Summary

Rockstar🎓
Top SchoolQian Bradley is a Senior Staff Software Engineer in the San Francisco Bay Area with 11 years of focused industry experience and a background that spans physics research to large-scale production systems. He has led major initiatives at PayPal, architecting an OpenTelemetry-based observability platform that handles petabytes of logs and trillions of messages daily, and built next-generation L7 routing and service-mesh solutions in Go. Comfortable across JVM and native stacks, he contributed to the open-source squbs project by adding Java APIs and tests to Akka-based streaming modules, demonstrating pragmatic cross-language integration skills. His work combines systems design, cloud productionalization in GCP, and infrastructure-as-code automation to deliver resilient, highly available pipelines. Uncommonly for a senior software engineer, he brings a PhD-level grounding in physics and simulation, which informs a data-driven, statistical approach to observability and streaming problems. At BILL today, he continues to apply that blend of research rigor and production engineering to solve large-scale reliability and monitoring challenges.
