Senior Backend Engineer, Data Platform

Who we are:

Stay Ai is powered by savvy DTC industry vets, who have each been building subscription programs for over ten years. We’ve worked with over 300+ subscription-focused CPG brands that have generated hundreds of millions in subscription revenue alone. Our product is shaped by lifelong marketers who specialize in acquisition and retention, not developers—and it shows.

We have amazing investors like Telescope Partners, with participation from Boulder Food Group, Riverpark Ventures, and Vanterra Capital. Previous investments were led by Watchfire Ventures, alongside industry leaders such as Nik Sharma (Sharma Brands) and Adam Turner (Postscript).

We are not afraid of challenging work and are excited to build the next big thing. Sound good to you? Then, please read more about our role!

Our culture:

We are dedicated to our work, but equally committed to celebrating our achievements. Collaboration is at the heart of everything we do, as we firmly believe in the power of teamwork. While we are remote-first as a company, we try to create opportunities to meet each other. That’s why we organize annual offsite retreats in beautiful Park City, Utah, where we engage in exciting activities such as tubing, ATV rides, and hiking adventures!
