• Build screens and components that are maintainable, performant, and resilient, applying established architecture and design patterns

• Write clean, well-tested code and take an active part in code review, applying the team’s engineering standards consistently

• Contribute to technical design discussions within your pod, raising clear proposals and trade-offs for the work you own

• Work closely with Product Managers, Designers, and the Rust backend engineers in your pod to deliver features with measurable customer value

• Help improve code quality, shared components, and tooling across the Krak mobile codebase, keeping current with the React Native ecosystem

What you bring

• 3+ years of experience in software development, with a focus on web or mobile applications

• Solid working knowledge of JavaScript/TypeScript and hands-on experience building with React Native

• Experience integrating and consuming APIs, with attention to security and performance on mobile

• Experience with frontend testing frameworks and modern front-end build pipelines and tooling

• Strong understanding of UI/UX best practices, empathy for the customer, and a passion for building intuitive, performant consumer experiences

• Strong written and verbal communication skills in English

Nice to haves

• Familiarity with native mobile app development (iOS/Android)

• Experience developing micro interactions and animations in React Native

• Experience with Next.js and WebSockets

• Experience within a large technology organization or fast growing startup

• Hands-on experience in consumer payments, crypto or fintech mobile applications

• Working knowledge of Rust (or similar languages such as Go or C++), and familiarity with async architectures, APIs, and microservices

• Experience building large-scale consumer or financial products

• Contributions to open-source or the broader engineering community
