Senior Software Engineer - Frontend - Consumer

📋 Description

• • Build 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 are non-negotiables.
• • 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, streaming, and bring those insights back to the team.
• • Work AI-natively, using AI tools across the full SDLC and expect engineers to have a structured, opinionated workflow, not just autocomplete.
• • 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 — specifically familiarity with App Router, React Server Components, and the client/server boundary decisions that come with them.
• • 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 with Jest, React Testing Library, Playwright or Cypress, and the judgement to know when to use each.
• • Familiarity with modern build tooling (Vite, Webpack, CI/CD pipelines) and performance profiling.
• • Experience in fintech, crypto, payments, or other high-trust consumer products where correctness and user confidence matter.
• • Strong written and verbal English, with the ability to write a clear RFC, give direct feedback in a PR review, and explain a technical trade-off to a non-technical stakeholder.
• • An active AI-assisted development workflow, with the engineering rigour to review and own what gets produced.
