The role

A Full Stack Engineer will design, build, and ship growth experiments across signup, onboarding, activation, and retention flows. You will partner with Product, Design, Data, and Marketing to iterate on high-impact experiments.

What you will do

• Run A/B and multivariate tests, and read the results honestly
• Partner with Product and Design to prioritise and scope what's worth testing
• Improve the performance and reliability of growth-critical user journeys
• Use analytics and data tooling to guide technical and product decisions
• Continuously find and remove friction in creator and fan funnels

• Comfortable in ambiguity, with a strong bias toward action
• Data-informed and outcome-driven rather than feature-focused
• A clear communicator who works well with product, design and growth partners
• High ownership, high agency, and an appetite for fast iteration

Nice to have

• Experience in the creator economy, consumer subscription, marketplaces or social platforms
• Hands-on with Amplitude, Mixpanel, PostHog or similar
• A track record of growth loops you built that are still running

Benefits
