[IV-Jobs] Working Student AI / LLM (12-20h, up to €25/h), KEA / Native Research, Berlin

[Johannes Nass]

KEA is hiring: Working Student AI / LLM (m/f/d) in Berlin

We're building an AI-powered data intelligence platform that turns natural language into verified database queries. A user types a question — our system resolves intent, retrieves the right variables from complex enterprise databases, generates and verifies SQL, and returns a precise answer. No SQL skills required. No analyst bottleneck.

The technology combines LLM orchestration, semantic retrieval, hybrid search, cross-encoder reranking, and self-correcting query generation across fully isolated multi-tenant environments. Our first clients are in market research, but the platform is domain-agnostic.
We're a small team in Berlin, close to launch, and looking for a working student who builds fast and thinks clearly.

What you'd work on

  *   Prompt engineering and LLM orchestration at the core of the product
  *   Retrieval logic — embeddings, BM25, reranking, making search precise
  *   Shipping features end-to-end that go live to real users
  *   Architecture decisions — you're in the room, not outside it

Stack
Python, TypeScript, DuckDB, Supabase, n8n, Embeddings,
BM25 + Semantic Hybrid Search, Cross-Encoder Reranking, RAG,
NL-to-SQL, Intent Routing, Self-Correcting Generation,
Multi-Tenant Isolation, Role-Based Access

What we look for

  *   Strong Python — the entire backend runs on it
  *   Interest in LLMs, retrieval, or making AI actually reliable
  *   Have built and shipped something (GitHub, side projects, prototypes)
  *   Learn fast, debug methodically, take ownership
  *   SQL is a plus — curiosity is non-negotiable

You don't need to check every box — but we expect you to be genuinely strong in at least one or two areas. One real project beats ten online courses.

Terms

  *   Berlin (on-site, not remote)
  *   12-20h per week, flexible
  *   Up to EUR 25/h
  *   Start: ASAP
  *   Full-time down the road? Open to it — no pressure either way

How to apply
Short intro. One project you're proud of. Weekly availability.
Show us what you've built — that's worth more than any CV.
