Senior Full Stack Engineer, Growth & Experimentation - Krak

Responsibilities

• 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.
• 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. Our backend is primarily Rust; prior Rust experience is not expected, but enthusiasm for picking it up is.
