Senior🎓
Top SchoolBrett Henderson is a seasoned technology leader and Chief Information Security Officer based in Queensland, Australia, with a long track record of engineering and management roles dating back to the 1990s. He blends hands-on engineering experience in Java/J2EE and PL/SQL with deep Agile practice, having practiced eXtreme Programming since 2006 and certified as a ScrumMaster coordinating distributed Scrum teams. Brett has led engineering and product teams at companies from TinyMCE (Ephox) to ConsenSys and now advises and runs security for digital consultancies, demonstrating an ability to pivot between product delivery, protocol engineering, DevOps, and security. He is comfortable driving R&D strategy and development best practices while operating across remote, cross-functional environments. A detail that often goes unnoticed is his longevity in technical delivery—progressing from analyst/programmer roles into director and CISO positions, which gives him rare perspective on both code-level tradeoffs and executive risk decisions. His mix of pragmatic engineering, Agile coaching, and security leadership makes him effective at turning complex technical and organizational challenges into measurable outcomes.
