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.

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.

Role Overview

As a Platform Engineer, you’ll join our growing infrastructure team in building, scaling, and fine-tuning the systems that keep our services running smoothly. You’ll help architect the backbone of our platform, focusing on automation, reliability, and continuous improvement. While your primary responsibility will be infrastructure, coding and problem-solving across the stack are core parts of the role. As a fast-growing startup, we all roll up our sleeves where needed, so flexibility and a collaborative spirit are key.

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

• Develop and maintain automation through Infrastructure as Code and CI/CD pipelines.

• Monitor, optimize, and scale our cloud infrastructure for performance and reliability.

• Establish and enforce best practices for observability, logging, and alerting.

• Lead and participate in incident response, troubleshooting complex issues and driving postmortem learning and improvements.

• Collaborate across engineering teams to improve developer velocity while balancing reliability, security, and cost.

What We’re Looking For

• 5+ years of experience in Platform, Site Reliability, Infrastructure, or similar roles.

• Strong experience with containerization and orchestration (Docker, ECS, Kubernetes a plus).

• Expertise with CI/CD pipelines and modern infrastructure automation tools.

• Coding and scripting proficiency (Python, Go, Bash, etc.).

• Hands-on experience with cloud infrastructure (GCP preferred) and distributed systems.

• Familiarity with monitoring, observability, and incident management best practices.

• Comfortable working in a fast-paced startup environment, where adaptability and ownership are essential.

• 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
