Python Engineer (Machine Learning Focus)

We are a team of experts dedicated to driving innovation through advanced analytics and AI-powered solutions. Our mission is to help organizations become truly data-driven by building cutting-edge technology teams from scratch and expanding existing units.

Currently, we are looking for a Python Engineer (Machine Learning Focus) to support our partner in developing a Global Analytics unit – a centralized team dedicated to strengthening data-driven decision-making and creating smart data products for day-to-day operations.

This role is ideal for someone who thrives in engineering environments, enjoys building ML infrastructure and pipelines, and wants to grow in the field of MLOps. Note: this is not a model development role – Data Scientists handle modeling; you’ll focus on engineering and productionization.

About the Team

The Global Analytics team is an innovative, diverse collective of Data Scientists, Data Engineers, ML Engineers, MLOps Engineers, Business Intelligence Specialists, Software Developers, UX Designers, and more, with a presence across three continents and five countries. The team fosters collaboration, drives innovation, and ensures reliability, transforming the entire organization into a leader in data-driven decision-making.

Your Responsibilities

• Develop production-level ML libraries and reusable Python components for existing and future data products.

• Improve and maintain ML infrastructure for model training, deployment, and monitoring.

• Design and implement scalable and efficient model training workflows for large-scale applications.

• Build and maintain robust, reproducible, and traceable ML pipelines.

• Optimize data ingestion and feature engineering processes.

• Write high-quality Python code in line with engineering best practices.

• Conduct code reviews and provide insightful feedback to peers.

What We Expect

• At least 2 years of professional experience working as a Python Engineer or ML Engineer in an industry setting.

• Strong Python programming skills (must-have).

• Experience writing production-grade code for ML or data-intensive systems.

• Hands-on experience with ML infrastructure (pipelines, deployment, monitoring).

• Proficiency with Azure ecosystem (Databricks, Azure ML, ADF, Azure Functions, etc.).

• Experience with PySpark for large-scale data processing.

• Solid knowledge of SQL and experience extracting data from databases.

• Understanding of data science workflows, without the need to build models yourself.

• Good software engineering practices: clean code, CI/CD, testing, version control.

• Experience working in agile teams.

• Strong communication skills and ability to collaborate in a global setup.

• Fluent English – you’ll communicate with international colleagues daily.

What We Offer

• High-impact projects in AI, Business Intelligence, and IoT.

• Opportunity to grow in MLOps and expand your technical breadth.

• A global, diverse team with a flexible remote work policy.

• A modern office in Warsaw with great transport links.

• No corporate bureaucracy – a casual, collaborative atmosphere.

• Benefits such as Multisport and private medical care.

• Access to online courses, knowledge-sharing sessions, and certifications.

If you are a Python Engineer who wants to work on real-world AI products and build reliable, scalable ML infrastructure – we’d love to hear from you. Apply now and become part of our dynamic team.
