AI Engineer

LearnVector, founded by Andrew Ng, is building a trustworthy AI guide for learning and seeks an AI Engineer to develop the agentic systems at the core of its product. The role involves building tutoring loops, learner models, evaluation harnesses, planning and memory systems, and verification layers, while owning systems from design through production iteration.

Responsibilities:

• Design and build the agentic core: multi-step tutoring loops, tool use, memory, and planning over long-horizon learner relationships
• Build the learner model — the evolving, evidence-backed representation of what each learner knows, wants, and responds to — and the systems that read and write it
• Build evaluation harnesses for conversational quality and teaching quality, and use them to drive iteration; define what "this session taught something" means operationally and measure it
• Design guardrails and verification layers so generated content and tutor claims meet a bar a trusted brand requires
• Work daily with the founding team, including Andrew, on the hardest product questions: what should an AI tutor do, and how do we know it's working?
