Staff Software Engineer, Backend

As our Staff Software Engineer on the Guides & Surveys team you will help our customers guide, survey, and engage their users in real time, inside their own websites and apps. Guides & Surveys is one of Fullstory's fastest-growing products and you'll be one of the key engineers behind it. Every day you will work across the full system your team owns, from infrastructure and back-end services to the JavaScript that runs on customers' sites, turning ambiguous product ideas into designs that ship. You'll own the service that stores user progress, guides, and survey data, keeping it reliable across devices, and you'll lead its next chapter as we bring it onto Fullstory's core technology stack. This is a full-time employment opportunity facilitated via our Employer of Record (EOR), Rippling. Your local employment- payroll, benefits, and compliance, will be administered by Rippling in accordance to the local labor laws in your country. This role can be performed remotely anywhere within Bogotá, Colombia.
