About the role

Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work in a variety of broader domains.

Responsibilities

Implement and Integrate: Lead the technical execution of integrating modern AI practices into existing engines, tools, and pipelines.
Embed and Accelerate: Deploy onto partner teams across Riot to break down complex AI implementation problems, establish technical direction, and deliver scalable, highly performant solutions.
Build Foundations: Identify when industry-standard tools are insufficient and develop new foundations, middleware, or APIs to connect AI research with practical development.
Manage Ambiguity: Actively navigate highly complex, uncharted technical spaces, communicating trade-offs and building consensus among engineering and product leadership.
