Founding Engineer - Full Stack

About Muro AI

Muro AI is transforming how the $2T construction industry plans and builds. Founded by Cornell alumni, ex-founders, and former McKinsey operators, we’re building AI agents that automate the most complex, manual, and costly phase of construction: preconstruction.

We move fast, build with conviction, and obsess over delivering real impact to the people who build our world. If you want to shape how the next century of construction gets built, this is where it starts.

Who You Are

A true builder with 4+ years of technical experience. You’ve lived the 0→1 chaos — maybe you co-founded something, or led a team through the trenches. You know that the good (fast growth) and the ugly (2 AM patches) come with the territory. You’re scrappy, curious, and energized by uncharted problems.

Why It Matters

• Shape a category. No one owns “pre-con AI” yet — we’re charting that map.

• Bridge two worlds. We’re redefining how construction tech meets AI — your work will connect human workflows with intelligent systems at scale.

• Drive impact. Your platform will help contractors close multi-million-dollar bids and save hundreds of hours per project.

Your Mission

• Own the platform end-to-end. Design and build the core Node.js/TypeScript services that the entire application runs on.

• Architect for scale and flexibility. Build service boundaries that make sense. Know when to go monolith vs. microservices. Create data models that handle construction’s complexity without becoming a mess. Make the hard calls on build vs. buy vs. open source.

• Ship the desktop app. Lead development of our Electron app for Mac/Windows. Handle offline sync, file system access, and automatic updates. Make it feel native and bulletproof.

• Build for enterprise from day one. Design multi-tenant architecture that can also go single-tenant. Build the auth system, permissions, and team management.

• Create the integration backbone. Build the framework that connects to Procore, SharePoint, and Excel. Design async job systems for long-running processes. Create webhook infrastructure, retry logic, and sync engines. Make integrations that don’t break when APIs change.

• Operate what you build. Own monitoring, logging, and alerting. Set up CI/CD to ship daily. Design backup and disaster recovery systems.

Tech Stack

• Backend: Node.js, TypeScript, Express, PostgreSQL

• Frontend: React, Electron, Redux/Zustand

• Infrastructure: GCP (Cloud Run, Cloud SQL, Pub/Sub), Docker, Supabase

• DevOps: GitHub Actions, Sentry, Posthog

• Integrations: REST/GraphQL APIs, Webhooks, OAuth flows, Queue systems

Who Should Apply

We’re looking for a senior engineer with 4+ years of experience building and scaling B2B platforms.

You might be:

• A Senior Full-Stack Engineer who’s been the technical anchor of a startup

• A Founding Engineer who built the platform others relied on

• A Tech Lead who still codes 70% of the time

• A Staff Engineer at a larger company ready to own everything

You'll Stand Out If You Have

• Scaled an app from zero to real customers

• Built Electron apps that didn’t suck

• Integrated complex file sync systems

• Experience with construction tech (Procore, Autodesk, etc.)

• Built SaaS desktop apps with enterprise features

Real Talk

• You’ll context switch between React components and database indexes daily.

• When enterprise customers ask “but is it secure?” — that’s on you.

• If you love clean code, stable systems, and making other engineers productive, you’ll thrive.
