About this role
Join Kraken as a Senior Frontend Engineer to build high-quality consumer-facing features across web and mobile. Collaborate with cross-functional teams and drive experimentation strategies in a fast-paced environment.
Description
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. Before you apply, we encourage you to explore our [culture page](https://www.kraken.com/culture) 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 across the globe. It offers spot trading, margin, futures, staking, and OTC services, with products built for both individual investors and institutional clients. The Consumer team owns the Kraken app experience used by millions of traders and crypto newcomers worldwide, the product that turns someone's first crypto curiosity into a long-term relationship with Kraken. We build the interfaces people actually use to buy, sell, manage their portfolio, and interact with their assets. Our stack is React on web and React Native on mobile, and we ship fast, measure everything, and iterate based on real user behaviour. We work agile, globally distributed, and we care as much about why we build something as how we build it.Responsibilities
What you will do
- Design, develop, and maintain high-quality consumer-facing features across web (React) and mobile (React Native), owning the full experience from concept to production monitoring.
- Own the full lifecycle of product work, from discovery and technical design through release, monitoring, experimentation, and iteration.
- Drive A/B testing and experimentation strategies forming hypotheses, designing experiments, analysing results, and iterating based on data.
- Partner with Product, Design, Data, and Mobile engineers to create coherent experiences across Kraken’s consumer surfaces.
- Make opinionated technical decisions on framework and architecture choices.
- Set the standard for high-quality code — functional correctness, accessibility, performance, and testability are non-negotiables.
- Mentor engineers across seniority levels and contribute to a culture of craft and continuous improvement.
- Lead and collaborate on complex cross-platform initiatives, driving alignment across web and mobile surfaces.
- Stay ahead of the curve on React ecosystem tooling, React Server Components, concurrent features, streaming, and bring those insights back to the team.
- Work AI-natively, using AI tools across the full SDLC.
Requirements
What you bring
- 6+ years of professional software development experience with a strong focus on consumer-facing web and/or mobile products.
- Deep expertise in TypeScript and the React ecosystem.
- Production experience with React Native and cross-platform mobile development.
- Experience with Next.js — specifically familiarity with App Router, React Server Components, and the client/server boundary decisions.
- Hands-on experience with A/B testing, feature flags, and experimentation frameworks.
- Experience with WebSockets or Server-Sent Events for real-time UI updates.
- Strong testing culture with Jest, React Testing Library, Playwright or Cypress.
- Familiarity with modern build tooling and performance profiling.
- Experience in fintech, crypto, payments, or other high-trust consumer products.
- Strong written and verbal English skills.
