Senior Full-Stack Developer (React + FastAPI) – AI & Software Start-Up – Antwerp
We are working with a bold new AI consultancy and custom software development start-up based in Antwerp, helping companies turn complex challenges into intelligent digital solutions. From AI integrations to fully tailored platforms, they partner with forward-thinking clients to create real impact.
To support their growth, they're looking for a Senior Full-Stack Developer to build their Full Stack Development team around — someone who writes clean code, loves solving real-world problems, and is ready to play a key role in both strategy and execution.
What You’ll Do
* Lead the development of AI-powered platforms and smart digital tools
* Work hands-on across the React front end and Python (FastAPI) back end
* Collaborate with AI engineers and consultants to turn business challenges into technical solutions
* Set the bar for code quality, architecture, and development workflows
* Speak directly with clients to understand their needs and drive project success
Who You Are
* 5+ years of experience in full-stack development
* Deep knowledge of React and strong experience with Python (FastAPI)
* Solid understanding of REST APIs, databases, and cloud infrastructure (AWS, Azure, or GCP)
* Excited about working on AI-driven products (prior AI experience is a bonus, not a must)
* A proactive communicator who enjoys working directly with clients and cross-functional teams
* Fluent in Dutch and English (both written and spoken)
* Comfortable in a start-up environment where flexibility, autonomy, and initiative are key
What They Offer
* A high-impact, foundational role in a growing start-up
* Real ownership and input into their tech stack, architecture, and culture
* A chance to work on cutting-edge AI projects with diverse, forward-thinking clients
* Hybrid work model – join them at their office in the heart of Antwerp 2/3 days per week
* Competitive Salary Up to €90,000
* A supportive, ambitious team that loves building great software — and having fun doing it
