Software Engineer: Build the World’s Best AI Plan Checker
InspectMind AI • San Francisco • Full-time
$120K – $220K + Equity
The Mission
Every building is designed using drawings that often contain hundreds of mistakes.
These mistakes lead to costly delays, rework, and sometimes unsafe structures.
We’re building the AI Plan Checker — a system that reviews full construction plan sets (drawings, specs, calculations) in PDFs and finds issues before anything gets built.
Our goal is simple: every construction project in the world gets checked by AI before permitting and construction. Faster approvals. Fewer mistakes. Safer buildings.
Traction
• 100%+ month-over-month growth
• Hundreds of paying customers
• Thousands of projects processed
• Engineers finding hundreds of real issues per project
• Fully self-serve product
This is already being used in real workflows. So far, InspectMind AI has been used to check drawings across projects in data centers, universities and K–12 schools, hospitals and clinics, large multifamily and senior housing, energy infrastructure (battery storage, utility terminals), commercial spaces, and more, supporting architects, engineers, contractors, owners and developers across the US, Canada, Europe, South America, and Asia.
The Problem
Our AI can already find a lot of issues.
Now we’re focused on what matters most:
• Turning thousands of raw issues into clear, high-signal insights
• Reducing false positives and noise
• Making results trustworthy and actionable
• Driving repeat usage and team adoption
This is a hard technical problem across computer vision, AI agents design, and system design.
What You’ll Do
• Build core product features end-to-end (frontend, backend, AI)
• Improve accuracy and signal-to-noise of results
• Work directly with users (engineers, architects, contractors, developers)
• Own major parts of the product from idea to production
• Ship fast and see immediate real-world impact
What We’re Looking For
• 2–5+ years of experience shipping production code
• Our product is built entirely by AI. You need to use coding agents like Claude Code and Codex effectively to ship quickly while maintaining code quality and security.
• High velocity and strong ownership
• Strong intrinsic motivation to learn and grow
• Good product instincts and user empathy
• Excited by ambiguity and hard problems
Tech stack
AWS + NextJS
Why This Is Special
Your work will directly impact real buildings and real safety. If we succeed, every construction project globally will run through systems you helped build.
Team
• Ex-Google, Airbnb, Berkeley, CMU
• Former founders and early engineers
• YC W24, AI Grant, top VCs
Small team, high ownership, fast execution.
How We Work
• Fast-moving, product-focused
• Direct access to users
• No bureaucracy
Interview Process
• Intro call
• Technical interviews
• Trial project
• Offer

If you want to build something that matters and push AI into the real world, we’d love to talk.
