Senior Design Engineer - MetaMask

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Design Engineer - MetaMask based in Germany. This is an opportunity for a senior frontend-focused engineer to shape intuitive, polished experiences used by millions of people interacting with Web3 products. You’ll work at the intersection of engineering, product, and design, turning complex user flows into fast, accessible, and delightful interfaces. The role combines hands-on development with a strong focus on interaction design, animation, micro-interactions, and visual craftsmanship. You’ll contribute across React and React Native while helping evolve scalable design systems and cross-platform frontend patterns. You’ll also explore AI-assisted and agentic engineering workflows that accelerate design-to-code execution without compromising quality. Working with a globally distributed team, you’ll have significant autonomy while collaborating closely with designers, engineers, and product leaders. Your work will directly influence products and experiences used by a large, global community of Web3 users. Build pixel-perfect, production-ready interfaces using React and React Native, maintaining a high standard of visual and functional quality. Translate Figma designs into accessible, responsive experiences while minimizing friction between design and engineering. Create thoughtful animations, haptics, transitions, and micro-interactions that make digital experiences intuitive and engaging. Contribute to and expand a scalable design system with reusable, accessible components across platforms. Take concepts from early ideas and prototypes through implementation, testing, validation, and production release. Develop AI-assisted and agentic workflows that improve design-to-code processes and increase engineering efficiency while maintaining quality standards. Collaborate closely with designers, product managers, and engineers to solve complex interaction and frontend challenges. Advocate for high-quality product craft and identify opportunities to improve usability, performance, accessibility, and overall user experience. Balance attention to detail and product polish with practical delivery needs, making sound decisions about when to refine and when to ship. Requirements Proven experience as a senior frontend or design-focused engineer building and shipping high-traffic, consumer-facing products with React and React Native. Strong proficiency in modern JavaScript and TypeScript, with experience designing scalable cross-platform frontend architectures. Demonstrated expertise in frontend performance, accessibility, reusable UI patterns, and production-quality engineering. A strong portfolio showcasing polished interfaces, interaction design, animations, motion, and micro-interactions rather than static screens alone. Strong understanding of interaction and motion design, with the judgment to use animation and haptics purposefully rather than unnecessarily. Advanced Figma literacy and the ability to interpret design files and translate detailed designs into production-ready code. Experience contributing to or maintaining design systems and reusable component libraries. Hands-on experience with AI-assisted development, agentic workflows, LLM-based tooling, or similar approaches to accelerating software development. Experience with crypto wallets, blockchain, Web3 products, or related technologies is strongly preferred. Strong autonomy, initiative, and judgment, with the ability to work effectively across a globally distributed and asynchronous team. A collaborative mindset and strong communication skills, with the ability to work productively across engineering, design, and product disciplines. Ability to balance technical excellence and design quality with pragmatic delivery and business priorities.
