At Aizy, we build software that helps agencies and webshops manage their online advertising. Our platform collects campaign results, makes recommendations using AI, and can automatically execute changes in ad accounts.
We're looking for a developer who can build features independently, from database to screen. Someone who enjoys thinking along about the product and likes figuring out, together with a growing team, how things can be done better.
What you'll be doing
You’ll work on our own SaaS platform, with integrations to Google Ads, Meta, TikTok, ChatGPT, and more. For example, you’ll build an automation that adjusts ad budgets based on results, including the basic screen where the customer sets conditions and can see what’s been executed.
Build integrations with advertising platforms and process campaign data.
Develop dashboards that let customers track their spend, conversions, and ROI.
Extend our AI assistant, which analyzes data and helps customers prepare and execute changes.
Keep the platform reliable: from fast queries to preventing duplicate executions and properly separating customer data.
You’ll think along on the approach, build the solution, and follow how it works in practice. Because our software can adjust ad budgets, we pay a lot of attention to checks, clear confirmations, and visibility into what’s happening.
Our stack and way of working
The backend runs on Python, FastAPI, and PostgreSQL. On the frontend we work with TypeScript, SvelteKit, Tailwind, and TanStack Query. We use Docker for the development environment.
We work daily with AI agents like Claude Code and Codex. We’re looking for someone for whom AI is a natural part of development, who keeps up with what’s possible and enjoys trying out what works.
You’ll get the space and encouragement to use AI tools extensively — to test ideas faster, build features, and solve tricky problems. We want to discover together how much more productive we can become with them. You keep the overview and judge the quality of the result.
Found an approach that works well? Share it with the team. That’s how we improve our way of developing together.
What you bring
You have experience independently building and maintaining web applications.
You have a solid foundation in Python and have worked with FastAPI or a similar framework.
You can work with TypeScript and a modern frontend framework. You don’t need to be a designer.
You understand databases and can figure out why a query is slow.
You take authorization, customer data, and the impact of changes into account.
You embrace AI as part of your craft and actively look for ways to work better and faster with it.
You enjoy working with colleagues in our office in Breda.
Dutch is our working language in the office. You speak and understand it well enough to easily join in meetings, technical discussions, and casual conversations.
You don’t need to already know our entire stack. We’re mainly interested in hearing what you’ve built, what choices you made, and what you learned from them.
What you get from us
Salary matching your experience and impact.
A friendly team with short lines of communication. We work together in our office in Breda, help each other out, and also make room for a good chat in between.
Room to grow. You can deepen your expertise in areas like architecture, AI, or frontend development and take on more technical responsibility as the company grows.
Influence on the product. You help shape what we build and how we approach it. You can discuss ideas and improvements directly with the team.
Work on our own product. You’ll see how customers use your features and can improve them based on that.
Room to work extensively with AI. We encourage you to try out tools and new ways of working that help you get more done. What works well, we adopt together.
We’re a growing startup. Priorities can shift and there’s still a lot to build. That gives you a lot of room to help shape how the product and team develop.
