About Genius AI Genius AI is building technology to help local businesses run themselves. Genius AI products do the admin work that keeps practitioners from the work they love and the people they serve. From GlossGenius to Reception, its products work 24/7 on busywork like booking, marketing, client management, finances, staff and inventory management, and more. Genius AI technology has saved businesses 106M in admin hours, earned them $2.0B in additional revenue, and facilitated more than 624M client touch points. About the Role Genius AI is building 0-to-1 AI products we expect to be a massive revenue driver, and this role sits at the center of that build. As a Staff Backend Engineer, you'll be the technical anchor for our highest-innovation teams: setting architectural direction, validating options through proof-of-concepts, and turning ambitious initiatives into clear, buildable roadmaps. This is an IC role with real leadership weight, roughly 60% architecture, planning, and technical direction, 40% hands-on building. The person in this role will be a force multiplier: unblocking engineers before they know they're stuck, making the hardest technical calls so the team doesn't lose momentum, and setting a new standard for what great backend engineering looks like at Genius AI. You won't be maintaining systems someone else designed, you'll be raising the ceiling on what this team can build, and doing it in a way that makes everyone around you better in the process. You must be commutable to our NYC headquarters and will operate in a hybrid environment. We default to being in-office 3–4 days per week with required attendance on Tuesdays and Thursdays.
