All positions, unless otherwise specified, can be performed remotely (within the US) regardless of any specified location above.</p> <h3>About the Job</h3> <p>The newly formed <strong>AI Growth Enablement</strong> team sits at the intersection of Product, Data Science, and Engineering. Our charter is to unlock step-function growth in users, subscribers, and revenue by building shared AI/ML capabilities — including but not limited to experimentation and automation tools, generative AI models, predictive-model APIs, and self-serve tooling—that accelerate decision-making, experimentation and automation across multiple product teams. You’ll partner closely with Data Scientists and other Cloud engineers in the Growth organization, as well as Data Analysis teams and mobile enigneers, to turn data and models into delightful, effective experiences at scale, and to empower each team to leverage AI/ML in the most effective way to drive user and revenue growth.</p> <p>Come join us as we build the infrastructure to handle our ever growing user base. We will continue to break down our monolith in favor of microservices that service our mobile clients today. You will be working alongside our Architecture and Product teams to move fast as we expand the business to build a recommendation engine that empowers rapid experimentation.</p> <p>Together, we will build systems that are strong and reliable to uphold a heavy load, yet malleable to fit many product demands. </p> <p>For candidates based in the US, the salary range for this position is $155,000 to $228,000 USD.
