Lottie's marketplace connects millions of families with the right care at the right time. We've built something real - now we need to grow it faster, smarter, and with more precision than a traditional engineering team can.
We're looking for a Senior Growth Engineer to join a small, focused Marketplace team and own the full experiment loop - from hypothesis to code to result. You'll work closely with a PM and designer to run high-velocity tests, feed signal back to Google to sharpen our ad performance, and build the lightweight tooling that lets us learn faster than our competitors.
This is a role for someone who ships first, learns fast, and doesn't look back. If you need things to be perfect before they go live, this probably isn't the right fit.
💻 WHAT DOES THIS ROLE INVOLVE?
- Running end-to-end experiments across Lottie's marketplace, from ideation through implementation to result analysis
- Building and optimising conversion-focused front-end experiences, often with limited design input
- Writing code that sends performance data back to Google to improve ad targeting and campaign efficiency
- Automating parts of our Google Ads configuration and campaign management
- Owning A/B test pipelines and iterating quickly based on real usage data
- Working autonomously within a lean, fast team
💪 WHAT PROBLEMS WILL YOU BE SOLVING?
- Turning traffic into outcomes. Our marketplace is trusted by half a million families a month. You'll be closing the gap between the families who land on Lottie and the ones who find the right care. Every experiment you run is a chance to make that faster, clearer, and more effective.
- Making our ad spend smarter. You'll build the pipelines and integrations that help Google understand what a good Lottie outcome looks like, so our campaigns optimise toward the things that actually matter.
- Moving fast in a space that matters. Care decisions are urgent and emotionally charged. Getting families to the right information faster isn't just a conversion metric. It's a meaningful outcome for real people.
👀 WE THINK YOU’LL BE A GREAT FIT IF…
- You have 5+ years of software engineering experience, front-end leaning with genuine full-stack breadth
- You think in experiments. You can articulate what moved because of your work, not just what you built
- You're comfortable with throwaway work. When a test fails, you kill it and move on
- You're autonomous and low-dependency. You thrive with a hypothesis and a deadline, not a detailed spec
- You're data-driven. You define success before you build, and you look at the numbers before you declare a win
- AI tools like Claude Code are already a big part of how you work, and you’re hungry to get better at them
Sound like you but not quite 100%? Apply anyway - we're looking for potential and passion, not perfect CV match!
💔 THIS ROLE ISN’T FOR YOU IF…
- You prefer depth over breadth and one big build over many small bets
- You need clearly scoped requirements before you can move
- You're looking for a team with lots of process and structure around you
- Our mission to transform later life care
