Meet the Team

Our Distinguished Engineer team drives architecture and technical direction for Splunk’s $3.5B platform, ingesting petabytes of data for over 95% of the Fortune 100. As a tight‑knit group of DEs reporting to the VP of Architecture, we operate autonomously while coordinating closely on practical, durable solutions that evolve the platform for future requirements. Each DE owns cross‑organizational domains that shift fluidly as needs arise.

Work alongside exceptionally smart engineers who value rigorous thinking and friendly collaboration—this is where the technical future gets defined!

Impact

Architect and operationalize AI infrastructure as a core component of Cisco Data Fabric, enabling engineering teams to integrate AI capabilities across the world’s largest, most diverse data sets. Design MLOps platforms that solve complex lifecycle challenges—managing embedding model migrations, version compatibility, and continuous model updates—while ensuring operational excellence through monitoring, governance, and serving at petabyte scale. Identify and drive new opportunities for leveraging AI across the stack, establishing consistent architectural patterns for agent prompts, tool integration, and model orchestration.

Build data pipelines and operational frameworks that enable hundreds of engineers to confidently deploy both LLMs and traditional ML models into production. Success is measured by customer adoption and usage of AI‑powered features, alongside operational metrics—model performance, inference latency, and deployment velocity—that directly impact customer value.
