Founding Tech Engineer – Full Stack + AI/ML (Revit / AEC Software) 📍 In-office role | Chennai, India | Full-time About Us We are a US-based AI startup in the AEC (Architecture, Engineering & Construction) industry , building the first-ever AI product to revolutionize architectural detailing — one of the biggest time drains in architecture and engineering. Architects spend 60% of their time on detailing (wall sections, foundation drawings, construction documents) instead of design. Our product automates this, saving firms 30% of overall salaries and dramatically improving timelines. We are working at the intersection of: AI/ML, Generative AI, RAG (Retrieval-Augmented Generation), LLM applications BIM (Building Information Modeling), Revit, AutoCAD, Dynamo, Autodesk Construction Cloud SaaS, Cloud Infrastructure, and Modern Full-Stack Development We’re backed by an ex-McKinsey founder with deep AEC expertise and already validated by 50+ architects , with pilot users onboard. Our vision is to build the go-to AI software stack for the $50B+ AEC software market. Responsibilities Build and maintain scalable full-stack applications (frontend + backend) to power our AI product. Design, develop, and deploy AI-powered tools : RAG systems, LLM-based automation, recommender engines. Work directly with the Revit API, AutoCAD, Dynamo, BIM 360, and Forge/Autodesk Construction Cloud to create plugins and integrations. Implement and optimize vector search, embeddings, semantic search for architectural detail retrieval. Collaborate closely with founders, architects, and engineers to ship MVP features fast and iterate. Set up scalable infrastructure with AWS / GCP / Azure, Docker, Kubernetes, CI/CD pipelines. Ensure robust system design balancing speed-to-market with future scalability. Requirements Must Have: 5+ years of startup experience (fast shipping, small teams). Strong background in AI/ML : RAG, LLMs, NLP, embeddings, recommender systems. Experience with Revit/AutoCADD APIs, Revit plugins , or strong interest in BIM/AEC tech. Proven ability to ship end-to-end solutions independently. Technical Stack (experience in some/all): Programming Languages: Python, JavaScript, TypeScript, C#, .NET Frameworks: React, Node.js, FastAPI, Flask, Django Databases: PostgreSQL, MongoDB, Redis, ElasticSearch, Pinecone AI/ML Tools: LangChain, HuggingFace, OpenAI APIs, TensorFlow, PyTorch Cloud/DevOps: AWS (Lambda, S3, EC2), GCP, Azure, Docker, Kubernetes, CI/CD Why Join Us Better than industry compensation + ESOP/Equity (founding team upside). Opportunity to work on massive whitespace + technical greenfield problems. Exposure to the rare intersection of AI + AEC (Architecture, Engineering & Construction) . Fast-track growth: from early engineer → core product leader. Be part of a founding team , influencing product, culture, and strategy from Day 1. Work Setup 📍 In-office role in Chennai, India (startup culture, high-collaboration environment). 🌍 Working closely with global architecture and engineering firms in the US. 💡 If you’re a full-stack developer who thrives in startups, loves AI/ML, and is excited by AEC software — this is the role where you’ll build something that redefines an industry.
