Fullstack Software Engineer

PermitFlow is redefining how America builds. We’re an applied AI company serving the nation’s builders, tackling one of the largest information challenges in the economy: understanding what can be built, where, and how . Our AI agent workforce helps the fastest-growing construction companies navigate everything from permitting and licensing to inspections and project closeouts – accelerating housing, clean-energy, and infrastructure development across the country.

Despite being a $1.6T industry, construction still suffers from massive delays, wasted capital, and lost opportunity. PermitFlow has already delivered unprecedented speed, accuracy, and visibility to over $20B in development, helping contractors reduce compliance time, de-risk projects, and scale with confidence.

America is entering a CAPEX super-cycle, from data centers and factories to housing and renewables, and joining PermitFlow is building the AI at the heart of every construction project powering the next wave of re-industrialization.

We’ve raised over $90M, most recently completing our Series B, from top-tier investors including Accel, Kleiner Perkins , Initialized, Y Combinator, Felicis, and Altos Ventures, with backing from leaders at OpenAI, Google, Procore, ServiceTitan, Zillow, PlanGrid, and Uber.

This role requires a hybrid schedule (3 in-office days per week).

• Design and implement backend and frontend services, APIs, and data pipelines to support AI-driven workflows.

• Work directly with users to shape product direction and rapidly ship features that drive impact.

• Own features end-to-end, from architecture and implementation to testing and production deployment.

What We’re Looking For

• Strong experience in fullstack development, ideally including time at a startup or fast-moving team

• Comfortable owning features across frontend, backend, and data layers

• Experience with React, TypeScript, Node.js, and Postgres, or ability to learn quickly

• Track record of shipping production systems and making thoughtful trade-offs for speed, reliability, and scalability

• Excitement for AI-powered tools that solve real-world construction challenges and a customer-first mindset
