At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there. A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone. The Optimize team builds the analytics and LiveOps tools that millions of Roblox creators use to understand and grow their experiences: - Creator Hub analytics dashboards and benchmarks; - custom events and funnels; - experiments (A/B testing), Remote Configs and Segmentation; - the observability features behind them. We're looking for a principal engineer to set the technical direction for the data systems behind these products and to be accountable for how they perform at Roblox scale. That stack spans ingestion through Kafka, stream processing in Flink, batch processing in Spark/Hive with orchestration in Airflow, serving through Druid and StarRocks, and the C# services behind Experiments and Configs. You'll define where this architecture goes over the next several years, lead the hardest problems in it hands-on, and raise the technical bar of the engineers around you. Roblox is heading into its highest-traffic season, and our focus is performance and reliability. You'll own the strategy that makes creator data faster, cheaper and more correct, so that creators can trust the numbers they make decisions on. ### Key responsibilities - Set the technical vision and architecture. - Own the multi-year architecture and roadmap for Optimize's streaming, batch and serving systems. - Decide what to build, buy, consolidate or retire, and make the trade-offs between freshness, correctness and cost explicit. - Write the tech strategy docs and lead the design reviews that set direction across the team. - Be accountable for data correctness and reliability at scale. - Define the standards for handling late and out-of-order data, backfills, replays and data-quality validation. - Define the SLOs and the loss/lag alerting (late-drop rate, consumer lag, input-vs-output gaps) that creators' trust depends on. - Lead response to the most serious data incidents, drive blameless postmortems, and make sure the fixes stop the whole class of failure, not just the one instance. - Take part in the team's PagerDuty on-call rotation. - Lead performance, scale and cost. - Own capacity planning and load testing for seasonal peaks across the pipelines. - Lead deep performance work on Kafka partitioning, Flink parallelism, state and checkpointing, and Druid/StarRocks ingestion and query serving. - Drive cost-efficiency strategy (storage retention, table lifecycle, cluster right-sizing) with measurable targets. - Shape the experimentation and LiveOps platform. - Set the architecture for Experiments, Remote Configs and Segmentation: assignment, sticky enrollment, targeting, exposure logging and results pipelines. - Partner with IXP and Data Science on statistical correctness and metric definitions. - Lead across org boundaries. - Represent Optimize in technical decisions with Data Platform, Streaming, Engine and ESP on shared infrastructure, such as the Powerhouse pipelines, QaaS-managed Kafka and the creator compute cluster. - Build alignment and drive multi-team initiatives to completion, influencing without authority. - Multiply the team. - Mentor senior engineers and grow the next technical leaders on the team. - Set engineering practices for design quality, operational excellence and AI-assisted development. - Partner with engineering, product and design leadership on planning and prioritization. --- Data: alder (https://alderhq.app).
