Full-Stack Engineer (Java & React)

Description

Summary: Join a team building a digital identity layer for premium wine using NFC, AI, and a full-stack approach, connecting winemakers with consumers for the first time. Highlights: 1. Exclusive partnership with Amorim, the world's largest cork producer 2. Real hardware × software × AI product with an AI-first roadmap 3. Early team, offering outsized ownership and impact **The Short Version** We're building the digital identity layer for premium wine. Every bottle gets an NFC\-powered digital identity — verifiable, connected, and commercially alive from the cellar to the glass. You'll work across the entire stack: a Spring Boot microservices backend, a React \+ Ionic mobile app, and a React backoffice platform — shipping features that connect winemakers with the people who drink their wine, for the first time ever. AI is at the core of what we're building — from personalised bottle storytelling to an on\-scan AI assistant that turns every tap into a unique experience. **What Corkified Does** A winemaker spends years crafting the perfect vintage. Then the bottle disappears into a distribution chain and is opened by someone the winemaker will never meet. No data. No relationship. No way back. Corkified changes that. We embed NFC tags into corks (in exclusive partnership with Amorim, the world's largest cork producer) and apply tamper\-evident sticker tags to bottles. When someone taps, the bottle comes alive: cryptographic authentication, AI\-personalised storytelling, DTC commerce, consumer insights, and EU Digital Product Passport compliance — all from a single tap. We're not a QR campaign tool. We're not a winery CRM. We're identity infrastructure for physical goods, starting with premium wine. **What You'll Build** Microservices in Java / Spring Boot — account management, catalog, cellar tracking, NFC smart\-cork authentication, engagement, gamification challenges, geotagging, and more. MongoDB\-backed, message\-driven architecture using SNS/SQS for asynchronous communication, deployed on Kubernetes. Consumer Mobile App (React \+ Ionic \+ Capacitor) — cross\-platform iOS/Android app with NFC scanning, AI bottle storytelling, digital cellar, Wine Passport, social tasting experiences, and DTC commerce. TypeScript, MUI, Framer Motion, Firebase Auth/Analytics/Messaging. Producer Backoffice (React \+ MUI \+ Vite) — campaign management, analytics dashboards, bottle logistics, content editing (TipTap), data import/export, and AI\-powered insights for winery clients. TypeScript, Zod, SWR, ApexCharts. AI\-Powered Features — RAG pipelines for wine knowledge retrieval, AI food pairing engine, personalised wine recommendations, intelligent wine profiling, AI sommelier assistant, and an on\-scan AI assistant that adapts every bottle interaction to the person holding it. You'll work with LLMs, build and optimise retrieval\-augmented generation systems, and help design agentic workflows that make every tap smarter. Platform \& Infra — Kubernetes, AWS (S3, CloudFront, Route 53, SNS, SQS), Terraform for infrastructure as code, Firebase ecosystem, Sentry observability, CI/CD via GitHub Actions, API\-first design with SpringDoc/OpenAPI. **What We're Looking For** **Must\-have:** * 3\+ years building production systems with Java / Spring Boot and React / TypeScript * Solid experience with MongoDB or other document databases * Comfortable with RESTful API design and microservice architectures * Experience with message\-driven architectures (SNS/SQS, Kafka, RabbitMQ, or similar) * Experience building or maintaining mobile apps (React Native, Ionic/Capacitor, or native) * Working knowledge of AWS cloud services — S3, CloudFront, Route 53, SNS, SQS, and related * Experience with Infrastructure as Code (Terraform preferred) * Familiarity with CI/CD pipelines and containerised deployments (Docker, Kubernetes) * Active daily use of AI tools for development — you already use LLMs, copilots, and AI\-assisted workflows as part of how you write, review, and ship code * Understanding of AI/LLM fundamentals — you know how large language models work, what RAG is, and how to integrate AI capabilities into real products * Familiarity with AI concepts and protocols: RAG, MCP (Model Context Protocol), AI Agents, and emerging standards like A2A (Agent\-to\-Agent), A2UI, AG\-UI * Strong sense of product ownership — you ship features, not just code * Fluent in English (written and spoken) **Strong bonus:** * Experience building RAG pipelines, working with vector databases, or designing agentic AI workflows * Hands\-on experience with prompt engineering, LLM orchestration (LangChain, LlamaIndex, Semantic Kernel, or similar), or AI agent frameworks * Experience with NFC, IoT, or hardware\-software integration * Knowledge of the Firebase ecosystem (Auth, Firestore, Cloud Messaging, Analytics) * Experience with AI\-powered personalisation — recommendation engines, conversational AI, adaptive content delivery * Familiarity with Spring Cloud and service discovery patterns * Experience with Capacitor / Ionic specifically * Knowledge of DPP (Digital Product Passport) or regulatory compliance tech * Background in wine, luxury goods, or anti\-counterfeiting domains * Experience with DI frameworks like Inversify * Contributions to or experience building multi\-language (i18n) applications **Why Corkified** Exclusive global partnership with Amorim — the company that produces 4 billion corks/year. No competitor can access this. Real hardware × software × AI product — NFC tags embedded in corks, cryptographic authentication, and an AI layer that makes every bottle interaction personal and intelligent. This isn't another SaaS dashboard. AI\-first roadmap — RAG\-powered wine knowledge, AI food pairing, personalised recommendations, intelligent wine profiling, AI sommelier, and an on\-scan AI assistant. If you want to build AI features that touch the physical world, this is the role. Massive market timing — EU Digital Product Passport regulation (2027–2028\) makes digital bottle identity mandatory. We're already building it. Network\-effect business — every bottle tagged, every tap recorded, every consumer connected compounds into the world's richest premium wine consumption dataset — and the AI gets smarter with every interaction. Early team, outsized ownership — you'll shape the architecture, the product, and the culture from the ground floor.
