Senior Software Engineer (JavaScript/React)

BUILDING THE FUTURE OF OPEN FINANCE 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.
It offers spot trading, margin, futures, staking and OTC services, with products built for both individual investors and institutional clients.
We’re looking for a React Native Engineer to join our Business Services organisation, contributing to Support Center, a cross-functional team responsible for support-related experiences across Kraken’s products. The team builds and maintains the ways clients access help, including in-product support, chat, content and voice-based functionality across web and mobile applications.
Rather than owning one standalone product, Support Center contributes across multiple Kraken teams. You’ll work with Product, Design and Engineering stakeholders to understand their requirements, align on the right solution and deliver high-quality mobile functionality that meets each product’s performance, architecture and UX standards.
Develop and maintain high-quality mobile experiences using React Native and TypeScript across multiple Kraken products

• Own initiatives end to end, from clarifying requirements and aligning stakeholders through implementation, release and post-launch iteration
• Build support-related functionality such as in-product messaging, chat experiences, content, banners, modals and voice-call capabilities
• Work across Product, Design, mobile, web and backend teams to bring the right people together, resolve ambiguity and drive initiatives forward
• Contribute to real-time experiences using APIs and WebSockets, including Kraken-built alternatives to third-party support tooling
• Help improve shared architecture, components and development practices across Support Center’s web and mobile contributions

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, together with experience using React and modern frontend development practices
• Demonstrated ability to own projects or mobile releases from initial requirements through production delivery
• Strong written and verbal communication skills in English, with the ability to clarify ambiguous problems and build alignment
• Experience working with APIs, frontend testing, mobile performance and modern build and deployment pipelines
• js or experience contributing beyond the frontend into backend systems
• Familiarity with customer-support platforms or customer-experience tooling and APIs
• Working knowledge of Rust, Go or C++
• Previous experience in crypto, fintech, consumer finance or another highly regulated product environment
