You will report directly to the engineering manager for Riot Data’s New, Emerging, and R&D Studio Data team.

Responsibilities:

• Develop and operate large-scale machine learning systems, including gathering requirements, designing production-ready architecture, and sustainably supporting high availability services.
• Build, deploy, optimize and maintain machine learning models.
• Develop game features that integrate machine learning into the game server, backend services, and data warehouse.
• Support data scientists, designers, QA, and analysts with tools and automation that make their workflows more efficient and repeatable.
• Work closely with game designers, engineers, and leadership gather datasets, build prototypes, and look for innovative ways to leverage generative models for game development.

Required Qualifications:

• Bachelor’s degree in Computer Science or related field, or equivalent experience.
• 4+ years of experience as a software engineer (2+ years in data and/or machine learning focused roles).
• Familiarity with common tools for machine learning (e.g. Mlflow, Tensorflow, PyTorch), reinforcement learning, (e.g., RLlib, Gym/Gymnasium), and transformer-based models for language.
• Experience building software across multiple languages (e.g., Golang, Python, or C++).
• Experience with building and maintaining complex event driven systems.
• Experience with the development and operation of large-scale, end-to-end machine learning systems, including gathering requirements, designing production-ready architecture, and sustainably supporting high availability services.
• Experience with data processing (e.g., Spark, BigQuery, DataProc), storage (e.g., S3, Google Cloud Storage), transport (e.g., Kafka, PubSub), and orchestration (e.g., Airflow, Luigi).
• Experience deploying cloud infrastructure (e.g., AWS, GCP) using containers and orchestration (e.g., Docker, Kubernetes), managed using infrastructure as code (e.g., Terraform, Ansible).
• Experience with modern MLOPs platforms.
• Excellent Written and Verbal Communication.
• Excellent collaboration skills.

Desired Qualifications:

• Experience or interest in working with Unreal Engine.
• Familiarity with modern ML platforms (e.g. Triton inference server, Seldon Core).

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!
