About the role We are looking for a software engineer with solid experience in modern C++ development. The ideal candidate will take ownership of implementing assigned features and components, ensuring robust design, high-quality delivery, and long-term maintainability.

A proactive approach, strong collaboration skills, and a commitment to continuous improvement are key to success in this role. About us Our platform provides customers with an immutable, historical archive of their data in systems such as Microsoft 365, Google Workspace, Salesforce, Entra ID, Dynamics 365, and Zendesk. We protect our customers against everything, ranging from ransomware to simple accidents. The majority of our back-end components are written in clean, modern C++ using mainly purpose-built components. Components responsible for business processes and data mining are built using Common Lisp. Everything runs on Linux. We pride ourselves on backing up billions of objects over foreign APIs using imperfect networks on systems with finite memory and making it all happen in a performant, reliable, and predictable way.
