Fullstack Software Engineer

We are looking for a Full Stack Software Engineer with 0–4 years of experience to join Aristotle as a founding team member and build the future of AI-powered education. You'll be joining a team of 8 at an applied AI research lab that's building a voice agent tutor: combining LLMs, voice, vision, and memory to deliver personalized tutoring to students. We need someone with high agency, hacker energy, and a clear sense of where they want to go in their career.

What will you be doing?

• Build and scale real-time, multimodal tutoring experiences combining voice, vision, and memory systems*
• Experiment with LLM-centric harnesses and context-engineering to figure out how to get LLMs to teach well*
• Ship full-stack features end-to-end: backend-leaning work with front-end that can increasingly be AI-coded*
• Prototype and evaluate memory systems inspired by cognitive science and cutting-edge agent research*
• Collaborate closely with product and design to wrap complex multi-agent architecture in intuitive UI that students experience as simply being tutored*
