PermitFlow (YC W22) | Staff, Fullstack & Frontend Software Engineers | New York, NY | ONSITE | Full-time | https://permitflow.com

PermitFlow’s mission is to streamline and simplify construction permitting in the $1.6 trillion United States construction market. Our software reduces time to permit, supporting permitting end-to-end including permit research, application preparation, submission, and monitoring.

We’ve raised a $31m Series A led by Kleiner Perkins with participation from Initialized Capital, Y Combinator, Felicis Ventures, Altos Ventures, and the founders and executives from Zillow, PlanGrid, Thumbtack, Bluebeam, Uber, Procore, and more.

Permitting is a challenging yet interesting problem; thousands of municipalities across the United States have their own processes and requirements - many which are continually updating. Software, AI, and LLMs provide an exciting opportunity for us to reason at scale and distill a nuanced and localized permitting process into a standard and streamlined experience for our customers.

We're looking for customer-obsessed, ambitious, and hard-working teammates who are excited about solving a real-world problem with technology at its helm.

DevOps Engineer | Reingold | Alexandria, VA or Raleigh, NC| Hybrid (2 days a week at our VA office or 1 day a week at our NC office)

At Reingold, DevOps isn’t just a support function; it’s a key part of how we deliver high-quality solutions for our clients. You’ll use a code-first approach to define and automate infrastructure, working with cross-functional teams to build systems that are secure, scalable, and repeatable. You’ll also develop fast, reliable deployment workflows that let teams ship code with confidence—and the observability that helps them own it in production, spot issues early, and fix them fast.

We’re looking for someone early in their DevOps career with real-world experience and the confidence to work independently on core infrastructure tasks. You don’t need to be a domain expert yet, but you should be hungry to learn, comfortable navigating unfamiliar systems, and confident in your ability to figure things out.
