Data Engineer, Riot Games

• Bachelor’s degree in a related field, or equivalent practical experience
• 8+ years of experience in data engineering, software or application engineering, or an adjacent enterprise technology role
• Hands-on experience building production data pipelines, including ingestion, semantic or domain modeling, data quality, and lineage
• Hands-on Databricks experience, including Unity Catalog, medallion architecture, and Mosaic AI or model serving
• Hands-on experience shipping production AI solutions, such as retrieval-augmented, conversational, or agentic applications, grounded in data pipelines you built
• Proficiency in Python and strong software engineering fundamentals, including testing, code review, CI/CD, deployment, and production support
• Experience integrating enterprise systems through APIs, events, or middleware, including authentication, retries, reconciliation, and auditability
• Experience with an LLM or cloud AI platform such as Vertex AI, Anthropic, or OpenAI and an automation platform such as Workato, n8n, Camunda, or similar
• Working knowledge of data governance, privacy, and security practices applied to production data pipelines and products
• For this role, you’ll find success through craft expertise, a collaborative spirit, and decision-making that prioritizes your fellow Rioters, who are the customers of your work. Being a dedicated fan of games is not necessary for this position

Desirable

• As a Staff Data and AI Engineer on the Enterprise Data & AI team, you will build the governed data foundations that power enterprise analytics, automation, and applied AI
• Your primary focus will be data architecture and data engineering, where you will be responsible for designing and operating production data pipelines in Databricks, integrating & curating data through a medallion architecture, and defining semantic and domain models in Unity Catalog with subject-matter experts
• You will also build agents and retrieval-augmented applications directly on this governed data using Databricks capabilities such as Unity Catalog functions, Mosaic AI, and model serving
• You will own your systems from architecture through production operations, applying strong engineering, data quality, security, evaluation, and observability practices throughout
• The ideal candidate is a hands-on data and software engineer who can turn ambiguous enterprise needs into reliable data products and focused AI-enabled solutions
• The role will report to the Senior Manager, Enterprise Data and AI
• Data Pipelines and Semantic Layer (Primary):
• Build and operate pipelines that ingest source-system data into Databricks using a medallion architecture across bronze, silver, and gold layers, with lineage, provenance, access controls, and logging
• Partner with subject-matter experts to define and evolve domain, ontology, and semantic models in Unity Catalog, then curate reliable data products into those models
• Own data quality for the pipelines and products you build, implementing tests, monitoring, and alerting so issues surface before they reach downstream consumers
• Integrate enterprise systems through APIs, events, and middleware while applying appropriate authentication, retries, reconciliation, and auditability
• Agents on the Databricks Data Layer (Secondary):
• Build production agents and retrieval-augmented applications grounded in governed Databricks data, using Unity Catalog functions as tools and Mosaic AI or model-serving capabilities
• Add authorization, approvals, and auditability for consequential actions performed through agents or AI-enabled orchestrations
• Create evaluation sets and observability for the agents you ship, including groundedness, latency, cost, and production feedback, and use the results to improve them
• Engineering Fundamentals:
• Apply solid engineering practices, including automated testing, code review, CI/CD, documentation, on-call support, and concise design notes
• Own architecture decisions for your systems and communicate material tradeoffs clearly to technical and business partners
