• Set and evolve the frontend architecture and standards for Earn across all platforms (web + mobile)
• Lead high-impact, cross-app initiatives: major refactors, performance & reliability improvements, shared UI/component libraries or SDKs, and codebase modernization
• Define and enforce frontend best practices, testing strategy, performance budgets, and accessibility standards
• Collaborate deeply with backend, DeFi, and product/service teams to ensure coherent API contracts, state management, and data flow across surfaces
• Work closely with Product & Design to translate complex Earn/crypto concepts into intuitive, user-friendly, and performant UI/UX across user types (krak, consumer & pro)
• Mentorship and technical leadership: guide and review frontend engineers, influence roadmap choices, and act as a cross-pod technical leader
• Architect, build, and maintain scalable, maintainable, high-performance frontend applications across React / Next.js / React Native (or similar) stacks
• Build reusable UI components, shared libraries/styles, and abstractions to support multiple apps and platforms
• Optimize web/mobile performance, reliability, load-times — especially critical for financial and crypto features involving real-time data
• Ensure UX consistency and quality (design system adherence, responsive/mobile-first, accessibility, edge-case handling)
• Define and enforce frontend testing, monitoring, and quality standards
• Collaborate across teams — backend, devops, services, design, product — to shape APIs, data flows, error-handling, and user flows, particularly for Earn features and DeFi integrations
• Serve as a senior technical voice in architecture, tech-strategy, and long-term frontend planning
• You’ll own the core frontend foundation for one of Kraken’s most strategic offerings — Earn, used by millions, across Krak, consumer & pro platforms
• Your work shapes how users interact with high-impact financial and DeFi products — from usability and performance to security and reliability
• As a Staff-level engineer, you’ll influence not just code, but architecture, cross-team standards, and long-term platform scalability
• The role sits at the intersection of product ambition, frontend excellence, and crypto innovation — a rare opportunity to build at scale in a mission-driven domain
