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.

Founded in 2013, Tessian is backed by renowned investors like Sequoia, Accel and Balderton and has hubs in San Francisco, Boston, and London.

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 senior data scientist with NLP experience ready to work on hard problems, drive best practice and cultivate an environment of experimentation and learning.

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. We're searching for a Lead NLP Data Scientist who is excited about the opportunities and challenges that come with researching, building and deploying real-time production models.

In this role, you’ll get to:

    • 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

We’d love to meet someone who

    • 4+ years Data Science experience
    • Has strong NLP experience (in production)
    • Has worked with, or understands the principles behind working 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
Why we think you'll love it here.... 

It’s important to us that all Tessians are part of the journey we’re on, so we offer equity options with every role and benchmark to provide above market rate salaries - there’s plenty more too….
