In this role, you will own the AI layer of Zero Gravity Tutor, build adaptive systems, tackle complex AI problems, and design rigorous evaluations. You will also prototype new features, own the product roadmap, and act as the voice of the student and teacher. Additionally, you will work closely with partner schools and teachers, help define product packaging and positioning, and champion a culture of curiosity and learning.\nMissions\nPosséder la couche d'IA de Zero Gravity Tutor, y compris la stratégie de prompt, la sélection du modèle, l'architecture du contexte, la conception de la récupération et la qualité de la sortie.\nConstruire et itérer sur les systèmes qui rendent Zero Gravity Tutor véritablement adaptatif, en fournissant un coaching qui répond à la façon dont chaque élève pense, apprend et se prépare.\nS'attaquer aux problèmes difficiles de l'IA, en passant des sujets objectifs aux sujets subjectifs, en résolvant l'évaluation à grande échelle et en maintenant la qualité à mesure que le produit s'élargit.\nProfil recherché\nProven track record of building AI-powered products - not just bolting a chatbot on, but thinking hard about prompting architecture, model behaviour, and what genuinely good AI UX looks like\nTechnically hands-on: comfortable enough with code to prototype ideas, run evals, and debug model outputs using AI coding tools. You don't need to be a software engineer, but you should be able to move fast without waiting for one and move towards contributing to the codebase (Ruby, Rails, Javascript, Postgres, and AWS)\nDeep understanding of LLM fundamentals - context windows, RAG, prompt engineering, fine-tuning trade-offs, and how to measure model quality rigorously\nStrong product instinct with experience owning end-to-end product lifecycles - from discovery and definition through to delivery and iteration - across B2C and/or B2B contexts\nData-driven decision-maker: comfortable with analytics tools (e.g. Metabase, Mixpanel, Google Analytics) and able to define what success looks like before a single line of code is written\nExcellent communication and stakeholder management skills - able to align engineers, commercial teams, and a founder-CEO behind a clear product direction without a lot of process\nPassionate about impact: you care about outcomes, not outputs, and you want the product you build to genuinely change life chances\nNice to have:\nExperience in EdTech, consumer subscription apps, or B2B SaaS with an end-user product component\nFamiliarity with UK education - exam boards, curriculum structure, how schools buy and adopt software\nExperience taking a product from early traction to scale - you've navigated the messy middle and know what it takes\nHave worked alongside a Growth team and understand how product and growth interlock\nHave worked in a company at the 20-50 person stage, where everyone does more than their job title suggests","description_format":"text","description_chars":2974,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Higher Education"],"lifecycle":[{"event":"open","at":"2026-11-04T03:47:39Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"Licensed UK visa sponsor (Skilled Worker, Scale-up)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker;
