Junior Fullstack Engineer – Rapid Prototyping, AI

Responsibilities

• Fullstack Development: Build web-based SaaS pilots and MVPs from scratch (frontend, backend, APIs) using a modern stack (Next.js, Node.js, Supabase).
• AI Integration: Integrate modern AI models (LLM-APIs, HuggingFace, LangChain) into our products and make them usable for SMEs.
• AI-Assisted Coding: Use state-of-the-art tools (e.g., Copilot, Cursor, Cline) to maximize your own workflow.
• Agile Iteration: Work closely with our Testing Architect & Team Lead. Based on feedback and pilot data, rapidly adjust architecture and features.

Qualifications

• Experience in web development: You have already gained practical experience in fullstack development through past jobs, intense side projects, student employment, or hackathons.
• Tech Stack: You have strong knowledge of JavaScript/TypeScript and modern frameworks (React/Next.js, optionally Svelte/Vue).
• Backend Basics: Comfortable with backend (Node.js, REST APIs) and experienced with modern database solutions (Supabase, Firebase, etc.).
• AI Interest: Passionate about current AI developments and eager to work with tools such as LangChain or the OpenAI API.
• Maker Mindset: Write clean code, but your pragmatism wins. You hack, experiment, and learn instead of waiting for 100% perfect architecture.
• Languages: Fluent German and good English.
