We are the maintainers of several open-source projects in the Kubernetes space: 1. vcluster - Virtual Kubernetes Clusters: vcluster.com (certified Kubernetes distribution) 2. DevSpace - Docker-Compose But For Kubernetes: devspace.sh 3. kiosk - Multi-Tenancy Extension for Kubernetes: kiosk.sh (AWS security best practice for EKS) 4. jsPolicy - Kubernetes Policies using JavaScript & TypeScript: jspolicy.com Our commercial product is called Loft (loft.sh) and brings all our open-source projects together in one platform which enables high-velocity engineering teams to move faster when building cloud-native software. Most of our customers are startup unicorns and Fortune 500 companies.

Code for America is committed to building a team as diverse as the nation we serve. We’re made up of people-centered problem solvers: technologists, advocates, storytellers, and organizers from many different backgrounds and communities around the country. We merge the best parts of technology, nonprofit, and government. We believe government at all levels can and should work well for everyone— and the mindful use of technology makes it possible. We’re known for building digital tools, but the work doesn’t stop there. We seek to transform government by showing what’s possible when communities are included in policy and service design. We use insights and ideas from real people to guide us to real solutions that break down barriers to meet community needs and improve government in meaningful ways. Want to use your skills for good and help us drive change that lasts? Join our team!

Firecrawl is the easiest way to turn the web into data AI agents can use. One API call converts any URL into clean, LLM-ready markdown or structured data - the boring-hard problem everyone building with LLMs eventually hits, solved. We hit 8 figures in ARR in year one and more than doubled it in year two. We have 150k+ GitHub stars, and developers, agents, and category-defining AI companies build on us every day. Growth like this is rare, and we're just getting started. We're a small team punching far above our weight. Everyone here owns a real piece of the product and company, end to end, and runs it themselves - no hiding behind process or headcount. This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on, not one bolting AI onto an existing product. We move fast, go deep, and are building the tools superintelligence will rely on to gather data from the web.
