Principal Engineer - Scalability

Company:

Depop is the fashion marketplace where the next generation buy, sell and get inspired. We are headquartered in London, UK with locations in Manchester, New York, Los Angeles and Australia. We have more than 20 million registered users in 147 countries. In the UK, 1 in 3 Gen Z/Millennials are registered and in the US we have grown 300% over two years. We are also the only European player to have recently entered the top 25 shopping apps by daily active users.

Our mission is to empower the next generation to transform fashion, and our team of nearly 200 people are dedicated to serving the needs of our global community.

We operate on three pillars:
Community: Our buyers, sellers and employees are inclusive, diverse and accessible. We are committed to empowering diversity within the fashion community.Entrepreneurship: We support our community and help them build their business with Depop. We thrive on supporting innovation by shaping an environment where creators, makers or hustlers can thrive. Sustainability: Depop helps extend the life of garments and reduce waste, we care about the world and want to make a positive change within the fashion industry.
The Role

The Scalability team was historically tasked with taking the worst performing component of our Python/Django monolith, and splitting it out into smaller, more performant, standalone services written in Scala. Having seen some success of this strategy, in combination with focussing on improvements to our legacy codebase, we now have some breathing room and are looking for someone to join a team in taking on the final conclusion of this mission: Breaking apart the remaining components of a large Python/Django monolith into a Scala-based micro/service-oriented architecture.
