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.

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.

Data Science at Tessian

Our mission is to secure the human layer. This involves deploying near real-time machine learning models at massive scale to some of the world’s largest organisations to keep their most sensitive data private and secure.

To do this, we're looking for a Lead Data Scientist to lead our Data Science guild at Tessian. This role will be the technical leader for Data Science at Tessian. They’ll work closely with our current Data Scientists and other Engineering teams to drive key projects around research and development, quality measurement and improvements to our algorithms.

Companies can leverage data science in a number of ways, and we think the role of a Data Scientist falls into three distinct categories:

1) You work for a business function analysing & reporting on how to improve a key metric, e.g increasing user conversion
2) You are responsible for writing production models to enhance the main product, e.g recommendation systems for e-commerce
3) You build the product - without machine learning, it wouldn't exist

The Data Science team built the product at Tessian. We couldn't exist without our machine learning models; they are at the heart of what we do, and they are what our clients rely on day-to-day.

In this role, you’ll get to:

Take accountability for the technical leadership of Data Science at Tessian
Work across massive enterprise email datasets
Deploy models to production that impacts directly our customers and products
Improve our ML workflow
Collaborate with engineering and product leaders to develop a product suite that is continually detecting more advanced threats for our customers
Make your mark on leading ambitious projects
Mentor and knowledge share with data scientists at Tessian

5+ years Data Science experience in production and 2+ years technical leadership experience
Is passionate about and experienced in NLP
Has worked with data at scale
Can balance longer term projects alongside impactful quick wins
Cares deeply about the impact their team has
Is a creative at heart, and can encourage novel ways of thinking in their team. This has always been a core part of the data science team’s DNA
Reads Rules of Machine Learning - Martin Zinkevich and it resonates with how they think about machine learning and data science
