"Every year, senior developers and architects attend QCon events to get answers to the technical questions their organizations are wrestling with: Is our architecture ready for the AI features the product wants? How do I debug a distributed system that fails in ways I can't reproduce? Should we rewrite this application in Rust or optimize what we have? What does a resilient engineering organization look like when half my workflow may change in 18 months?"
"QCon London returns to the Queen Elizabeth II Centre on March 16-19, 2026, bringing together 75+ peer-selected speakers across 15 curated tracks, each exploring the real-world patterns, trade-offs, and architectural decisions from systems that actually run in production. This year's program focuses on the problems senior engineers and architects are dealing with right now. On AI adoption and its organizational impact AI Engineering Architecture in the Age of AI Organizations in Flux: Navigating and Managing AI's Impact on Engineering Teams"
QCon London will take place March 16–19, 2026 at the Queen Elizabeth II Centre and gathers senior developers and architects seeking practical solutions to pressing engineering challenges. The program features 75+ peer-selected speakers across 15 curated tracks that examine real-world patterns, trade-offs, and architectural decisions from production systems. Track themes include AI adoption and organizational impact, scalable and observable systems, resilience, performance, distributed debugging, modern languages and WASM, data architectures, APIs and observability, security, frontend and mobile, and finance technology. Each track is curated by active senior practitioners who prioritize what scales, what breaks, and what matters in practice.
