About the role
We are building the AI CAD tool for architects and engineers, starting with common MEP/data center workflows
About Us
- William and Brian met at Carnegie Mellon
- William worked at Meta and built homes in Texas
- Brian ran Rent the Backyard (YC S19), a housing factory in Oakland, CA
- William and Brian worked on their own CAD tools independently
- William and Brian met back up and started working together
- William and Brian took a small detour building AI on top of other CAD tools to go to market faster
- William and Brian realized with Claude Code it is now possible to build a better CAD engine and get to market
- William and Brian took their learnings and market demand and set out to build a better CAD engine from scratch to aid the whole market, starting with MEP/data center use cases.
Our CAD Tool
Our CAD tool differentiates with a few core feature sets:
- Web-first: heavy computation happens server-side
- Code-first: every component is defined via code. The biggest benefit to code-first is that AI is really good at reasoning over code. If you turn CAD into code, LLMs can do amazing things.
- Parallelization: cloud-first enables us to spin up agents to test stuff and return completed work back to the main plan
The end state for a user: tell the AI what you want, the AI encodes all your business rules & logic down to the component level in deterministic logic, sends a swarm of agents off to test work, then returns a finished, tested plan back to the user.
Why Join the ArchiLabs Team
- You are excited about the physical world and where software and the real world meet
- You are excited about unlocking productivity gains across homebuilding, industrials, and more
- FUN! The work is fun and the people are (hopefully in your eyes) fun!
The Role
We are looking for a founding MEP software engineer.
The founding MEP software engineer role will evolve, but there are a few core areas the person will contribute:
- Content: As part of building a CAD tool, we need content on top of the core engine (electrical systems, hvac systems, single-line diagrams, pipes, cooling systems, cabling, and more). AI has done heavy-lifting with scoping the breadth of content needed, but we will need a MEP/data center engineer to help translate this into acceptance criteria and QA/QC the work AI outputs.
- Forward Deployed Engineering: We expect many engagements to be white glove onboardings. We expect this founding MEP software engineer role to help with these onboardings and to be customer-facing.
- PM: We expect this MEP software engineer to be thoughtful about the future of CAD and where our tool needs improvements to meet market needs.
Skillsets/Experience we are looking for:
- Experience in MEP
