Senior Software Engineer - React Native - Consumer

As a Senior React Native Engineer at Kraken, you build the mobile app that millions of people use to interact with their money. You join the Consumer Mobile team, working primarily in React Native to create intuitive, fast and trustworthy financial experiences. You'll think like a product builder, working closely with Product and Design to turn real client problems into thoughtful solutions, comfortable starting with ambiguous problems rather than perfectly defined specifications.

What you'll do

• Own features end-to-end, from understanding the problem and shaping the solution through implementation, launch and iteration, using data and client feedback to drive improvements
• Build high-quality experiences in React Native across a financial product where responsiveness, reliability and trust matter, whether improving product discovery, creating trading experiences, or simplifying journeys
• Partner closely with Product and Design, contributing engineering perspectives early in the product-development process rather than waiting for finished requirements
• Work with APIs and real-time data to create responsive, data-rich mobile experiences, making thoughtful decisions around state management, rendering, performance and architecture
• Operate with the ownership and versatility of a product engineer, comfortable wearing multiple hats and moving between product problems and technical challenges
• Help raise the product-engineering bar across Consumer Mobile through technical discussions, code reviews, collaboration and by demonstrating strong product ownership

What you bring

• Strong React Native experience: you've built and shipped meaningful production applications using React Native and are comfortable making architectural and implementation decisions across a modern mobile codebase
• A product-building mindset with strong product judgment: you start with the client problem rather than the ticket, understand what you're actually trying to solve, know when to challenge requirements or simplify solutions, and work with Product and Design to turn ambiguous requirements into strong engineering solutions
• Evidence of product impact: you can explain not only what you've built, but why you built it and what happened afterwards, and are comfortable using metrics, experimentation and client behaviour to evaluate the impact of your work
• End-to-end ownership: you're comfortable working across the lifecycle of a feature (discovery, technical design, implementation, launch, measurement and iteration)
• Comfort with data-rich applications: you've worked with APIs and dynamic or real-time data and understand the engineering considerations involved in turning that data into responsive client experiences
• Close collaboration with Product and Design: you enjoy working directly with designers and product managers, see building great products as a shared responsibility, and communicate effectively in written and verbal English across a globally distributed team
• Versatility and AI proficiency: you're comfortable moving beyond a narrowly defined engineering remit, use AI tools (Cursor, Copilot, Claude, etc.) thoughtfully to move faster while retaining ownership of engineering decisions and quality, and thrive in environments where you wear multiple hats
• A track record of taking loosely defined product problems and turning them into features or products that delivered measurable client impact

Nice to have

• Experience building products in fintech, trading, crypto, payments or another financial technology environment
• An understanding of how trading, investing or financial products work and an interest in the problems your clients are trying to solve
• Experience with real-time or streaming data and building interfaces where information changes rapidly
• Experience working across both mobile and web, bringing valuable perspective from broader frontend or product-engineering work
• Experience in a startup or small-to-medium-sized technology company where engineers work closely with Product and Design
• Native mobile experience in Swift or Kotlin and an understanding of when dropping below the React Native layer is the right engineering decision
• Experience improving application performance, responsiveness and reliability across a range of mobile devices
