You will join international and collaborative team, with colleagues based across the US, Germany, Poland, and Italy. The team delivers innovative solutions in the field of market research, with a strong focus on brand management.

Our team combines advanced statistical modeling with hands-on software development. We start by designing and validating Proof of Concepts (PoCs) that address real business challenges, and then transform these prototypes into robust, scalable products used globally. This means your work will not end at experimentation—you will be directly involved in delivering and maintaining production-grade solutions that create impact at scale.

As a Machine Learning Engineer, your role bridges data science and software engineering. You will take ownership of turning PoC models into reliable, maintainable, and scalable systems. This includes designing production architectures, optimizing performance, ensuring code quality, and enabling seamless deployment across global environments.

This is a role for someone who enjoys both experimentation and engineering—someone who wants to see their models evolve from initial ideas into fully operational products used worldwide.
