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. For more information, visit www.depop.com.
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.

Role Description
Depop is looking for a skilled Software Engineer to join us within our Platform Pillar, working on the team that owns and evolves Depop’s core APIs and services.
The Platform Pillar is part of Depop’s enablement function, responsible for building and running the internal foundations that help Depop engineers ship software safely, confidently, and efficiently. Rather than focusing primarily on user-facing features, Platform teams create and maintain the systems, tools, infrastructure, and engineering capabilities that other teams rely on every day.
This team owns and manages Depop’s core application, which sits at the heart of the platform and is responsible for managing critical user and product data. It is a foundational part of Depop’s technology estate, supporting many of the experiences used by buyers, sellers, and internal teams across the business.
This is a unique opportunity to help shape the technical direction of one of Depop’s most important backend systems. You’ll be working on highly impactful platform problems, improving scalability and reliability, reducing technical risk, and helping define how Depop’s core systems evolve for years to come.

- Improve the scalability, reliability, observability, and operational safety of critical backend systems.
- Work on foundational platform capabilities, including core backend systems, service-to-service communication, authentication, infrastructure architecture, messaging, database scalability, deployment tooling, and internal engineering enablement.
- Help evolve Depop’s core application so it remains safe, performant, and fit for future product and engineering needs.
- Communicate clearly with stakeholders across engineering, product, security, data, and infrastructure, translating technical complexity into shared understanding and actionable plans.
- Support applications end to end, including production incident management, debugging, monitoring, and continuous improvement.
- Embrace agile methodologies, user-centred thinking, and a pragmatic approach to solving real business and engineering problems.
- Engage in a culture of continuous improvement by participating in blameless post-mortems, architecture reviews, engineering guild sessions, and technical strategy discussions.
- Collaborate daily with fellow engineers in a cross-functional environment to solve complex problems and write high-quality code.
- Mentor and support the growth of colleagues, identifying opportunities to share knowledge and strengthen team skill sets.
- Own your code, workflows, services, and data through their entire lifecycle.
