Founding Full Stack Engineer
About the role
Amsterdam (The Netherlands) – On-Site
What if you could build the AI that transforms how European businesses sell?
Venta AI is the leading AI sales solution for European companies. Our technology helps companies generate qualified leads, automate outbound processes, and unlock revenue potential that was previously invisible. In 2025 alone, Venta AI has initiated over 500 real deals, proving the economic impact modern AI can deliver in sales.
As a Founding Full Stack Engineer, you won't just write code, you'll shape the core of a product that's already changing how companies grow. You'll own features end-to-end, from database to UI, and see your work directly drive customer success. You'll build alongside the founders, talk to real users, and make decisions that define our technical direction for years to come.
If you've been waiting for the right moment to join an early-stage company where your work genuinely matters – this is it.
What you’ll drive
This is not a role where you'll be handed specs and expected to execute. You'll work on a product that's live, growing, and used daily by sales teams across Europe. You'll shape what we build and how we build it.
You will:
- Own and develop core product features across our entire stack (Python/FastAPI backend, TypeScript/React frontend)
- Collaborate directly with founders and customers to conceptualize, design, and ship new features
- Make architectural decisions that balance speed, scalability, and maintainability
- Debug production issues, optimize performance, and ensure our platform stays reliable as we scale
- Contribute to a codebase that leverages cutting-edge AI and help us push its boundaries further
