The problem

European IT staffing teams sourced a large share of open roles from Telegram channels — but recruiters spent hours scrolling unstructured posts, copying details into spreadsheets, and manually comparing candidates. Duplicate listings, missed roles, and slow shortlists made scaling dependent on hiring more people. Mainstream ATS tools covered job boards, not Telegram sourcing or explainable AI matching against an in-house candidate pool.

Solution

IT grows designed and shipped a multi-tenant recruitment automation platform spanning ingestion, matching, and recruiter workflow. Per-tenant Telethon workers ingest configured channels on a Celery schedule, parse and deduplicate vacancies, and normalize salaries, grades, and work format. Rule-based classification tags roles; Groq-powered LLM scoring ranks candidate–vacancy fit with transparent rationales. Recruiters work in a React web app — moderation inbox, applications kanban, candidate profiles with resume upload, and isolated workspaces per agency. The stack runs containerized on PostgreSQL, Redis, and FastAPI, deployed to production via GitLab CI and Kubernetes.
