Senior Software Engineer (Growth)

Up to £100,000 depending on experience

📍 Salary based on London. Hybrid, with flexible hours.

Fanvue is one of the fastest-growing creator monetisation platforms globally. We're an AI-powered, creator-first platform helping creators connect, engage, and earn directly from their audiences at scale. Following our recent Series A, Fanvue has surpassed $200m+ in annual recurring revenue, with triple-digit year-on-year growth, supporting hundreds of thousands of creators and millions of fans worldwide.

Growth engineering at Fanvue exists to move core product metrics fast. It's a small team that reads out experiments every week, and the surface area is enormous: signup, onboarding, activation, referral loops, retention, and the funnels underneath all of them. There is far more worth testing than there are people to test it. This role exists to close that gap.

🎯 The Role

We're hiring a Full Stack Engineer to work on Fanvue's Growth streams, partnering closely with Product, Design, Data and Marketing to design, ship and iterate on high-impact experiments across acquisition, onboarding, activation and retention.

This is highly execution-focused. You'll be testing ideas in production within your first weeks, not writing specs about them. The team runs on a weekly experiment cadence with real readouts, so the loop between an idea and knowing whether it worked is short, and you own both ends of it.

It suits someone who wants to be judged on whether the metric moved.

🚀 What You'll Do

Design, build and ship growth experiments across signup, onboarding, activation and retention flows

Own features end to end, from idea through implementation, measurement and iteration

Build and refine growth loops such as referrals, sharing mechanics and viral surfaces

Run A/B and multivariate tests, and read the results honestly, including the ones that kill your own idea

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

👀 Who You Are

Strong full stack engineering experience with a clear bias toward shipping

Comfortable across frontend and backend, and willing to go wherever the problem is

Experienced with modern web stacks such as TypeScript, Node.js, React and relational databases

Familiar with experimentation frameworks, analytics tooling and funnel metrics

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

✨ You'll Thrive Here If

You'd rather ship a scrappy test this week than a polished one next quarter

You want to be measured on whether the number moved, not on what you delivered

You're happy to kill your own experiment when the data says so

You go and find the opportunity rather than waiting for it to arrive as a ticket

⚠️ You'll Struggle Here If

You prefer long planning cycles to fast iteration

You need tightly defined requirements before you can start

You optimise for technical purity over measurable impact

You're uncomfortable with a roadmap that changes when the results say it should
