What you'll do

  • Design, develop, and maintain high-quality consumer-facing features across web (React) and mobile (React Native), owning the full experience from concept to production monitoring
  • Own the full lifecycle of product work, from discovery and technical design through release, monitoring, experimentation, and iteration
  • Drive A/B testing and experimentation strategies: forming hypotheses, designing experiments, analysing results, and iterating based on data
  • Partner with Product, Design, Data, and Mobile engineers to create coherent experiences across Kraken's consumer surfaces
  • Make opinionated technical decisions on framework and architecture choices
  • Set the standard for high-quality code — functional correctness, accessibility, performance, and testability
  • Mentor engineers across seniority levels and contribute to a culture of craft and continuous improvement
  • Lead and collaborate on complex cross-platform initiatives, driving alignment across web and mobile surfaces
  • Stay ahead of the curve on React ecosystem tooling, React Server Components, concurrent features, and streaming
  • Work AI-natively, using AI tools across the full SDLC

What we're looking for

  • 6+ years of professional software development experience with a strong focus on consumer-facing web and/or mobile products
  • Deep expertise in TypeScript and the React ecosystem, with opinions about state management, data fetching patterns, and component architecture
  • Production experience with React Native and cross-platform mobile development, including App Store and Google Play release pipelines
  • Experience with Next.js — App Router, React Server Components, and client/server boundary decisions
  • Hands-on experience with A/B testing, feature flags, and experimentation frameworks (LaunchDarkly, Optimizely, or similar)
  • Experience with WebSockets or Server-Sent Events for real-time UI updates
  • Strong testing culture: Jest, React Testing Library, Playwright or Cypress
  • Familiarity with modern build tooling (Vite, Webpack, CI/CD pipelines) and performance profiling
  • Experience in fintech, crypto, payments, or other high-trust consumer products
  • Strong written and verbal English
  • An active AI-assisted development workflow (Cursor, Claude Code, Copilot, or equivalent) with engineering rigour to review and own what gets produced
