? We're hiring: AI Engineer — BuildSense AI (Gurugram)
We're building PropOS — India's first AI Operating System for real estate developers. Six WhatsApp-native AI agents, built for how Indian real estate actually works: in Hinglish, on WhatsApp, at the speed brokers expect.
Our first agent, replies instantly — availability, pricing, site visits — no human needed. We're demoing it live at BuildTek CORE Summit, Pune, on July 11th.
We just opened up our AI Engineer role and we're looking for someone to own it from day one.
What you'll own:
- Architecture for our AI agent stack (LangGraph-based, multi-agent system)
- Hinglish intent classification — going from prototype to production-grade accuracy
- Technical mentorship for a sharp, rapid-moving AI engineering team
- The judgment calls that turn a good demo into a product real estate developers trust enough to pay for
What we're looking for:
- Strong hands-on 4-5 years experience building production LLM/AI systems — not just prototypes
- Comfort owning architecture decisions end-to-end,
with the confidence to push back when something's wrong
- Genuine excitement about solving a real, underserved problem — not just chasing the AI buzzword
- Founder mentality: you'll be employee #6, building something from near-zero.
What You Will Do
Technical Architecture — You Own This Completely
• Design the multi-agent orchestration layer: choose and implement the right framework (LangChain, LangGraph, AutoGen, or CrewAI) for PropOS's specific agent coordination requirements. This is the most critical architectural decision of the company's first year.
• Build the WhatsApp-first delivery layer: integrate Meta WhatsApp Business API via a BSP partner (Gupshup or Kaleyra), handle multi-turn conversation state, manage session windows, implement media handling, and build robust fallback flows for API failures.
• Design the shared data ontology: model the PropOS unified data layer: Land Parcel → Approvals → Units → Bookings → Col
