The listing
Payward - the parent company behind Kraken, NinjaTrader, Breakout, xStocks, Payward Services and CF Benchmarks - has spent the last 15 years building one of the most modern and globally accessible financial infrastructure platforms in the industry, built to advance an open, global financial system.
Before you apply, we encourage you to explore our culture page to understand what drives us and how we work.
The team
Founded in 2011, Kraken is one of the world’s longest-standing crypto platforms, trusted by over 10 million individuals and institutions globally. We offer spot trading, margin, futures, staking, and OTC services for both individual investors and institutional clients.
The Consumer Mobile team builds the Kraken app, the interface millions of people use to interact with their money. We work primarily in React Native to make complex financial experiences intuitive, fast, and trustworthy. Our product-minded engineers work closely with Product and Design to understand client problems, challenge assumptions, shape solutions, and measure whether what we ship improves the experience.
We are expanding into Asia and building a new app specifically for Asian users. This requires genuine experience with the region’s distinct user expectations, design language, and technical constraints compared with Western markets.
The opportunity
Build and own high-quality React Native features end to end, from ambiguous client problems and solution design through implementation, launch, measurement, and iteration
Partner closely with Product and Design to shape thoughtful, responsive, and trustworthy financial experiences, including product discovery, trading, and simplified client journeys
Work with APIs and dynamic or real-time data, making strong decisions on state management, rendering, performance, architecture, and reliability
Raise the product-engineering bar through technical discussions, code reviews, collaboration, strong product ownership, and a willingness to move between product and technical challenges
Help build Kraken’s new app for Asian markets. Act as the team’s subject-matter guide on regional UX and design expectations, practical approaches to firewall and connectivity restrictions, and appropriate vendors and tooling such as telemetry solutions
What you bring
Strong React Native experience, including shipping meaningful production applications and making sound architectural and implementation decisions in a modern mobile codebase
A product-building mindset and strong product judgment. You start with the client problem, challenge or simplify requirements when needed, and turn loosely defined problems into measurable product outcomes
End-to-end feature ownership, with the ability to use metrics, experimentation, client behavior, and feedback to assess and improve what you ship
Experience building responsive, data-rich applications using APIs and dynamic or real-time data, alongside close collaboration with Product and Design in written and verbal English
Versatility and thoughtful AI use. You are comfortable wearing multiple hats and use tools such as Cursor, Copilot, or Claude to work faster while retaining responsibility for engineering judgment and quality
Proven experience building and shipping consumer mobile apps for Asian markets. You understand the region’s UX and design conventions, its technical limitations, and how to navigate launch challenges including firewall and connectivity restrictions. You can clearly explain how you have solved these problems before
Nice to haves
Experience in fintech, trading, crypto, payments, or another financial technology environment, with an understanding of trading, investing, or financial products
Experience with real-time or streaming data, and improving mobile application performance, responsiveness, and reliability across a range of devices
Experience across both mobile and web, or 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, including sound judgment about when to work below the React Native layer
Chinese language proficiency, such as Mandarin, or another Asian language
