Founding MEP Software Engineer.

Software Engineering & Dev Full-Time

Founding MEP Software Engineer: our view in 3 lines...

  • The Role:Founding role for a software engineer with MEP experience building an AI CAD tool for architects and engineers.
  • The Person:The person will build CAD content for electrical systems, HVAC systems, single-line diagrams, and pipes, help with customer onboardings, and shape product improvements.
  • Requirements:The ideal candidate has experience in MEP and experience in software engineering.

About the role

We are building the AI CAD tool for architects and engineers, starting with common MEP 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

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, and more). AI has done heavy-lifting with scoping the breadth of content needed, but we will need a MEP engineer to help translate this isn’t 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
  • Experience in software engineering
