About the role

Senior Full Stack Engineer role on Kraken’s growth and experimentation team. Frontend-leaning full-stack position focused on accelerating acquisition, activation, engagement and trading activity across the Krak app using React Native and supporting backend work.

Responsibilities

  • Build and ship consumer-facing features quickly in React Native and TypeScript, favoring 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.

Qualifications

  • 6+ years of software development experience building and shipping large-scale, consumer-facing applications.
  • Strong, hands-on React and React Native experience.
  • Demonstrated experience running growth experiments at consumer-facing businesses with measurable impact on conversion, activation, retention or revenue.
  • Working backend proficiency: design and implement services and APIs yourself; open to Rust.
  • Strong JavaScript/TypeScript fundamentals, with 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.
