GraphRAG Developer Challenge – Legal Document Processing (Prototype)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: ******
Objective
We're seeking an expert ingraph-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.)
Deliverable
Implement two functions inPython 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 thedeveloper(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.
