Top SchoolJof Arnold is a product-focused CTO and co-founder with two decades of engineering experience spanning web, mobile and physical systems, and 11 years in senior software roles. He has built and scaled high-performing teams—creating Tipalti UK's first engineering organisation and driving multiple internal promotions—while championing autonomy, inclusivity and cross-team impact. Technically hands-on, he has driven TypeScript/React/React Native best practices, pioneered a server-rendered native DSL and shipped novel cross-platform AV tooling and a developer-saving design system. His background uniquely blends early adoption of React in production, startup co-founding (including YC-backed FitFu) and deep engineering roots in automotive and aerospace that produced patented manufacturing improvements. Based in the UK, he combines pragmatic product delivery with a penchant for tooling and processes that shrink development cycles and reduce technical debt.
