Data Engineering Brussels Posted Apr 21, 2026

Join Artefact Belgium: Build the Interface of the AI Revolution

Are you a seasoned Full Stack Developer who looks beyond standard web applications? Artefact Belgium is looking for a Senior Full Stack Developer to bridge the gap between cutting-edge Machine Learning and impactful user experiences. If you have at least 3 years of experience in web development and a strong drive to master Generative AI integrations, we invite you to lead the delivery of our next-generation AI solutions in Brussels.

Who You Are

Experienced Builder: You have at least 3+ years of experience in Full Stack development, capable of architecting robust web applications from database to frontend.
Technical Leader: You have a proven ability to manage project workstreams, mentor junior developers, and ensure code quality across the team.
AI Integrator: You aren't just building CRUD apps; you understand (or are eager to master) how to integrate LLMs, manage prompt contexts, and orchestrate AI agents.
Consulting Mindset: You are comfortable interacting with clients, understanding their business needs, and translating complex technical concepts into user-friendly solutions.

Who We Are

Artefact is a leading Data & AI consulting firm at the forefront of AI innovation. While our Machine Learning engineers build the complex models, our Engineering team turns them into usable, scalable, and beautiful products for top-tier clients across healthcare, manufacturing, and media. Our team in Belgium works on the most advanced applications of GenAI, fostering an inclusive culture that encourages creativity, collaboration, and professional growth.

What You Will Do

Build GenAI Web Applications: Lead the end-to-end development of client-facing web applications that serve as the interface for our custom Generative AI solutions.
Collaborate with ML Experts: Work closely with our Machine Learning Engineers to integrate their models into production-ready apps.
Orchestrate AI Logic: Take ownership of the "application intelligence layer." This includes modifying and optimizing prompts, maintaining semantic databases (Vector DBs), and configuring Agentic orchestrations to ensure the AI behaves correctly within the app.
Lead and Mentor: Act as the technical lead on projects, guiding junior developers through code reviews, architectural decisions, and best practices in software engineering.
Client Delivery: Collaborate with client teams to define requirements and deploy solutions that solve real business problems.
DevOps & Deployment: Oversee the deployment of these applications using modern cloud infrastructure and CI/CD pipelines.

What You Bring

Experience: At least 3 years of professional experience in Full Stack development.
Core Stack: Strong proficiency in Python (essential for our AI stack) and modern TypeScript frameworks (mainly Next.js).
GenAI Proficiency: Experience with—or a strong understanding of—integrating LLMs via APIs (OpenAI, Anthropic), working with orchestration frameworks (LangGraph, Agno), and managing Vector Databases (Pinecone, Vertex AI Vector DB, etc.).
Communication: Excellent analytical and problem-solving skills. Proficiency in English is required; Dutch or French is a strong plus.

What We Offer

Competitive Compensation: Aligned with your expertise and experience.
Cutting-Edge Tech: The opportunity to move beyond standard web dev and work hands-on with the latest Generative AI tech stack (Agents, RAG, etc.).
Leadership Role: A position where you can shape the engineering standards of a fast-growing team.
Growth & Learning: Dedicated resources for training, conferences, and certifications in both software engineering and AI.
Global Network: Access to global expertise through Artefact’s international network and opportunities to collaborate on projects worldwide.

This position is based in Brussels, with opportunities to collaborate on projects worldwide.

At Artefact Belgium, we value expertise, leadership, and a drive to innovate. If you're ready to lead and make a tangible impact in the world of generative AI, we'd love to hear from you.
