Job description

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.

As the U.S. enters a new capex supercycle across data centers, factories, housing, and renewables, joining PermitFlow means building the AI infrastructure at the core of every construction project driving the next wave of reindustrialization.

We’ve raised over $90M, most recently completing our Series B, (https://www.permitflow.com/blog/permitflow-series-b) from top-tier investors including Accel, Kleiner Perkins (https://www.linkedin.com/feed/update/urn:li:activity:7401703305569275904/), Initialized, Y Combinator, Felicis, and Altos Ventures, with backing from leaders at OpenAI, Google, Procore, ServiceTitan, Zillow, PlanGrid, and Uber.

Our HQ is in New York City with a hybrid schedule (3 in-office days per week). Preference for NYC-based candidates or those open to relocation.

What You’ll Do

• Full Stack Development: Architect, design, and implement robust and scalable full-stack solutions. Collaborate with cross-functional teams to gather requirements, understand user needs, and translate them into technical solutions
• Front End Development: Develop responsive and intuitive user interfaces using React and Typescript. Ensure a seamless and visually appealing user experience across various devices and platforms
• Back End Development: Build and optimize server-side components using Node.js. Work with databases, particularly Postgres, to design and implement efficient data storage and retrieval solutions
• System Architecture: Contribute to the overall architecture and design of the construction management platform. Make high-level decisions regarding technology choices, scalability, and system integrations
• Leadership and Mentorship: Conduct code reviews, enforce best practices, and contribute to the professional growth of the development team
• Collaboration: Collaborate with product managers, designers, and other stakeholders to ensure alignment between technical solutions and business objectives. Participate in agile development processes, including sprint planning, daily stand-ups, and retrospectives
• Continuous Learning: Stay updated on industry trends, emerging technologies, and best practices in full-stack development. Evaluate and recommend new tools and frameworks to enhance the platform's capabilities

What We're Looking For

• Extensive experience in professional fullstack development, ideally most of which you’ve spent in startups
• Extensive experience working within our tech stack, which is listed above
• You sweat the important details and strive for excellence in your work
• Experience owning technically challenging and demanding cross-functional projects
• A record of identifying valuable projects, communicating the strategy for them, and executing on them autonomously
• A customer-first mindset and an interest in talking with customers to make sure what we’re building is a polished product meets their needs
• Habit of introspection and understanding what’s helped you be successful in the past

What We Offer

• Competitive salary and meaningful equity in a high-growth company
• 100% company-paid base medical, dental, and vision coverage for employees + healthcare FSA
• 401(k) savings plan
• Unlimited PTO and paid family leave
