Kraken, one of the world's longest-standing crypto platforms (founded 2011, trusted by 10+ million users), is seeking a Senior React Native Engineer to join the Business Services organisation, specifically the Support Center team. This cross-functional team is responsible for support-related experiences across Kraken's products, building and maintaining how clients access help through in-product support, chat, content, and voice-based functionality across web and mobile applications.
In this role, you will develop and maintain high-quality mobile experiences using React Native and TypeScript across multiple Kraken products. Rather than owning a single standalone product, you'll contribute across multiple teams, working with Product, Design, and Engineering stakeholders to understand requirements, align on solutions, and deliver functionality that meets performance, architecture, and UX standards.
Key responsibilities include: developing and maintaining React Native applications; owning initiatives end-to-end from requirements clarification through implementation, release, and post-launch iteration; building support-related functionality such as in-product messaging, chat, content, banners, modals, and voice-call capabilities; adapting your approach to each product's priorities (performance, design precision, reliability, or maintainability); collaborating across Product, Design, mobile, web, and backend teams; writing clean, well-tested code and participating in technical design discussions and code reviews; contributing to real-time experiences using APIs and WebSockets; and helping improve shared architecture and development practices.
Kraken is part of Payward, a parent company that has spent 15 years building a modern, globally accessible financial infrastructure platform. The company offers spot trading, margin, futures, staking, and OTC services for both individual investors and institutional clients.
REQUIREMENTS:
- 5+ years of software development experience, including hands-on experience building and shipping mobile applications with React Native
- Strong working knowledge of JavaScript and TypeScript, with experience using React and modern frontend development practices
- Demonstrated ability to own projects or mobile releases from initial requirements through production delivery
- Excellent organisation skills with a structured approach to managing priorities, dependencies, and cross-functional stakeholders
- Strong written and verbal communication skills in English, with the ability to clarify ambiguous problems and build alignment
- Collaborative, low-ego mindset with flexibility to contribute effectively within products and codebases owned by other teams
- Experience working with APIs, frontend testing, mobile performance, and modern build and deployment pipelines
- Sound technical judgement and attention to detail, with consistent focus on quality, reliability, and completing work
NICE-TO-HAVES:
- Experience with native iOS or Android development using Swift or Kotlin
- Familiarity with Node.js or experience contributing beyond the frontend into backend systems
- Experience building real-time functionality using WebSockets, live messaging, or asynchronous architectures
- Familiarity with customer-support platforms or customer-experience tooling and APIs
- Experience owning iOS and Android build, deployment, and release processes
- Working knowledge of Rust, Go, or C++
- Experience working across multiple products or teams within a large technology organisation
- Previous experience in crypto, fintech, consumer finance, or another highly regulated product environment
