About the role
In this role at Kraken, you will focus on building and shipping consumer-facing features using React Native and TypeScript. The emphasis is on rapid experimentation, allowing you to own the entire process from hypothesis to measurement, and iterating quickly based on results.
You will collaborate with a team that values agility and innovation, contributing to both frontend and backend development. Success in this position means effectively driving user engagement and conversion through data-driven decisions in a fast-paced environment.
Skills that matter here
- React: You will leverage your React skills to develop features that enhance user engagement.
- React Native: Experience in React Native is essential for building the mobile app components.
- TypeScript: TypeScript will be used to ensure robust and maintainable code in your projects.
- Rust: You will contribute to backend services, utilizing Rust in your development.
- JavaScript: JavaScript fundamentals are crucial for handling APIs and real-time systems.
- SQL: You will use SQL for self-serve analytics to inform your experimentation.
Who this role suits
- You have a strong background in software development with experience in consumer-facing applications.
- You thrive in a dynamic environment and can adapt to changing priorities with minimal direction.
- Your experience includes running growth experiments and making data-driven decisions.
- You possess a proactive mindset and are comfortable with end-to-end ownership of product features.
From the employer
- Build and ship consumer-facing features quickly in React Native and TypeScript, favouring small, high-velocity experiments over long-running projects.
- Own experiments end-to-end – hypothesis, design, build, launch, measurement and iteration – using platforms such as Statsig to test globally or within specific markets.
- Improve onboarding, activation and feature discovery to drive conversion, engagement and trading revenue, iterating rapidly on features that are already live.
- Build viral acquisition features and value-add growth features on top of Krak’s existing product offering.
- Contribute to backend services and APIs wherever an experiment requires it, so you can ship across the stack without being blocked.
- Read your own results, including trade-offs between conversion gains and other metrics, and decide whether to scale, iterate or kill – driving technical decisions autonomously amid evolving priorities and limited upfront planning.
- 6+ years of software development experience building and shipping large-scale, consumer-facing applications.
- Strong, hands-on React and React Native experience is essential.
- Demonstrated experience running growth experiments at consumer-facing businesses, with measurable impact on conversion, activation, retention or revenue.
- Working backend proficiency: you can design and implement services and APIs yourself.
- Strong JavaScript/TypeScript fundamentals, with hands-on experience across APIs, WebSockets and real-time systems, mobile performance, testing, and modern development workflows.
- Practical experience designing, running and analysing A/B tests – feature flags, statistical significance, product analytics, funnel and cohort data – with the judgement to act decisively on what the results show.
- End-to-end ownership of product features and a strong product engineering mindset, with the initiative and adaptability to operate with minimal direction amid ambiguity and frequently changing priorities.
- Customer-facing product experience within fintech, digital banking, payments, trading or crypto is a nice to have.
- Hands-on experience with Statsig or a comparable experimentation platform, including regional and global rollouts.
- Rust experience, given our backend stack.
- SQL and self-serve analytics, so you can pull and interrogate your own data.
- AI fluency.
- Familiarity with how AI tools and patterns have fundamentally shifted your development workflow and problem-solving approach.
- Native mobile development (iOS/Android), distributed systems or microservices, or engineering within a hyperscaling consumer technology organisation.
