Job summary

XOXO AI Inc. in San Francisco, CA is hiring a Data/ML Engineer to build scalable data foundations and production-grade ML systems. You’ll architect high-throughput pipelines, define data models, and deploy low-latency feature and model serving that scales under real-world load.

You will collaborate with founders and early engineers to turn prototypes into production, turning messy real-time signals into trustworthy datasets powering core product experiences.

Qualifications

• Shipped data/ML systems from prototype to production with reliability, scalability, and latency outcomes.
• Strong command of data modeling and managing schema evolution in event-driven/streaming environments.
• Deep experience with streaming and real-time processing (Flink, Spark) including correctness under late/out-of-order data.
• Built or operated real-time feature pipelines and/or feature stores for low-latency inference.
• Experience with modern data warehousing (Snowflake, BigQuery) and telemetry/event data standards.
• Able to translate product and business questions into durable datasets, metrics, and contracts.

Responsibilities

• Build and run high-throughput batch + streaming pipelines for analytics, training, and product signals.
• Own real-time feature pipelines and online feature serving for low-latency inference.
• Design and govern dimensional data models; handle schema evolution without breaking downstream consumers.
• Implement and optimize model serving infrastructure to hit strict latency and reliability SLOs.
• Define and enforce event schemas, telemetry standards, and data contracts across teams.
• Partner with engineering, product, and research to turn ambiguous product needs into measurable, durable systems.
