About Doaz
Doaz is a hyper-growth startup on a mission to turn fragmented industrial knowledge into instant, actionable insight.

We build LLM- and Vision-AI solutions for construction, heavy industry, and finance leaders who must transform terabytes of drawings, specifications, and regulations into real-time decisions.
We’re expanding our GeoAI programs (including joint work with POSCO E&C) and launching drawing-change detection services that automatically compare plan versions, detect deltas, and explain design impacts.
Why You’ll Love Working Here
• True 0-to-1 ownership — Ship models that land in production sites within weeks.
• Global impact, lean crew — 30 teammates across KR/PK/IN; no bureaucracy, only builders.
• Tech freedom — YOLO or RT-DETR?

Gemma-VL, Qwen-VL, or LLaVA?

You choose, we fund.
Role Overview
We’re hiring a Senior Computer Vision & Multimodal LLM Engineer (GeoAI & Drawing Change Analysis).
You’ll lead end-to-end development of a version-aware drawing-diff engine (PDF/DWG raster & vector), symbol/text extraction, and change-impact narratives powered by RAG/LLM.

Expect fast cycles from prototype → service: detection models, OCR/layout understanding, retrieval, and explainable outputs that engineers can trust.
Key Responsibilities
Drawing Change Analysis (CV)
Build a robust diff pipeline for architectural/structural/MEP drawings: rasterization, layer parsing, vector geometry ops, and semantic change clustering.
Train/finetune detectors & segmenters (e.g., YOLOv8/RT-DETR/Detectron2/SAM) for symbols (columns, openings, sleeves), title blocks, and revision clouds; achieve production-grade mAP/F1.
Implement geometry-aware post-processing (IoU/topology checks, snapping, graph connectivity) to reduce false positives.
Document & Layout Understanding
Engineer OCR + layout models (PaddleOCR/Tesseract + DocFormer/LayoutLMv3/Donut) to read legends, notes, schedules, and BOM tables; normalize to structured JSON.
Build version-aware entity tracking (IDs, gridlines, BH IDs, coordinates) across revisions.
GeoAI & LLM/RAG
Design retrieval over drawings/specs (BM25 + vector) with reranking; ground LLM answers in evidence with citations and clickable locations.
Generate change-impact summaries (e.g., slab shear reinforcement, opening proximity to columns) with rules + LLM verification; measure factual precision.
Productization & DevOps
Ship FastAPI/gRPC microservices, batch & streaming workers (Ray/Celery), GPU inference (Triton/TensorRT), and observability (Prometheus/Grafana).
Own evaluation: dataset curation, data labeling guidelines, ablation/A-B tests, and regression suites.
Collaboration
Work closely with domain SMEs (geotech/structural) to encode rules (KDS/KBC, internal standards) and prioritize what matters to the field.
Minimum Qualifications
5+ years of production Python (3.x) building ML-heavy backends; strong PyTorch.
3+ years in computer vision for detection/segmentation/OCR or document AI at scale.
Hands-on with multimodal LLM/RAG (LangChain/LlamaIndex), vector DBs (Pinecone/Weaviate/FAISS), and rerankers.
Proven experience parsing engineering drawings or complex PDFs (vector/raster), including geometry and layout reasoning.
Solid MLOps: reproducible training, CI/CD, model packaging, monitoring; cloud on AWS/GCP.
Fluent written & spoken English (Korean a plus).
Preferred Extras
GPU orchestration (Kubernetes/Ray/Slurm), high-performance inference (ONNX/TensorRT).
Experience with VLMs (Gemma-VL, Qwen-VL, LLaVA), CLIP, or doc-layout models.
Open-source contributions, papers, or strong public demos in CV/doc AI/RAG.
Full-stack chops (TypeScript/Next.js/React) for quick operator tools and review UIs.
Compensation & Benefits
Competitive base salary (market-leading) , around 20 lakh (yearly)
Performance-based annual bonus (up to 20%).
cloud credits, and AI tools support.
Hiring Process (≈ 2–3 weeks)
Quick intro call (15 min, mutual fit).
48-hour take-home: Drawing Diff + Evidence-Grounded Summary (provide code + short README; clarity > polish).
Deep-dive tech interview: architecture, modeling choices, evaluation, and scaling plan.
Culture & vision chat with Founder/CEO.
Offer — if all green, written offer within 24 h.
How to Apply
Email doaz@doaz.ai with subject [CV/LLM Engineer – Your Name] and include:
Résumé/CV with measurable outcomes (metrics, latency, cost, accuracy).
Current or recent salary.
GitHub and/or live demos of CV/doc-AI/RAG work (links preferred).
A one-page diagram of your “Drawing Revision → Detection → Evidence → LLM Narrative” pipeline, noting models, retrieval, and evaluation metrics.
Employment type: Full-time
Ready to turn messy drawings and specs into instant, trusted intelligence?
Let’s build the future together at Doaz.
