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).

What You’ll Do

  • Transform complex, manual permitting workflows into seamless, AI-enabled software experiences.

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

  • Partner cross-functionally with Operations, Customer Success, and Sales to deliver intelligent, user-facing features.

  • 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.

  • Help establish engineering best practices and contribute to a culture of technical excellence.

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

What We Offer

  • Competitive salary and meaningful equity in a high-growth company

  • Comprehensive medical, dental, and vision coverage

  • Flexible PTO and paid family leave

  • Home office & equipment stipend

  • Hybrid NYC office culture (3 days in-office/week) with direct access to leadership

  • In-Office Lunch & Dinner Provided
