Your impact
Onboarding is the first handshake a business has with Mollie, and we’re making it smarter. As a Machine Learning Engineer within our Discovery - Onboarding team, you’ll build the intelligent systems that turn a complex regulatory hurdle into a seamless, automated experience. Your work directly impacts our ability to scale by accelerating how quickly merchants can start processing payments safely.
You’ll bridge the gap between data science and production-grade engineering. We aren’t looking for theorists; we need a builder who can design, deploy, and maintain ML models that solve real-world problems like document verification and risk assessment. By joining this mission, you’ll help us eliminate manual friction and define what the future of automated onboarding looks like in a high-growth fintech environment.
What you'll ship
Build and deploy production-ready ML models that automate merchant verification and onboarding workflows.
Scalable data pipelines and feature stores that power real-time decision-making systems.
Robust MLOps infrastructure to ensure our models are monitored, retrained, and performing at peak efficiency.
Integrated AI solutions that reduce manual intervention, directly shortening the time-to-revenue for new merchants.
Technical documentation and clean, modular code that sets the standard for ML engineering within the team.
What you'll bring
Solid experience putting machine learning models into production environments—you know how to make code run reliably at scale.
Deep proficiency in Python and familiarity with modern ML frameworks like PyTorch, TensorFlow, or Scikit-learn.
Strong engineering fundamentals with experience in SQL, cloud infrastructure (GCP preferred), and CI/CD practices.
A results-driven mindset—you prioritize solving the business problem over building the most complex model.
A collaborative spirit, ready to work closely with Product and Risk teams to turn data into a competitive advantage.
Grow your way
At Mollie, growth is personal. We believe everyone should have the chance to develop their skills, explore new challenges and shape their career on their own terms.
You'll get regular feedback and performance reviews to support your development, with fair and transparent salary reviews along the way. Many Mollies move into new roles or take on new projects to stretch themselves, and we actively hire from within to help you take the next step.
No matter if you're aiming for promotion, exploring a different career path or building new skills, you'll be supported with the tools, trust and opportunities to grow your way.
