Ben Griffith is a Software Engineer VP with 15+ years in web development and over a decade specialising in React and its ecosystem, currently leading engineering at Marex. He has deep experience architecting performance-critical, scalable FinTech UIs and component libraries, often pairing Storybook-driven design systems with pragmatic API design to optimise data flow and client performance. A hands-on technical lead, he routinely drives frontend performance (virtualisation, lazy loading, bundle-splitting), schema-driven validation (Zod), and robust testing pipelines (Playwright/Cypress, Jest), while mentoring engineers and shaping team conventions. Ben is also an active open-source contributor, having improved core linting rules in the sasstools sass-lint project and enhanced JSDoc support in Atom’s language package—evidence of his attention to tooling and developer ergonomics. Fluent in TypeScript, React Native, Node.js and AWS, he combines strong UX sensibility with a preference for humble, collaborative teams that pursue continuously better engineering practices.
