Riot Data Scientists combine their broad technical expertise across data processing, automation, machine learning ("ML"), artificial intelligence ("AI"), and experimental design to
inform decisions and develop data-powered products. As a Senior Data Scientist, you’ll dive into projects across all areas of game development and will directly impact Riot’s live games. You’ll
work at a cross team scope, contribute to product vision, inform technical designs, and design datasets & models for our most important data applications.

As a Data Scientist on the Valorant Data Ops team, you will answer the question “How can data help us deliver the best possible player experience,?” You will use
pre-production datasets and simulations to help designers answer their most nuanced game questions. You will build production quality ML models for skill estimation, game
understanding, matchmaking, personalization, and more. You will collaborate with producers, game designers, analysts, and engineers – on game teams directly and in partnership with
shared platform teams. You will report directly to the Data Science Manager within Valorant Studio.

Responsibilities:

• Lead the modeling strategy for deep learning production quality for ML models
• Develop predictive features and signals from gameplay telemetry, unstructured game data, and simulation outputs, ensuring quality, interpretability, and reliability
• Design and implement ML systems using methods including reinforcement learning and imitation learning
• Define evaluation frameworks for game AI that balance generalizable approaches with genre-specific metrics
• Mentor senior and staff-level ML engineers in advanced ML for game AI and architectural decision-making
• Collaborate with game and platform engineers, along with UX teams, to integrate models into production systems in ways that enhance player experience and maintain operational reliability
• Represent the deep learning team and and contribute to shared frameworks

Required Qualifications:

• Extensive experience (4+ years) delivering ML systems in production, including reinforcement learning, imitation learning, or simulation-based training in rich, interactive environments
• Proven ability to design modeling strategies and architectures
• Expertise in developing predictive features and signals from gameplay telemetry, simulation data, or other complex interactive environments
• Strong track record building deep learning systems for dynamic, player-facing environments
• Hands-on experience with relevant ML methods including reinforcement learning and imitation learning
• Mastery of experiment design, model evaluation, and optimization for deep learning
• Track record of incorporating human considerations into AI applications, such as responsible AI practices and human-computer interaction or UX best practices.
• Experience mentoring engineers and collaborating with cross-disciplinary teams.
• Familiarity with integrating deep learning models in live game environments with game and platform engineers

For this role, you'll find success through craft expertise, a collaborative spirit, and decision-making that prioritizes the delight of players. We will be looking at your past studies, experience, and your personal relationship with games. If you embody player empathy and care about players' experiences, this could be your role!

Our Perks:
