Senior Data Scientist

Do you want to apply statistical reasoning, probabilistic modelling, and machine-learning techniques to understand player behaviour, evaluate game changes, and guide product decisions?

We’re looking for a Data Scientist whose strong programming skills and practical analytical experience will enable them to build reliable data systems, automate workflows, and develop models and simulations that help the team make faster and more confident decisions.

THE DIFFERENCE YOU’LL MAKE:

• As a Data Scientist, you will take meaningful ownership in shaping how our games evolve, how we use data throughout the game-making process, and how we introduce modern Data Science practices into daily decision-making. With several years of hands-on experience behind you, you’ll confidently partner with the Product Manager and the broader game team to ensure that decisions are grounded in high-quality data, clear insights, and robust analytical methods. This role blends elements of data engineering and business analytics, with a focus on data science, giving you end-to-end responsibility across the data lifecycle, from how information is captured and transformed to how it is interpreted, automated, and ultimately used to influence player experience and game strategy.

WHAT YOU’LL DO:

Data Science [~50%]

• Performing Causal inference (Econometrics, doubleML, etc.), with a main focus on AB testing
• Modelling user behaviour from real data and using it to power simulations you develop, representing parts of the game. In the process, you will be relying on game theory, applied probability and statistics, and programming
• Applied Classical Machine Learning (from solving complex problems to building production-ready standalone tools and systems)

Data Engineering [~15%]

• Telemetry design, to ensure that new changes in the game are properly and consistently captured by the data
• Writing data transformations and maintaining game data quality

Business Analytics [~35%]

• Making Reports and Dashboards, with a strong emphasis on automation and reliability
• Performing Business Monitoring and alerting, with a focus on automation, scalability, and maintainability of the solution
• Performing Data analysis (from explorational to explanatory)

WHO YOU’LL WORK WITH:

• You’ll partner closely with the Product Manager, Game Designers, Developers and the rest of the game team to ensure that decisions are grounded in high-quality data, clear insights, and robust analytical methods.

WE ARE A MATCH, IF YOU:

• Have 3+ years of experience in Data Science or a related field
• Have a Bachelor's degree in Computer Science or other quantitative fields
• Advanced knowledge of any data visualisation tool (such as Tableau, Power BI, Looker, Qlik, …), as well as visualisation best practices
• Have experience with any OOP, as well as Python or R, and SQL.
• Have strong knowledge of Statistics and Machine Learning concepts
• Love playing games, or following the Gaming industry

BONUS POINTS:

• Generative or Agentic AI projects
• Any experience with cloud computing (such as GCP, AWS, Azure, …) for ML and data infrastructure, big data tools (such as Databricks, Snowflake, Spark, Hadoop, …), or proficiency in MLOps (model deployment, versioning, CI/CD)

WHY YOU’LL LOVE WORKING HERE:

• The team behind the game: transparency and trust from day one, paired with a strong sense of teamwork- that's the essence of who we are. It's not just what you do - it’s how you do it and who you do it with. With 280+ teammates from around the world, we’re on a mission to bring the joy of winning to millions.
• We make your life at Nordeus hassle-free: enjoy Nordeus provided breakfast, lunch, snacks, and beverages, a fully-equipped gym, organized sports activities (yoga, Brazilian jiu-jitsu, basketball, football), an ergonomic workstation, top-notch tech equipment (including laptop, mobile phone and bill coverage, and other tech), a kids’ playroom, a music corner, board and video games + latest consoles.
• Perks? We’ve got plenty: premium private medical insurance for you and your family, flexible working hours, take-what-you-need vacation policy, offsites abroad for the whole company, fully-paid maternity and paternity leave, employee stock purchase plan, access to L&D platforms and opportunities and many more.
• Make your mark on games played by millions: with over 300M registered users, Top Eleven is the world’s most successful football management game. Golf Rival, with more than 60M registered users, is the #2 mobile golf game, aiming to claim the top spot. With one more game in the works, we are continuing our efforts to create powerful mobile sports gaming experiences built to last.
• Meaningful career experience: work with experienced game makers and mentors who will support you from day one, helping you map a career path that's true to you.
• Impact beyond the screen: It is not just about us. We are part of something bigger than a job. We create a better future for generations to come through the efforts of the Nordeus Foundation.
