Founding Full Stack engineering role on-site in Amsterdam
€70k - €105k base salary + 10-20% bonus + 100-150k€ equity
What if you could build the AI that transforms how European businesses sell?
Venta AI is the leading AI-powered 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
- Take on whatever the moment demands – in an early-stage startup, the lines between roles blur, and that's the point
You won't just build features. You'll help build a company.
Who thrives here
You've built and shipped real products before. You understand what it takes to move fast. You're energized by ambiguity, not paralyzed by it – and you'd rather ask for forgiveness than wait for permission.
You're someone who learns constantly, experiments boldly, thinks in systems – and earns trust through delivery, not promises.
You bring:
- Significant experience as a full-stack engineer, ideally at a medior/senior level
- Strong backend skills in Python
- Solid knowledge in TypeScript and React
- Experience operating software at scale in production environments
- Fluent English with the ability to communicate complex technical concepts clearly
- Genuine alignment with our purpose (our
why
) and our values (our
how
)
Nice to have:
- Experience designing multi-tenancy SaaS architectures
- Familiarity with modern AI coding tools such as Cursor
- Experience with Azure cloud infrastructure
- German language skills to communicate with our mostly German customer base
What this role is not
This is not a job where you'll work on isolated tickets or follow rigid processes defined by others.
- You won't wait for product specs – you'll help figure it out.
- You won't optimize for code coverage metrics – you'll optimize for customer impact.
- We're growing fast – structures evolve, and you'll actively shape them.
Success is measured by what you ship and the difference it makes – not by hours logged or PRs merged.
We reward clarity, real impact, and deep ownership – not activity for its own sake.
If you're thinking:
This sounds like the role where I don't just write code, but help build something that matters
– we should talk.
About Venta AI
Lucas and Stefan founded their first AI company seven years ago (later acquired) and, learning from that journey, launched Venta AI to build AI employees for sales teams. We believe organizations must harness AI to stay competitive, and our mission is to make AI accessible, compliant, and transparent for European businesses.
We raised a € 2M pre-seed round from Y Combinator, Google’s AI fund and others.
Our Why
We believe AI should handle the repetitive, so people can focus on what truly matters. We're here to help our customers win, drive innovation, and strengthen Europe’s economic power.
Our How
We work with structure, speed, and real passion. We celebrate progress, challenge each other, and boldly try new things — always focused on creating real value, not just ticking boxes.

You’ll receive a coding assignment - a mini version of Venta AI - built with our actual tech stack (Python/FastAPI backend + TypeScript/React frontend). You can complete it in your own time and are welcome to use AI coding tools. All expectations and requirements are detailed in the README.
- Follow-Up Code Review Call (30 min)
A call with one of our team members to walk through your submission and discuss your approach.
- On-Site Interview in Amsterdam
Join us for lunch at our office, followed by a 45-minute whiteboard session focused on system design and rapid prototyping.
We typically make an offer the next day (pending a standard background check). We never contact referees without your permission.
The full process usually takes 7–10 days.
