AI Engineer

About LearnVector

For most of history, great teaching has been scarce. A brilliant teacher who knows you well, adapts to how you learn, and patiently stays with you until you get there — almost no one has had that. AI changes what's possible. LearnVector, founded by Andrew Ng, is building a trustworthy AI guide for learning, with a mission to accelerate human development. We're a small, fast-moving team working on-site in Mountain View, California and backed by a $100 million investment from Coursera.

About the role

The AI Engineer will build the agentic systems at the core of the product: systems that understand each learner, plan a path with them toward skills worth having, and work with them step by step until they get there.

This is not a wrap-an-API role. The hard problems are the ones frontier models don't solve on their own: maintaining an accurate picture of a learner over weeks and months, deciding what to teach next and when to hold back, keeping long-running conversations useful rather than merely pleasant, and verifying that generated teaching is correct before a learner ever sees it. You'll own systems end to end — design, implementation, evaluation, and iteration against real learner data.

What you will do

- 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?

What you bring

- 3+ years as a software engineer, with substantial hands-on experience building with LLM APIs (Claude, OpenAI, or similar): agentic workflows, tool use, structured output, long-context and memory patterns

- Experience shipping and operating LLM systems in production, including evaluating them - you have opinions about evals because you've built them

- Strong Python and/or TypeScript/Node engineering skills; comfort owning services end to end

- Ability to turn a fuzzy product question ("is the tutor actually helping?") into a measurable system, and ship without heavy oversight

Nice to haves

- Experience with conversational AI products, tutoring systems, or long-running assistant relationships

- Background in recommendation, personalization, or user-modeling systems

- Familiarity with the education or learning-science landscape

- Experience with voice interfaces or real-time interaction

What success looks like

In your first 30 days, you will have shipped a measurable improvement to the core tutoring loop and stood up an evaluation that tells us whether it worked. 

In your first 6 months, the agentic core — learner model, planning, verification — will be a durable system the whole product builds on, with quality metrics the team trusts and a cadence of improvement driven by real learner data.
