GraphRAG Developer Challenge

Overview

GraphRAG Developer Challenge – Legal Document Processing (Prototype)

Role & Details

• Role: Senior RAG Systems Developer (Contract / Freelance)
• Compensation: $600 — paid only if you pass
• 95% benchmark
• Timeline: 3–5 days from materials receipt to live demo
• Purpose: Technical evaluation for potential long-term hire
• Frontend / UI: None (backend prototype only)
• Contact: s.lilliu@revortis.com

Objective

We’re seeking an expert in graph-based retrieval (GraphRAG) to build a high-accuracy prototype for legal document reasoning. This is a paid technical test that may lead to a long-term position. The goal is a true GraphRAG system featuring explicit knowledge-graph construction and traversal, multi-hop reasoning, agentic orchestration, and strong focus on retrieval accuracy and explainability.

Materials Provided

• / docs / → Pre-processed Markdown legal documents with metadata
• / sample_questions.json → Example question format
• / sample_answers_rag.json → Example answer format

Download materials :

(Benchmark uses unseen questions.)

Deliverables

Implement two functions in Python 3.12 (Poetry project):

• def ingest(document_paths : List[str]) -> None
• """Ingest Markdown docs and build the knowledge graph."""
• def query(questions : List[str]) -> List[str]
• """Return answers with Vancouver-style citations grounded in retrieved sources."""

Requirements

No UI, no API keys provided. Any stack may be used. query(...) must support parallel execution (~400 questions in ≤60 min) and show a progress indicator. Test thoroughly for correctness and performance before the demo.

Live Demo

In a 60-minute live session you will :

• Receive ~400 unseen questions.
• Run query(...) to produce / answers.json.
• Explain your architecture : how the graph is built, traversed, and used to generate grounded answers.

Only the developer(s) who wrote the code may present.

Evaluation

Passing requires an overall score above 95%, measured by (LLM as a judge): Faithfulness (grounded, no hallucinations), Relevance (retrieval matches intent), Completeness (covers key legal points), and Clarity (structured, legally coherent writing).

Payment & Next Steps

If you pass, you’ll receive $600 USD after verification of reproducibility and hand-over of the repo (codebase, Poetry lock, run instructions, brief tech note). Top performers may be invited to interview for a long-term paid role. Failure to pass or complete within 60 minutes = no payment (you keep your code).

Key Priorities

Parallelization, graph-based reasoning, correctness, and explainability.

Note for Agencies

We will not engage in pre-contract discussions with agencies. If an agency wishes to propose a developer, communication will proceed only after that developer passes the benchmark test. This ensures time efficiency and direct technical validation.
