As a Staff Machine Learning Engineer in our Applied ML & Research team, you'll drive the development of cutting-edge machine learning solutions that power critical features across our online gaming platforms. Your work will directly impact platform security, user experience, and large-scale data-driven decision-making for hundreds of thousands of users daily.

This role blends hands-on technical work with strategic thinking. You’ll lead by example, contribute high-quality code, and help shape the ML roadmap in the organization through cross-functional collaboration.

What you’ll you be doing:

• Identify high-impact ML opportunities and influence stakeholders to prioritize and support these initiatives.


• Design and develop scalable machine learning models — including classifiers, regressors, and rule-based systems — to solve real-world problems.


• Own the full ML lifecycle: from data exploration and feature engineering to model training, evaluation, and deployment.


• Translate complex technical concepts into clear insights for both technical and non-technical stakeholders.


• Set and guide technical direction across ML projects, ensuring technical best practices as well as alignment with business goals.


• Mentor junior engineers and foster a culture of knowledge sharing and continuous improvement.

We're looking for someone with:

• Master’s degree (or equivalent) in Machine Learning, Data Science, Statistics, Mathematics, Computer Science, or a related field.


• 7+ years of industry experience building and deploying ML models at scale.


• Proven ability to lead cross-functional technical initiatives and influence engineering strategy.


• Proficiency in Python (with libraries like PyTorch, XGBoost, Scikit-learn) and SQL.


• Strong experience with machine learning pipelines and orchestration tools such as Airflow, SageMaker Pipelines, or similar.


• Deep understanding of machine learning fundamentals, including experience with Large Language Models (LLMs) and other emerging ML technologies.


• A track record of shipping production-level ML products and maintaining high code quality.


• Excellent problem-solving skills and ability to scope and disambiguate complex ML projects into clear, achievable milestones.

Bonus points for:

• Familiarity with ML tooling such as MLflow, ZenML, or Metaflow.


• Hands-on experience with AWS services (e.g., EC2, EKS, CloudFormation, Cognito).


• Exposure to streaming data platforms like Kafka.


• Contributions to open-source ML projects or publications in ML conferences.
