We are looking for a Senior Machine Learning Engineer to design, own, and scale predictive systems that power VIS.X - programmatic advertising platform.  
You will take end-to-end responsibility for high-impact ML initiatives (e.g., pricing optimization, bid prediction, performance forecasting, delivery optimization) and translate complex business problems into robust, production-grade machine learning systems.  
This is a senior individual contributor role with leadership potential. You will help shape our ML architecture, standards, and long-term AI strategy, with the opportunity to grow into a team lead role as we expand our data science capabilities.

### Requirements:

-   Solid knowledge of statistics, experimentation design, and model evaluation
-   Experience working with large-scale datasets and performance-critical systems
-   Understanding of MLOps principles (model lifecycle, monitoring, CI/CD integration, retraining pipelines)
-   Strong problem ownership mindset - ability to independently structure ambiguous challenges
-   Ability to translate business trade-offs into modeling decisions
-   Experience in AdTech, marketplaces, or auction-based systems is a plus
-   Experience working in high-scale, real-time systems is a plus

### Responsibilities:

-   Take ownership of machine learning problems from concept to production
-   Design, build, and deploy predictive models (e.g. pricing, bidding, optimization, forecasting)
-   Develop scalable feature engineering and data pipelines for large-scale datasets
-   Define experimentation frameworks (A/B testing, offline validation, model comparison)
-   Ensure production-grade MLOps: monitoring, retraining, drift detection, reliability
-   Collaborate closely with DevOps, Product, Engineering teams to align ML with business impact
-   Quantify model impact on revenue, margin, and performance KPIs
-   Contribute to building our long-term ML architecture and best practices

### What we offer:

-   Comfortable environment, challenging tasks and a long-term interesting project;
