Company Description
Depop is a peer-to-peer circular fashion marketplace where anyone can buy, sell and discover secondhand fashion. Our mission is simple: to make fashion circular by making secondhand as exciting and rewarding as buying new.
Founded in 2011, Depop’s diverse community has helped move resale into the mainstream, where buying secondhand is no longer an alternative, but how people of different ages now engage with fashion. Today, more than 56 million registered users come to Depop to find great value, express their own personal style and give clothes a longer life. We believe that everything you want already exists, and our role is to help people discover it.
Powered by a team of over 500 people, our company is headquartered in London, with offices in New York. In 2021, Depop became a wholly-owned subsidiary of Etsy - the global marketplace for unique and creative goods - and continues to operate as a standalone company.

We aim to create an inclusive environment where everyone is welcome, no matter who they are or where they’re from. Just as our platform connects people globally, we believe our workplace should reflect the diversity of the communities we serve. We thrive on the power of different perspectives and experiences, knowing they drive innovation and bring us closer to our users.
We’re proud to be an equal opportunity employer, providing employment opportunities without regard to age, ethnicity, religion or belief, gender identity, sex, sexual orientation, disability, pregnancy or maternity, marriage and civil partnership, or any other protected status.

Depop is looking for an experienced Senior Backend Software Engineer to join the Better Matching Experiences (BMX) team permanently.
BMX owns Depop's product discovery and personalisation experience — the highest traffic surfaces in the platform (by orders of magnitude!) and the largest user facing surface area across Depop's engineering organisation.
The team builds and evolves the search, recommendations, and personalisation platform that powers how millions of users discover inventory across the marketplace. This is a cross-functional squad of Backend and iOS Engineers working closely with Product, Data Science, ML Scientists and Design partners, operating in a fast moving, experiment driven environment where user behaviour insights directly shape what we build and how we iterate.
As a Senior Backend Engineer in BMX, you will have a unique opportunity to shape, evolve and scale our discovery and personalisation systems. You will influence how we migrate to modern architectures and help establish strong engineering foundations as we accelerate new user success and continuous discovery.
Independently design and deliver backend solutions to medium-to-large problem spaces, from discovery through production and iteration
Build and evolve core discovery services, pipelines and APIs that power personalisation at scale
Help improve search relevance and recommendation quality by working at the intersection of backend engineering and ML-powered personalisation
Take end-to-end ownership of your work, including design, implementation, testing, observability, and operational support
Contribute to shaping technical direction within the team, improving system design, reliability, and developer experience
Operate in an experiment-led environment, helping define hypotheses, success metrics, and feedback loops
Collaborate closely with Product, Data Science, Design, and other Engineering teams to ensure solutions are well scoped and well understood
Actively contribute to continuous improvement through retrospectives, post-incident reviews, and technical discussions
Mentor and support other engineers in the team, raising the overall quality of delivery
You will shape discovery and personalisation systems that directly influence how millions of users find what they love on Depop
You will work at the intersection of product engineering and data science
You will have real ownership over meaningful problem areas across search, recommendations, and the personalisation platform
You will see direct, measurable impact from your work through experiment results and user engagement metrics
You will help drive a significant architectural evolution as we modernise our service layer
You will join a team that values experimentation, learning, and pragmatic engineering excellence
What are we looking for
Experienced in backend engineering fundamentals with experience independently delivering production systems
Proficiency in at least one backend language such as Scala, Java or Typescript, with the ability to learn new languages quickly

Experience building or operating event-driven systems, such as producing and consuming events or messages in distributed architectures
Experience building scalable and reliable services and APIs
A strong sense of ownership paired with effective collaboration and communication
Comfort working in ambiguous problem spaces and proactively shaping solutions
Solid testing practices across unit and integration levels
Experience working in a DevOps-oriented environment including CI/CD and production monitoring
