Ph3Co-Founder CTO — AI-First Consumer EdTech /h3 pWe’re building a new kind of student advisor: an AI-powered, research-driven product that helps teens and young adults discover careers, choose study paths, and take confident next steps. Today, millions of students face noisy advice, fragmented resources, and decisions made with guesswork. We believe orientation should be evidence-based, personalized, and accessible to anyone. We’re early, shipping fast from Alicante, Spain. We’re open to hybrid or remote and are willing to relocate/switch locations for the right build context. /p h3The Role /h3 pYou’ll be the technical co-founder owning product architecture and velocity: /p ul liLead end-to-end tech strategy: data, AI, APIs, security, cloud. /li liTurn research and user interviews into shippable product (MVP → v1 → scale). /li liBuild core services: assessments, recommendation engine, narrative generation, student profiles, progress outcomes tracking. /li liStand up clean, testable code and lean infra that’s cheap to run and easy to iterate. /li liRecruit and mentor a small, exceptional product/engineering team. /li ul h3What You’ll Work On (first 90–120 days) /h3 ul liStand up a thin vertical slice: onboarding → assessment → results → “what to do next”. /li liDesign the data model for students, assessments, skills, and career paths. /li liPrototype and evaluate AI components (retrieval, scoring, narrative generation, guardrails). /li liInstrument analytics and run experiments to validate activation, retention, and learning impact. /li liShip weekly: ship iterate measure. /li /ul h3Our Product Focus /h3 ul liEducation, not content: decisions, outcomes, and repeatable guidance. /li liAI + research: blend LLMs with validated frameworks (aptitudes, learning styles, job market signals). /li liConsumer-grade UX: simple, credible, and motivating for students and families. /li /ul h3You Might Be a Fit If You /h3 ul liHave built and shipped consumer products end-to-end (0→1 and 1→n). /li liAre comfortable owning full-stack: from schema design and APIs to frontend polish. /li liCare about measurement, experiment design, and product truth over opinions. /li liHave practical experience with LLMs and retrieval (prompting, evaluation, safety, costs). /li liCommunicate clearly, move fast, and enjoy building with customers. /li /ul h3Helpful Experience (Nice to Have) /h3 ul liPrevious founder or early-stage CTO/Head of Engineering experience — ideally having taken a product from 0→1 and beyond. /li liShipped consumer-facing products with strong adoption, ideally in EdTech, AI, or other recommendation-heavy verticals. /li liDeep knowledge of AI/ML trends — LLMs, recommendation systems, embeddings, vector databases, evaluation frameworks, and cost-optimization strategies. Strong grounding in data architecture and security for consumer products: user privacy, consent, GDPR compliance, and scalable infra. /li liTrack record of hiring, leading, and mentoring engineers, building a small but world-class team. /li liExperience running fast product experiments: A/B testing, feature flags, instrumentation, and metrics-driven iteration. /li liExposure to fundraising conversations or tech diligence processes is a plus (communicating technical vision to investors). /li liIndicative Stack Technical Scope (Flexible) We’re not tied to one stack, but expect you to design and own the right setup for speed, cost-efficiency, and scalability. Familiarity with some of the following is valuable: /li liLanguages Frameworks: Python (FastAPI, Django, Flask), TypeScript/Node.js, or Go for performance-critical services. /li liAI/ML Ecosystem: LLM orchestration (LangChain, LlamaIndex, Haystack), model fine-tuning, open-source models (Hugging Face, Mistral, Llama), vector DBs (Pinecone, Weaviate, Milvus), retrieval-augmented generation, evaluation harnesses. /li liData Infra: Postgres, scalable cloud DBs, event streaming (Kafka, Pub/Sub), containerization (Docker, Kubernetes), and cloud providers (AWS/GCP/Azure). /li liFrontend User Experience: React/Next.js, mobile (React Native/Flutter) — ensuring consumer-grade simplicity and delight. /li liDevOps Reliability: CI/CD pipelines, testing frameworks, monitoring (Datadog, Prometheus, Sentry), and cloud cost control. /li liExperimentation Growth: Analytics (PostHog, Amplitude, Segment), feature flagging, growth experiments at scale. /li /ul h3What We Offer /h3 ul liCo-founder title with meaningful equity (to negotiate). /li liOwnership of product and technical direction. /li liA clear mission with real-world impact on students’ lives. /li liFlexibility on location (Alicante HQ, hybrid, or remote) and willingness to move if product demands it. /li liA culture of speed, candor, and craftsmanship. /li /ul h3How to Apply /h3 pSend a short note with links (GitHub, portfolio, shipped apps) to /p h3Subject: Co-Founder CTO — (Your Name) /h3 pTell us about one product you shipped that changed behavior, what you measured, and what you’d do differently next time. /p h3Important questions to answer /h3 p1) Why EdTech and not any other sector? /p p2) If we asked your friends to describe you under pressure, what would they say? /p p3) What EdTech product would you build based on a pain you’ve lived yourself? /p h3Disclaimer /h3 pOnly applicants submitting their application to the specific email and answering these questions will be reviewed. Thanks for reaching out and happy to meet soon! /p /ul /p #J-18808-Ljbffr
