Job Description: About ArcwayArcway is an architectural design tool where buyers can design and walk through a photoreal home instantly in their browser. Homebuilders use Arcway to close faster and sell more homes. We’re a small team of ex-architects and product builders from Figma, Coinbase, Xsolla and Modern Health. We’re backed by Indie, Ritual, Soleio, Jorn + Koen, and other top angels.Role & ResponsibilitiesArcway ingests unstructured design files, and turns them into production-ready 3D homes. Today this process is slow, error-prone, and requires architectural intuition to resolve contradictions, missing details, and layout issues. You will design ML systems that eliminate these bottlenecks.You will also help automate home staging (e.g. faucets, lighting fixtures): matching SKU data we receive from a customer to create performant, game-ready 3D assets from our internal library, manufacturer datasets, or generative pipelines.Convert unstructured design files into accurate 3D geometry data.Turn product references into usable 3D assets.Optimize 3D assets using ML/GenAI.Build end-to-end ML pipelines that ingest, parse, extract, validate, and output structured JSON.Create feedback loops where human corrections feed into a retraining cycle.Tools & LanguagesCore ML / AI ToolingPythonPyTorch (or TensorFlow/JAX) for training and running modelsTransformer models for multimodal document understanding, for example LayoutLMv3Vision models for recognizing floor plans, symbols, and annotations, for example Detectron2Diffusion or generative models for simple shape completion or reconstructionGeometry, CAD, and Floor-Plan UnderstandingCAD parsing experience using libraries such as ifcopenshellKnowledge of geometric primitives, 2D to 3D inference, and computational geometry using tools such as Open3DExperience extracting symbols and room features from PDFs or images with OpenCVDocument Parsing and Structured Data ExtractionOCR and layout extraction using tools such as TesseractEmbedding and similarity search systems such as FAISS for asset lookupWe're Looking ForPeople that want to work closely with co-founders at a fast-paced startupStrong communication skills, we expect you to be able to deeply describe a technical problem you worked on in layman's termsDeeply care about data quality and consistencyComfortable working with highly variable builder documents that contain contradictions or missing informationBonus (not required)Interest in 3D generative AI, for example Meshy or TripoSRExperience generating synthetic data for indoor layoutsPersonal interest in architecture, BIM, or CAD systemsWhat We OfferBe an early hire building the backbone of a fast-growing AI company.Influence how data, AI and 3D design intersect in the built world.Awesome benefits: https://golden-magnolia-e09.notion.site/Arcway-Employee-Benefits-27ab7624659980daa022febd0c4cb495?pvs=74.Competitive salary, meaningful equity, and hybrid flexibility.
