Security at Tessian

At Tessian, our mission is to keep the world’s most sensitive data and systems private and secure. This means that it’s critical we go above and beyond in regards to securing our platform.

We are looking for an experienced Security Engineer to come in and help take our security processes to the next level. 

You'll have great coding skills & a breadth of experience, as well as wanting to get your hands dirty and dig in to the workings of our systems. 

Please note that we're also hiring a Head of Information Security who will own internal non-engineering Security processes & our ISMS. That role sits adjacent to this role's responsibilities, but if that role is also of interest, you can read about it here. We're also open to a hybrid role blending the two - if that's of interest, please apply via this Security Lead Engineer job spec, & flag in 'Additional Information', or your covering note, that you'd consider a hybrid role.
