TaxJar is the leading technology solution for busy eCommerce sellers to manage sales tax and is trusted by more than 10,000 businesses and developers. We were founded to help eCommerce merchants spend less time on sales tax and more time growing the businesses they love. We're passionate about creating simple solutions and leveraging technology to solve complicated sales tax issues. We're a lean distributed team that knows first-hand the sales tax challenges we're working to resolve. We're lean, but experienced. We've started our own businesses, sold successful companies (a few in the tax and accounting space), been part of IPO's, worked at fortune 500s and have even resold hundreds of designer shoes on eBay from the garage. We get it. Sales tax isn't fun and that's why we made TaxJar. We all work remotely from wherever we work best for each team member. For most of us, that's home. For others, that may be a local coffee shop or a summer vacation house. The only requirement is that we're working from a place with WiFi, and we're able to get our work done. We talk all day over Flowdock and each of our teams have separate rooms to discuss what's necessary. We're a happy TaxJar team and we all really love what we do. We've created a space where high-achievers can succeed, but are also safe to fail. We're profitable and focused on growing TaxJar sustainably. We're always learning how to make TaxJar the best place to work for all of us, and not just another tech start-up. We're always looking for an amazing new teammates to come share in the excitement of solving real-world problems with technology.... and we're hiring!
