AI Factory, an Italian spin-off of AI Venture Builder specialized in developing and deploying AI solutions for enterprises, is looking for a Senior FullStack Engineer with at least 5 years of experience, with full mastery of both frontend and backend, and a strong aptitude for analysis and design of complex systems.
What you will do
- Analyze requirements, design architectures, and lead the full lifecycle of software projects, from requirements gathering to production deployment;
- Design and implement distributed and replicated middleware and backend applications, leveraging Redis as a cache and Redis Streams (including consumer groups) for coordination across instances;
- Design and build modern, responsive web interfaces for AI-powered products, with a focus on usability, performance, and accessibility;
- Build and maintain a shared Design System across products, with a component library documented in Storybook, ensuring visual consistency and a high‑quality developer experience;
- Build conversational UIs and LLM interaction interfaces, handling response streaming (SSE, WebSocket), feedback loops, and prompt‑driven UX patterns;
- Integrate RAG pipelines and semantic search into user‑facing experiences — e.g. document Q&A, augmented search, knowledge assistants;
- Implement integrations with AI model APIs (OpenAI, Anthropic, etc.) across both frontend and backend layers;
- Ensure security, GDPR compliance, and privacy protection across the entire application stack;
- Package complete solutions as SaaS or on‑premise products, managing automated deployment and versioning;
- Collaborate with AI/ML and design teams to translate model capabilities into usable product features;
Requirements
Analysis and Design
- Ability to analyze functional and non‑functional requirements and translate them into solid, scalable software architectures;
- Experience in designing distributed systems, with attention to scalability, resilience, and observability;
- Product‑oriented mindset, with the ability to balance technical debt, feature development, and system stability;
- At least 3 products successfully brought to production, with ownership over the full lifecycle.
Backend
- 5 years of experience in backend development with any language (Java, JavaScript, TypeScript, C, or equivalent);
- Of which at least 2 years of experience with TypeScript as the primary backend technology;
- Strong knowledge of Python as a secondary technology (e.g. FastAPI, scripting, AI/ML integration);
- Proficiency with Docker for containerization and a solid understanding of Kubernetes basics for orchestration;
- Experience with Redis (as a cache and as a message broker via Redis Streams and consumer groups), MongoDB, PostgreSQL, and MySQL;
- Solid understanding of communication mechanisms: JWT tokens, REST APIs, and WebSocket;
- Knowledge of application security, GDPR, and privacy by design principles in system design;
- Experience designing and implementing distributed, replicated backend architectures, with proper concurrency management and cross‑instance coordination.
Frontend
- Strong command of TypeScript/JavaScript and major frontend frameworks (React, Angular, Vue, etc.);
- Experience designing and maintaining Design Systems and component libraries, using Storybook for documentation and visual testing;
- Solid knowledge of state management (Zustand, Jotai, or equivalent), frontend performance optimization, and testing approaches (unit, integration, E2E);
- Hands‑on experience integrating LLM APIs (OpenAI, Anthropic, Gemini, etc.) and handling streaming responses (SSE, WebSocket);
- Good knowledge of modern CSS, CSS‑in‑JS (Styled Components, Emotion), or utility‑first approaches (Tailwind CSS).
Preferred qualifications
- Knowledge of prompt engineering techniques and LLM interaction optimization;
- Familiarity with RAG architectures and vector databases;
- Experience with microservices architectures and service mesh;
- Proven experience in designing scalable architectures and managing the full lifecycle of software products.
Contract and compensation
- Preference for freelancers with a VAT number (Partita IVA); permanent employment contracts also considered based on profile and mutual needs;
- Compensation commensurate with experience and commitment, with the possibility of a customized package discussed during the interview.
Why work with us
- You will work on real AI‑powered products — not prototypes — for companies in industrial, fashion, healthcare, and defense sectors, with thousands of active users;
- You will have full ownership of the technical architecture and the opportunity to design systems end‑to‑end, from backend infrastructure to user experience;
- You will work closely with cutting‑edge AI models and a multidisciplinary team including researchers, ML engineers, and product managers.
