Full Job Description

Ello’s mission is to maximize the potential of every child, everywhere. To close that gap, we’re building the world’s first AI teacher: one that listens, speaks, adapts, and inspires, just like the best human educators.   Our first product, Read with Ello, has already helped hundreds of thousands of kids each week learn to read. It listens as they read aloud, offers support when they stumble, and generates magical, personalized stories. It works, and kids love it.   Now, we’re scaling that success into something even bigger: a complete AI teacher for all children. Our new app combines language, speech, and memory to deliver interactive learning for kids worldwide – check it out here https://new.ello.com/. We’re moving fast: we ship weekly, test directly with kids, and push the boundaries of what AI can do in education.   ABOUT THE ROLE We’re looking for an AI/ML Engineer to join our product engineering and applied research team. Our team operates at the intersection of research and production, solving open-ended problems while delivering real-world products. We use the best tool for the job, whether that’s a novel machine learning model or plain software engineering fundamentals. You’re excited to build an AI product that pushes the boundaries of what’s possible in education. You believe that great products and research strengthen each other. You’ll thrive here if you enjoy shipping AI features into a real product, designing the evaluations that prove they work, and turning fuzzy product questions into measurable experiments. You’ll make an edit in your Jupyter notebook this week, deploy it on-device next week, and watch it bring smiles to kids’ faces a day later. WHAT YOU’LL DO - Help define the impact of AI on children’s education. - Own AI systems and features end-to-end: from identifying product opportunities, to building and operating research and evaluation systems, to shipping production improvements used by children worldwide. - Collaborate with learning exp
