Senior Full Stack Web Developer
Location: Phoenix, AZ/Austin, TX
SiteOwl (https://siteowl.com/) is a B2B SaaS application that enables customers to design, install, and maintain physical security systems. We are a small, startup team of 15 that was recently acquired by the multinational company ASSA ABLOY. This means we offer the feel of a small team with the resources of a large company. Our primary customers are system integrators and corporate physical security teams. The best analogy for our product is Google Maps for physical security systems. System designers upload their real-world floor plans, then drag various types of pins representing cameras, card readers, alarms, or other devices onto the map and edit details about those devices. Technicians then use those designs to install or update the security system using our mobile apps in the field. Offline is a primary use case for our customers who use our mobile applications while at Wi-Fi and cellular-challenged locations.
What you will be doing:
We have recently completed a rebuild of our existing application with modern technologies. Using Typescript, React, MAUI, Capacitor, and Supabase, we have built a small, debt-free, AI-friendly codebase that runs across web, mobile, and the back end. This allows us to be agile and ship often. We have a long backlog of new features we plan to add to the application, including building AI agents that can help design physical security systems, project manage the installation of those systems, and keep up with the maintenance and compliance of those systems.
Key areas you will contribute to in the role include:
