Nordic Signals

Automated tracker for Nordic AI / infra hiring signals. Scrapes ~40 startup career pages daily, classifies new roles via GPT-4o-mini, and emails a weekly digest every Monday.

How it works

scrape.py    -> data/snapshots/YYYY-MM-DD.json   (all jobs today)
diff.py      -> data/diffs/YYYY-MM-DD.json       (added / removed vs yesterday)
classify.py  -> data/classified/YYYY-MM-DD.json  (added jobs + ML/infra tags)
notify.py    -> Resend email                      (Monday digest, last 7 days)

GitHub Actions runs pipeline.py every day at 06:00 UTC and notify.py only on Mondays. Snapshots are committed back to the repo so the next day's diff has yesterday to compare against.

One-time setup

1. Local install (only needed if running locally for testing)

   python -m venv .venv
   .\.venv\Scripts\Activate.ps1
   pip install -r requirements.txt
   python -m playwright install chromium

2. Verify the company list ATS slugs sometimes go stale. Open each URL once before first cron run:

   • Greenhouse: https://boards.greenhouse.io/{slug}
   • Lever: https://jobs.lever.co/{slug}
   • Ashby: https://jobs.ashbyhq.com/{slug}

   Edit companies.json and update / remove any 404s.

3. GitHub repo secrets (Settings → Secrets and variables → Actions)

   • ANTHROPIC_API_KEY — for the Claude Haiku classifier
   • RESEND_API_KEY — from resend.com (free tier covers this easily)
   • DIGEST_FROM — onboarding@resend.dev (or your verified Resend sender)
   • DIGEST_TO — your inbox

4. First run: trigger the workflow manually from the Actions tab. The first run produces a snapshot but nothing to diff against; from day 2 onward you'll get real signal data.

Local test

copy .env.example .env
# fill in OPENAI_API_KEY, RESEND_API_KEY, DIGEST_FROM, DIGEST_TO
python pipeline.py
python notify.py   # forces a digest email even mid-week

Adding a company

Append to companies.json:

{ "name": "NewCo", "ats": "greenhouse", "slug": "newco", "country": "SE", "tier": "growth" }

tier is informational only (scale / growth / early). country is ISO-2 (SE / NO / DK / FI / IS / EE).

Cost

• GitHub Actions: free (under 2000 min/month even running daily)
• Resend: free tier (3k emails/month — way more than needed)
• Anthropic Claude Haiku 4.5: ~$0.001 per job classified with prompt caching, so <€0.20/month at this scale
• Total: effectively free

Validation phase (weeks 1–4)

Forward each Monday digest manually to 10 hand-picked recipients (Stockholm recruiting agency founders, Nordic dev tool AEs, VC associates). Subject line: "fyi — Nordic AI hiring signals this week". Track replies. If 3+ ask to stay on the list, build the website (Phase 2).
