Most recruiting tools find candidates for a job. The Campaign Engine flips it and finds jobs for a candidate: every night it scans the job market and scores every new ad against every active candidate profile. By morning, each recruiter has a ranked shortlist.

• Query expansion that speaks the market's language. Profiles say "Mgr. Procurement", German job ads say "Einkäufer": 0 hits vs. 395. Titles are mapped to German occupations via a taxonomy, an LLM fallback and co-occurrence learning from the ads themselves.
• Occupation keys at ingest. "Sachbearbeiter Rechnungswesen (m/w/d) in Teilzeit" is recognised as an accounting role even when no word matches the profile.
• Fetch once, score locally. Four sources feed one market scan three times a day. Ads are cached for 45 days, so adding a recruiter costs nothing extra.
• Guardrails instead of silent failure. A missing location triggers a warning rather than a quietly nationwide list, and an exclusion term that would cancel the profile's own search terms is rejected, checked in both directions.
• Human in the loop, by design. Nothing is sent without a recruiter's explicit choice. Mails go out from the recruiter's own mailbox inside a Mon–Sat send window: 10 mailboxes, 30 mails each per day, and every push is logged in the CRM automatically.
• Verified delivery, deliverability first. Every send is tracked from queue to sent to opened, without tracking pixels or rewritten links. "Profile opened" is measured by a click on our own page, and hits in the first minute are flagged as corporate link scanners.

No meta-framework. React 19 + Vite with a custom build-time prerenderer (renderToString to static HTML per route, then hydrateRoot), so every route ships a complete first frame and still behaves as a fully interactive SPA.

→ 95+/100 mobile, 100/100 desktop on PageSpeed with all Core Web Vitals green, via inlined critical CSS, self-hosted fonts, deferred GTM (Consent Mode v2), AVIF and per-route code-splitting. → SEO/GEO architecture: separate URLs per language with hreflang, per-route metadata, BlogPosting and ProfessionalService JSON-LD, plus an automated hydration check so a mismatch can never silently kill the performance win.
