Become a Backend Developer at aizy
At aizy, you don’t build a backend that runs somewhere “in the background.”
You build systems that directly impact performance, data, and growth.
Our platform optimizes thousands of marketing decisions every day.
Your backend makes that possible — fast, scalable, and reliable.
You work on the core of the product:
from APIs and data flows to systems that work together with our AI engine.
What you will do
Develop and maintain our backend in Python (FastAPI)
Build a scalable multi-tenant SaaS architecture
Design and optimize API endpoints for frontend and integrations
Implement caching, session management, and performance optimizations
Integrate with AI systems for campaign and budget optimization
Work with large amounts of data and real-time processes
Contribute ideas on architecture, scalability, and reliability
Actively contribute to the product roadmap and new features
What we are looking for
Strong experience with Python backend development (FastAPI or similar)
Experience with scalable systems and SaaS architecture
Understanding of API design, performance, and data flows
Experience with caching, async processing, or event-driven systems
Ownership of technical choices
Interest in AI, data, and product development
Proactive and independent
A team player who enjoys collaborating from our office in Breda
What you get
Salary aligned with experience and impact
Work on the core of an AI product
Technical freedom and influence on architecture
Direct impact on a platform that is used daily
Plenty of room to build, test, and improve
Fast-growing scale-up with an ambitious roadmap
About Aizy
Aizy helps companies grow faster with AI-driven marketing. Our platform connects data, automates campaigns, and makes performance predictable. This is how we combine human strategy with AI precision to deliver better results every day.
