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. In this role you should be a spokesperson both internally and externally in the Threat Intelligence landscape.Some interesting projects we’re working on:Building an advanced threat intelligence infrastructureTraining and Deploying advanced ML models on a combination of structured and unstructured (NLP) data.Improving the deployment flow of algorithm changes to decrease time from idea to productionAutomating reporting to surface product value to our customersDesigning the next generation data-lake setting ourselves up to handle massive future scaleResponsibilities:Look at advanced email attacks and understand the underlying tactics used to try to bypass our systemsLabel these emails to their correct categories to help the Algorithm teams to improve their ML ModelsTake insights from these emails and leveraging our threat intelligence infrastructure to block similar threats in the futureSurfacing these ideas back to the Data Scientists so they can deploy more robust ways of blocking these tacticsPresenting to the wider company about threats we’re seeing to keep them informedTaking calls with customers using our product to understand and surface the value of TessianImproving the tooling for reporting this value back to customersWriting blog posts about new and emerging threatsQualifications:Have basic+ Python knowledge and the ability to look at datasets in PythonHave a real hunger for learning and pushing Threat Intelligence around Email Security to the next levelIdeally have experience in the email security fieldIdeally have some experience with Machine Learning systemsHas an ability to break down ambiguous problems into concrete, manageable components and think through optimal solutionsEnjoys “getting their hands dirty” by digging into complex operationsTakes a high degree of ownership over their workIs a clear communicator with professional presenceHas strong listening skills; open to input from other team members and departmentsHas great attention to detailOur mission to empower and protect people is a reflection of two of our values: Human First and We Do the Right Thing.
