Read more about Engineering at Tessian:
At Tessian, we're building machine-intelligent filters to secure enterprise communications. This involves integrating with and processing data from systems at some of the world’s largest organisations.
Our mission is to keep the world’s most sensitive data private and secure - to do this we're looking for senior C# engineers to help build out our integration offerings supporting our next stage of growth.
In Clientside Integrations we hope to demonstrate to our clients that enterprise software can be done differently. We aim for a minimal-disruption approach to tackling email-based threats and we need our software - and our developers working on our client-side integrations - to enable this. Most enterprise clients access their emails via Microsoft Outlook, so our Outlook add-in is a key integration, and the developer in this role will be working on the product at the very heart of our company.
