As a Principal AI Engineer in the AI Incubator, you will be a force multiplier across product and engineering. You will bring strong systems thinking, fast execution, and high-quality craftsmanship to the challenge of delivering production-ready AI experiences that feel magical to educators and students. You will design and deliver production systems that make full use of large language models to power in-product assistance, summarization, personalization, and task automation. LLMs are a foundational part of our platform. You will be responsible for selecting the right models, structuring inputs and outputs, and building robust infrastructure that supports scalable and reliable usage in real-world settings. This is a role for someone who thrives in high-trust, high-autonomy environments. You will ship quickly, raise the bar for those around you, and turn early-stage ideas into durable systems that create measurable value for educators and students.
