## About the role

As a Founding Engineer, you will work directly with the founders on ambitious applied-AI and distributed-systems problems spanning multimodal reasoning, spatial intelligence, and the built world. You will help build BIM-native systems that understand plans, models, technical documents, regulations, and spatial relationships, and power autonomous agents that review, reason about, and coordinate complex development and construction projects.

## What they're looking for

- Has built and shipped technically ambitious products
- Wants to work across AI systems, backend infrastructure, product, and frontend when necessary
- Understands that reliability, traceability, and evaluation matter more than impressive demos
- Thinks carefully about concurrency, state, retries, idempotency, rate limits, and failure modes
- Is deeply curious about frontier multimodal and agentic architectures
- Can turn ambiguous, real-world workflows into clear technical systems
