Growth Engineer

Role Overview

• Building features in a full-stack fashion (although primarily frontend) using React and TypeScript.
• Driving feature development by leading technical exploration, defining and scoping work collaboratively, and keeping everyone aligned.
• Running A/B tests and experiments, forming hypotheses, implementing features, and analysing results.
• Maintaining and refactoring different services, keeping the codebase clean for the next engineer.

• Instrumenting analytics and event tracking so we can continually learn and improve.

Requirements

• Proven delivery of web products using React, TypeScript and modern front-end tooling, with clean, maintainable code.

• Strong product empathy & UX instincts, turning complex user journeys into simple and engaging flows.
• Clear, collaborative communication that builds trust with engineers, designers, marketers and stakeholders alike.
• Hands-on ownership of A/B experiments — designing hypotheses, instrumenting tests, understanding the data and communicating results.
• Driven by a growth mindset, you actively seek feedback and learning opportunities to level up your craft, and leverage new AI tools to improve your productivity and maximise your impact.
• Hands-on experience in lean and autonomous teams, comfortable with ambiguity, minimal process, and rapid iteration.
