This is a great problem to have as it allows us to train best-in-class machine learning models to prevent previously unpreventable data breaches. We have scaled to the point where there are so many emails flowing through our system that need more human eyes to understand some more advanced patterns and feed them back into our algorithms.You will lead our Threat Intelligence team and work day-to-day with Threat Analysts, Data Scientists and Engineers to build out the flow of identifying any weak points in our algorithms and coming up with ways - in collaboration with our data scientists - to detect these types of emails. You will also work with Sales Engineers, identifying a better flow to surface the value of what Tessian does to our customers, which requires you to deeply understand the product and the way our customers benefit from it.We view this role as a hugely impactful, high-leverage role and strongly believe that if we can have a smooth and robust feedback flow from incoming emails to outgoing ideas that we can deliver more value to our clients through the data breaches we prevent.
