Box is the market leader for Cloud Content Management. Our mission is to power how the world works together. Box is partnering with enterprise organizations to accelerate their digital transformation by creating a single platform for secure content management, collaboration and workflow. We have an amazing opportunity to further establish ourselves as leaders in the space, and we need strong advocates to help us achieve that goal. 

Today, Box powers over 100,000 businesses, including 67% of the Fortune 500 who trust Box to manage their content in the cloud. Our Warsaw office is an incredibly exciting addition to our EMEA expansion. We're already in UK, France, and Germany, and the new Poland location will act as a global engineering and product development hub alongside our headquarters in Redwood City, California.


Box is looking for a Software Engineer to join the Conversion Clients team. The Conversion Clients team's charter is to design, build and maintain services which deal with the conversion of user’s files into various formats that are consumed by a wide range of features. These services are critical to Box's success, enabling rich use cases on top of customer data such as preview, search, real time collaboration, content intelligence, automation, workflows and more. This is a unique opportunity to impact the next generation of content-based features at Box.

There are plenty of interesting challenges to be had such as working on large scale distributed systems, deep diving into advanced file formats and working with a diverse set of technologies and teams.

The Conversion Clients team is part of Box’s backend Storage Platform. Over the past eight years, the Storage Platform has grown from a handful of services just starting to exit the monolith to over thirty micro-services running across multiple US data centers, two US-based GCP compute regions and five global AWS compute regions. In that same period, the Box storage corpus has grown from a few tens of petabytes in a single cloud bucket to over half an exabyte across every major cloud provider in nine global locations. By building the geographically distributed, exa-scale platform powering the next generation of content-driven applications, the team will undoubtably play a key role in Box’s continued content management journey.

As a Software Engineer you will be one of the founding members who will help shape the culture and roadmap of the team.

The work you do will bring a smile to all Box customers :)
