Backend Engineering at Tessian

 At Tessian, we're building machine-intelligent filters to secure enterprise communications. This involves high volume, low latency data processing for 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 backend engineers to help build out our platform supporting our next stage of growth.

The backend systems power the whole company and our teams have touch points with all of our engineering teams. From deploying data science models in production to integrating with our front end, you'll be involved in projects that span all aspects of the business.

Our teams are made up of people from diverse backgrounds; some have been building Python systems for years and some have learnt the ins and outs of Python on the job.
