About the role
Our mission at Ello is simple and urgent: maximize the potential of every child, everywhere. We're building the world's first AI teacher to close that gap: one that listens, speaks, adapts, and inspires, just like the best human educators. Our first product, Read with Ello, is already helping tens 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 that can help children learn far beyond reading, including math and language learning. Our new app combines language, speech, and memory to deliver interactive learning for kids worldwide; check it out here . We're moving fast: we ship weekly, test directly with kids, and push the boundaries of what’s possible with AI in education. With the resources of the world's top investors and the heart of a public benefit corporation, we're here to revolutionize how children learn globally. Featured on TIME's Best Inventions and Fortune's Change the World, Ello is a small, mission-driven team taking on one of the most important challenges of our time: to democratize education.
About
the Role Ello is seeking a full-time AI Learning Designer (Math) to help shape the instructional vision and design of our math learning experiences. This role sits at the intersection of elementary math pedagogy and AI: you'll build and refine AI-powered math learning activities, steer our AI tutor to teach math the way a great human educator would, and work shoulder-to-shoulder with engineers to make it happen. This role is ideal for an AI-forward math educator or curriculum designer who can think both instructionally, creatively, and technically—someone who can define what learners need to learn, imagine how that learning can come to life within an AI-powered digital product, and collaborate deeply with engineers to build the future of educational technology. Because this role sits at the intersection of curriculum and technology, we’re looking for someone with a strong technical foundation. That might come from a background in computer science, AI, computational thinking, educational technology, or extensive experience building AI-enabled products and workflows. You don’t need to be a software engineer, but you should be excited to work closely with engineers, understand the capabilities and limitations of modern AI systems, and have a strong conceptual understanding of how AI components and software systems work together to deliver intelligent, interactive learning experiences. You’ll collaborate closely with curriculum, product, engineering, and design to shape Ello’s elementary math curriculum, develop engaging learning experiences, and ensure our math instruction is grounded in both learning science and exceptional product design. We're aiming to significantly grow our library of math activities this year, and we need someone who can ramp up quickly and hit that pace independently. This role is open as either a full-time contractor (SF preferred but open to remote candidates) or a full-time employee based in San Francisco. We're moving fast to fill it, but for the right person, we see this as a long-term seat on the learning design team. What You’ll Do Design and build AI-powered math lessons that combine strong pedagogy with engaging learner experiences. Evaluate AI tutor outputs to ensure they are instructionally effective and developmentally appropriate. Guide and refine AI tutor behavior by helping shape prompts so the agent teaches as an expert math tutor would. Collaborate with engineers and AI researchers to continuously improve the quality of AI-driven instruction through testing, iteration, and evaluation. Key
