At Posh, you'll help shape our platform that brings people together through live events. Your work will directly impact how event organizers create experiences and how attendees discover and enjoy them. We're looking for someone who excels in both technical skills and leadership. You'll tackle exciting projects that push our platform forward. Some recent work includes building a system for users to follow each other, creating curated event playlists, and tools for affiliate event promotion. If you enjoy solving real-world problems and working in a fast-paced environment, you'll fit right in. This is an in-person role based in our New York City office in the heart of SoHo. Building live experiences and building with soul are important for our customers, and we believe being and working together as a team is the best way for Posh to feel and achieve this.
