Who We Are

Zoopla is one of the UK’s most instantly recognisable property brands. In fact, we’re known and loved by over 91% of the nation (and we’re working hard on the other 9%). Our mission is to help the nation make better home decisions - by connecting everyone to their home and giving them personalised insights to help with moving, managing or financing. Over 50 million people visit Zoopla every month to access exclusive data and information on every UK property, search over 500,000 homes for sale and rent, find the best agents and secure the latest mortgage deals.

We’re a growing, dynamic team that embraces innovation and isn’t afraid to push the boundaries. We’re only just starting our journey to redefine the digital property landscape, with much more to explore and achieve. Join us, and transform the way the nation makes home decisions.

What You'll Do

At Zoopla you will design and run the search and retrieval systems behind the consumer portal, serving millions of users. Search relevance, ranking, and the services and data pipelines that feed them sit at the centre of this role. If you care about robust APIs, fast and relevant search, scalable distributed services, observability, and personalisation, this is for you.

You will work primarily in Python and TypeScript across Node.js and GraphQL, with some services in Golang or Perl. You will own search infrastructure end to end on OpenSearch (or Elasticsearch): indexing, query design, relevance tuning, and performance at scale. You will design and maintain the APIs and data pipelines that power it, working across both SQL and NoSQL stores on AWS.

This is a backend role. You will touch the frontend (React and TypeScript) occasionally when a feature needs it, but deep frontend specialism is not expected.

Requirements (all essential)
  • Senior engineer who has built and operated high scale systems serving millions of users, and who can point to the trade offs they made to get there.
  • Production experience with OpenSearch or Elasticsearch: indexing strategy, query and relevance tuning, and keeping clusters healthy under load.
  • Strong distributed systems and systems design skills, with the ability to reason about consistency, latency, failure modes, and scale.
  • Hands on AWS experience running services in production.
  • Fluency in backend development with Python and TypeScript, designing and building APIs and services across SQL and NoSQL stores.
  • A genuine passion for shipping product features with a high level of autonomy and agency, taking an idea from problem to production with minimal hand holding.
  • Excellent communication skills and a track record of working closely with Product and Design to turn ambiguous goals into shipped features.
Also valued
  • Solid engineering craft: maintainable code, code review, pairing when it helps, and meaningful tests.
  • Building for stability, security, observability, and performance, not just the happy path.
  • A commercial mindset that connects your work to business outcomes.
  • You use AI tools as a core part of how you build, from coding assistants to AI driven workflows, and you have a strong sense of where they speed you up and where they need checking.
