Data and Threat Analyst

Tessian
Tessian protects every business’s mission by securing the human layer 💫
We're building intelligent security that works for human beings as they are, not how security policies would like them to be. Using machine learning technology, Tessian automatically predicts and eliminates advanced threats on email caused by human error - like data exfiltration, accidental data loss, business email compromise and phishing attacks - with minimal disruption to employees' workflow. As a result, employees are empowered to do their best work, without security getting in their way. You can read more about Human Layer Security here.
Tessian has raised a $74m Series C led by renowned security investors, March Capital (Crowdstrike, Knowbe4), with follow-on from Sequoia, Accel, Balderton, Latitude, Okta, Sozo, Citi & Schroder Adveq, to further our mission to secure the human layer.
Founded in 2013, Tessian is backed by world-class venture capital investors, has hubs in London, San Francisco, Boston, and Austin, and London, and is one of the Top-3 2021 Best Places to Work for Women.
As a high-growth scale-up, our email datasets are growing at an exponential rate. 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 sit in 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.
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 scale
Summary of day to day activitiesLook 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 customers
