AI engineer in education technology

We are partnering with a category-leading online learning company that is rebuilding its product around AI-native, personalized tutoring. Following the acquisition of an AI-native learning startup, they are assembling a small, high-calibre AI engineering team to build two core systems from the ground up: an AI Tutor that delivers real-time, adaptive teaching (finally cracking one-to-one tutoring at scale), and an AI Creator that turns expert knowledge into high-quality, interactive learning content.

• The core agentic systems behind a real-time AI tutor and an AI content generator.
• Production LLM systems that are fast, reliable and cost-efficient, including the move from frontier models toward open-weight models without losing quality.
• The evaluation frameworks and human-in-the-loop quality controls that prove the product actually teaches.
• Design and ship agentic workflows in Python with LangGraph or LangChain, prompts and vector databases.
• Own systems end to end, from architecture through production, monitoring and iteration.
• Optimize for cost, latency and reliability at scale.
• Mentor a small team and shape zero-to-one product direction.

• A builder first: strong software-engineering foundations and a track record of shipping agentic AI systems to real users in production.
• Proven ability to operate at principal or staff level on complex production AI systems.
• Hands-on experience with model and cost optimization, and with evaluating output quality (golden sets, LLM-as-judge, user feedback).
• Genuine interest in education, or prior EdTech or AI-education product experience (especially for the Creator work).
• Будет плюсом: Background at a fast-moving startup (YC or similar) or as a founder; Experience fine-tuning or adapting open-weight models; Work on educational content quality or data-labeling pipelines

• up to 200,000 GBP base, plus equity and bonus
• Remote-friendly with occasional travel for collaboration. Permanent role, with visa sponsorship and relocation available for the right person.
