The Opportunity
auditable, evidence-linked decisions
What You’ll Do
1) Enterprise RAG & Knowledge Architecture
- Design multimodal RAGover PDFs (text/tables/images), CAD/vector drawings, MSDS/chemicals, and bilingual (KOR/ENG) regulations.
- Implement hybrid retrieval(BM25 + dense + metadata + knowledge graph) with reranking; target ≥90% top-k answerability andtraceable citations.
- Build domain embeddings for bilingual technical terminology; craft routing/prompting for audit-ready outputs.
2) Industrial Data & Change-Aware Pipelines
- Ingest/normalize heterogeneous sources (ERP/MES exports, legacy DBs, SharePoint, IoT streams).
- Ship 10k+ document-typeingestion with schema validation, redaction, andtemporal versioningfor regulatory drift.
- Integrate external APIs (e.g., KOSHA, OSHA, EPA; for finance modulesSEC/DART).
3) Production AI & MLOps
- Orchestrate ensemble decisioning(rules + priors + ML) withSLA < 10s; cost-optimized LLM flows (tool-use, caching, distillation).
- Operate on AWS EKS, Postgres, Pinecone,Temporal/Argo, Prometheus/Grafana; CI/CD with test & eval gates.
- Build explanation layers (attribution, chain-of-evidence; SHAP/LIME where applicable) and human-in-the-loop feedback.
4) Vision & Document AI (Nice to have)
- Table/figure/annotation extraction (LayoutLMv3/Donut/DocFormer), symbol detection (YOLOv8/RT-DETR), PDF vector parsing.
5) Client Co-Creation
- Lead deep-dive workshops with CxO/stakeholders; design PoCs that land $1M+programs.
- Mentor client teams and internal engineers; author crisp technical docs fit for audits.
What You Bring
Must-Have
- 7+ years building production AI/ML or search systems; 3+ enterprise deploymentsend-to-end.
- Expert Python 3.11+, SQL; strong systems thinking and data modeling.
- RAG at scale: vector DBs (Pinecone/Weaviate/FAISS), BM25, rerankers, prompt/routing strategies, evals (faithfulness, coverage, latency).
- MLOps/SRE: versioning, canaries/A-B, drift detection, observability, cost/perf trade-offs.
- Clear communication; ability to turn messy, multilingual data into reliable software.
Nice-to-Have
- Knowledge graphs (Neo4j/RDF/SPARQL), schema alignment/ontologies.
- VL/Document AI (LayoutLMv3, Donut), CAD/vector parsing, safety/compliance domain exposure.
- Orchestration frameworks (Temporal/Argo), FastAPI,AWS EKS,PostgreSQL,Pinecone.
- LLM fine-tuning/LoRA, retrieval-graded generation, multi-agent planning.

Interview Process
passed the (initial) resume screening
- Technical Screen (45m):Your RAG decisions; live triage of a retrieval accuracy issue.
- System Design (2h):End-to-end design for a compliance-grade knowledge system (data → RAG → UI/UX).
- Take-Home (48h window):See “One Question to Answer” below.
- Founder Conversation:Vision/values alignment; references with prior enterprise clients.
One Question to Answer (Take-Home Challenge),
Challenge: Multi-language Safety Document RAG Prototype
Goal:
Dataset Provided:
- 50 safety incident reports(25 Korean, 25 English)
- 10 regulatory PDFs(5 Korean- KOSHA, 5 English- OSHA)
- 20 MSDS sheets(mixed languages)
- 10 sample querieswith expected answers
Deliverables (48h window):
- A running API (or CLI) that answers the 10 queries with citations
- Brief README covering: indexing strategy, retrieval pipeline (hybrid choices), chunking, reranking, bilingual handling, and evaluation method
- Report with metrics: answerability, faithfulness (citation match), and latency (p50/p95)
What we’re looking for:
 Sound architecture, multilingual retrieval quality, clean evidence chains, pragmatic cost/latency trade-offs, and a clear eval plan.
