FAQ

Can I work fully remote at ML6?

No. We deliberately follow a hybrid setup. We have a strong collaborative culture where we’d like to meet up at least a couple of times a week in one of our offices. Do know that ML6 provides a lot of flexibility in terms of working hours and how you schedule your agenda. Our offices are situated in Berlin, Munich, Amsterdam, Eindhoven and Ghent.

What to expect when joining ML6?

Don’t expect a big corporate organisation with pre-defined jobroles and a defined plan for the coming years. Expect the unexpected. Growth, change and impact. Learn from engaged experts with a like minded passion for technology. Expect to work for the most innovative and biggest companies across countries.

What does a typical AI project look like?

This really depends on the scope of the project. A project can run for a couple of months, to even years. Our ML6ies work on projects together with a team of colleagues. This team can have different skills like data engineering, software, machine learning and project management to deliver top notch service to our clients. They sometimes work on different projects simultaneously or combine project work with an internal project or research topic. We are not an outsourcing firm.

How technically in depth can I go at ML6?

Our company stands for our engineering expertise. You’ll work alongside the most brilliant engineers, with a very in depth technical focus. Some use cases don’t need a very technical in depth solution, some do. At ML6 you can work in different domains (from GenAI to more classic ML), and on different types of client problems. We always make sure that our seniors are linked to more complex problems and to their domain of expertise (ex specific Cloud or Industry).

Is ML6 only a place for juniors to launch their career?

Definitely not. We indeed believe in accelerating young graduates in their career and bringing in new fresh perspectives, but the same applies for seniors. We are always challenging ourselves to expand our capabilities and bring in new knowledge and expertise. People have a personal growth plan at our company, where they can choose to specialise more or to grow further in people and strategy responsibilities. In 2025, 45% of our hires were hired on a senior level. ML6 exposes you to an incredible ecosystem of leading AI talent and will continue to challenge you on a day-to-day basis by bringing you a big variety of projects and business problems.

What about the ethical aspect of AI?

At ML6 we take our responsibility to build secure, reliable and sustainable technology seriously and integrate ethics within our way of working. We have our own Ethical Advisory board to discuss sensitive projects.
