Senior Product Engineer, Consumer
Location: Nine Elms, London. Full time, 3 days a week on site. You'll need the right to work in the UK and be based in London. We are not able to offer visa sponsorship for this role.
What you’ll do
- Build a world‑class customer experience across the stack. Ship across backend, web, infrastructure, and into mobile when features cross over.
- Bring AI into how we build. Use AI in your daily work. Share patterns that help the team move faster, and learn from what others discover.
- Help shape AI in our product. AI features in our app are still early. Spot the customer moments where AI can create magic, prototype them, and bring them to life.
- Own delivery end‑to‑end. Pick up a problem, design the solution, ship the work wherever the feature lives, and see it through to production.
- Own on‑call. Be on the rotation, and stand behind what you ship in production.
- Keep production fast and trusted. Watch latency, harden release processes, and protect what customers rely on.
- Raise the bar for the team. Contribute to architectural discussions and the patterns that shape our codebase. Lift the people around you.
You're a great fit if you
- Senior full‑stack experience. 7+ years shipping production code end to end, comfortable across backend, web, and infrastructure.
- Strong fundamentals. Confident with TypeScript, GraphQL, and SQL. At home in NestJS (or a similar Node.js framework) and React.
- Cloud and DevOps minded. Comfortable across GCP or a similar cloud, CI/CD, observability, and modern infrastructure tooling.
- Use AI daily. AI assistants are part of how you build. You bring back patterns that help others get more out of them too.
- Think product, not just code. You measure your work by what changed for the customer, not the lines of code shipped.
- Production minded. Solid grasp of API design, observability, scaling, reliability, and security.
- Care about craft. Clean APIs, attention to detail, and how the system feels to work in.
- Comfortable in uncertainty. You move forward when the path isn't clear, instead of waiting for someone to define it.
- Test as you build. Automated tests are how you ship code you trust.
- Passionate about execution. Curiosity, energy, and a habit of moving things forward.
- Excellent communicator. Clear in how you write and speak, and you love sharing what you learn.
Even better if you
- NestJS. Our backend is a NestJS service, and you'd feel at home when features need backend work.
- React Native. Our consumer apps run on React Native and Expo. You'll touch them when features cross stack boundaries.
- GraphQL Federation. We run a federated gateway across multiple subgraphs, and federation experience makes schema and subgraph work easier.
- Distributed systems at scale. Event‑driven patterns, async processing, real‑time data flows.
- Infrastructure as code. Terraform, Kubernetes, or similar.
- Quick commerce or similar domain. Logistics, on-demand delivery, or another real‑time, high‑throughput consumer environment.
You won’t be a great fit if you
- Need a fully defined process and a large, structured team to do your best work.
- Chase technical perfection at the expense of what the customer actually needs.
- Stall when the path forward isn't clear, or wait to be told what to do.
- Want to stay strictly inside your specialty and avoid unfamiliar parts of the stack.

- 25 days of holiday per year, plus all bank holidays
