the dataset as JSON, CSV or Excel, or read it over the API.

Run it from your own code:

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("nomad-agent/justjoinit-scraper").call(run_input={"maxItems": 50})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["title"], "—", item["company"], item["url"])

Or a single HTTP call that runs the Actor and returns items in one response:

curl -X POST \
  "https://api.apify.com/v2/acts/nomad-agent~justjoinit-scraper/run-sync-get-dataset-items?token=<YOUR_APIFY_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"maxItems": 50}'

Input

Field	Type	Default	Notes
categories	array of ids	[] = all 23 categories	Tech category ids to fetch: 1 JavaScript, 2 HTML/CSS, 3 PHP, 4 Ruby, 5 Python, 6 .NET, 7 Scala, 8 C, 9 Mobile, 10 Testing, 11 DevOps, 12 Admin, 13 UX/UI, 14 PM, 15 Game, 16 Analytics, 17 Security, 18 Data, 19 Go, 20 Support, 21 ERP, 22 Architecture, 23 Other. Empty means every category — the source has no "all categories" query, so broad coverage means one request per category id; maxItems still caps the total returned. Narrow it to specific categories if you only want e.g. frontend roles. Ids may be numbers or strings — [1, 5] and ["1", "5"] both work.
keywords	array of strings	[]	Keep only postings whose title or skills contain at least one of these keywords (case-insensitive). Leave empty for all postings.
city	string	""	Keep only postings whose city or listed locations contain this text (case-insensitive), e.g. Warszawa. Leave empty for all locations.
experienceLevels	array (select)	[]	Filter by experience level (junior / mid / senior / c_level / manager, plus anything else the board uses, e.g. intern). The legacy c-level spelling is accepted and folded to c_level. Leave empty for all levels.
workplaceTypes	array (select)	[]	Filter by workplace arrangement (remote / hybrid / office). Leave empty for all types.
contractTypes	array (select)	[]	Keep only postings offering at least one of these contract types (b2b / permanent / mandate_contract / internship / any). Leave empty for all.
withSalaryOnly	boolean	false	Keep only postings that disclose a salary range.
salaryMin	integer	0	Drop postings whose top disclosed salary is below this (PLN-normalised). Postings with no salary are dropped when set. 0 disables.
postedWithin	string	any	Keep only jobs published inside this window. Use any for no date filter, or a duration — 1h, 24h, 3d, 2w, 6m. Jobs the source published no date for are kept rather than dropped. Replaces postedSince, still accepted for existing integrations.
titleExclude	array of strings	[]	Drop postings whose title contains any of these substrings (case-insensitive).
companyExclude	array of strings	[]	Drop postings whose company name contains any of these substrings (case-insensitive).
maxItems	integer	100	Maximum number of job postings to return across all requested categories. Set 0 for no limit.
maxPages	integer	5	Maximum number of result pages to fetch for each category (50 results per page). Increase to get older postings.
extractFullDetails	boolean	false	Advanced. Fetch each offer's page to add description, skillLevels, languages and companySize. One extra request per posting; fails open per posting.
cacheTtlSeconds	integer	1800	Reuse a recent fetch instead of hitting JustJoin.it again within this many seconds; set 0 to always fetch fresh data.

Output example

Every row follows nomad-agent-job-row-v1, the one shape shared by all of this fleet's job Actors. A row carries every field; null means the source did not publish that fact, and locations: [] means no usable location was parsed from the posting. Nothing is guessed.

{
  "schemaVersion": "nomad-agent-job-row-v1",
  "recordType": "posting",
  "source": "justjoinit",
  "id": "a1b2c3",
  "url": "https://example.com/justjoinit/jobs/a1b2c3",
  "title": "Senior Backend Engineer",
  "company": "Example Company",
  "locations": [
    "Bilbao",
    "Spain"
  ],
  "postedAt": "2026-09-02T00:00:00Z",
  "deadline": null,
  "description": "The complete posting body as plain text, exactly as the source published it — never truncated.",
  "descriptionHtml": "<p>The complete posting body as the source's own markup.</p>",
  "workType": "remote",
  "custom": {
    "schemaId": "nomad-agent-job-custom-justjoinit-v1",
    "data": {
      "latitude": "…",
      "longitude": "…",
      "skills": "…"
    }
  }
}

Field	Meaning
schemaVersion	Always "nomad-agent-job-row-v1".
recordType	"posting" for a job, "diagnostic" for a row reporting something about the run itself.
source	Which job source the posting came from, from the collector registry's vocabulary — not the Actor name.
id	Stable identifier for the posting within source.
url	Canonical public URL of the posting on the source site.
title	Job title exactly as the source publishes it, untruncated.
company	Employer name as published.
locations	Places the role is based, most specific first — e.g. ["Bilbao", "Spain"].
postedAt	When the source published the posting, ISO-8601 UTC (YYYY-MM-DDTHH:MM:SSZ).
deadline	Closing date for applications as an ISO-8601 calendar date (YYYY-MM-DD).
description	The complete posting body as plain text — never truncated, never summarised.
descriptionHtml	The posting body as the source's own markup, preserving lists, headings and links.
workType	Working arrangement: "remote", "hybrid" or "onsite".
custom	Facts only this source publishes, as {"schemaId", "data"}.

A run also emits diagnostic rows — recordType: "diagnostic" with a warnings array — when it has something to report, such as a source returning nothing. They are never billed and are easy to filter out on recordType.
