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.

Together, you can build and host a full-stack web application - and all you need is a little Python. (Yes, even the client-side code - we compile Python to JS with a Pythonic GUI framework!)

We’re looking for an experienced all-rounder to work on the core Anvil platform, with a focus on the back-end. Our stack is mostly Clojure, Javascript, Python, Postgres, and container tools – but we're looking for someone who isn't afraid to jump into something you haven't used before.

You’ll be working with other seriously good all-rounders, including the founders (relevant PhDs, kernel contributors, built a dancing fountain for fun, that sort of thing) and senior colleagues (eg: Stu went from teaching Python in maths class to reverse-engineering our drag'n'drop editor in months), as well as our other developers and developer advocates. We're bootstrapped and profitable, with a small, smart, friendly and diverse team.

Building dev tools is great! We're solving problems we've experienced ourselves, our customers are developers just like us, and platforms have the most fun engineering problems.

For full job descriptions, and to hear what it's like working here, go to https://anvil.works/jobs.

We work hybrid (in the office Tue-Thu, wherever you like Mon/Fri). If you have questions, I'm a founder and my email's in my profile.
