You will make a real difference in our products and players' experiences.

What You'll Do

• Deploy machine learning models that support game features, player experience, and operational efficiency.
• Improve the code quality of others' work by refining SQL and Python scripts for data transformation, feature engineering, modelling pipelines, and AI app, thereby ensuring production readiness.
• Explore and contribute to early-stage projects involving LLMs, RAG systems, and agentic AI to power new types of automation and decision support.
• Develop or refine Streamlit-based tools (or alike) that present ML/AI capabilities to non-technical users via intuitive and interactive interfaces.
• Help build and implement model monitoring systems to ensure long-term performance and business alignment.
• Collaborate with teams across product, data, and engineering to identify where ML and AI can bring value.
• Communicate results, limitations, and recommendations clearly across technical and business collaborators.

What We’re Looking For

• 5+ years of experience applying machine learning to real-world problems, from data to deployment.
• Strong Python skills and hands-on experience with ML Python libraries.
• Solid SQL expertise and experience working with large data warehouses.
• Comfort working with cloud platforms (e.g., GCP, AWS, Azure), Docker, and Airflow.
• Ability to build simple user interfaces (e.g., Streamlit) to expose ML models or AI applications to wider teams.
• Hands-on experience building applications with Generative AI (LLMs), including API integration.
• Interest or early experience in RAG systems - whether through prototypes, side projects, or professional work.
• Interest or familiarity with agentic AI concepts or frameworks (e.g., LangChain agents, CrewAI) is a plus, but not a must.
• Curiosity, initiative, and a desire to learn and grow in a fast-evolving space.
• Degree in a relevant technical field or equivalent experience.
