3-4 days per week, hybrid work policy in central London office. We're looking for a freelance product engineer to join us between June and October 2026, working primarily on wonderbly.com with a focus on driving growth into Q4. This is a hands-on role involving close collaboration with the VP product and other teams to solve deep customer experience challenges around our Kids and Keepsake landing pages and journeys, in order to unlock growth in these key areas for the business.
You’ll be working within a small, focused team — and at least some of the time, with a fair amount of autonomy. We’re not looking for someone to execute a perfect brief. We’re looking for someone with the judgment to help us figure out the right thing to build, and then build it well.
A few things that are important to us:
- The work you’re doing feeds directly into beautifully made, deeply personal books that people treasure.
- People’s perception of quality has to be high on first contact with our website.
- We’re an AI-first engineering team and want someone who brings that same orientation: using AI tools thoughtfully to move faster and have greater impact by tackling harder problems.
- We also believe the best collaboration happens in person. We’d love you in our Bloomsbury studio on Tuesdays and Thursdays each week. It’s a lovely place to work.
The initial contract is three months, but we expect it to grow as the work and our working relationship develops. We’ll agree a competitive day rate based on your experience.
This role suits someone who is:
- Comfortable working across domains as it involves working closely with our creatives, product, and trading/marketing squads.
- Someone that can rapidly get up to speed with our tech stack and has strong experience in other areas: backend, ecommerce, UX.
- Confident and empathetic in their approach.
- Obsessed with quality because we are the premium personalised book brand in the space.
- Agentic in their approach to everything as we are an AI first engineering team and we are transforming our processes to match.
- We are still learning, hopefully from you, and want to work together to create enduring solutions.
Our tech stack:
- Astro as our headless e-commerce storefront app
- Next for our custom personalisation capture “canvas” app
- Typescript everywhere
- Deployed on Heroku (migrating to Render)
- Prismic CMS and custom ecommerce backend
- Good DX (could you make it better?)
