Do you want to join us on an ambitious mission to secure the digital world?

Keepit is looking for API Integration Developers to join our Backend Team in Krakow, Poland.  

We are growing fast as a company and do our best to bring our SaaS cloud-based backup services to the global audience – and we need tools for that.


Our platform is designed to provide customers with an immutable historical archive of their primary data in systems such as Microsoft 365, Google Workspace, Salesforce, Azure AD, Dynamics 365, and Zendesk. It aims to protect them against everything, from ransomware to simple accidents.  

Most of our back-end components are written in clean, modern C++ 20 using mainly purpose-built components and STL. Several components that deal with business processes and data mining are built using Common Lisp. Everything runs on Linux.  

Backing up billions of objects over foreign APIs using imperfect networks on systems with finite memory and making it all happen in as little time as possible is no small feat.  

If you think solving complex problems is fun, we have strong indications that we will not run out of complicated issues soon. Join us for fun!
