Data Science at Tessian

At Tessian, we're building machine-intelligent filters to secure enterprise communications. This involves deploying near real-time machine learning models at massive scale to some of the world’s largest organisations.

Our mission is to keep the world’s most sensitive data private and secure - to do this we're looking for data scientists who pride themselves on their ability to learn new skills, are comfortable with the unknown, and are willing to experiment.

We believe data scientists can fall into three valuable roles:

  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 are the product


Tessian couldn't exist without our machine learning models; it’s at the heart of what we do, and it’s what our clients rely on day-to-day. We're looking for data scientists who are excited about the opportunities and challenges that come with researching, building and deploying real-time production models.

We're looking for applicants with a minimum of 2 year's production experience, or you've completed a machine learning/statistics/physics PhD and want to become more applied. You should have experience owning complex projects from start to finish.

As a Tessian Data Scientist you will

    • Use machine learning to eliminate advanced security threats - our models are built to detect anomalies in the intricacies of human-to-human communications
    • Brainstorm ideas with your team and quickly mock up prototypes in Jupyter Notebooks
    • Be thrown into the exciting unknown - we like to focus on new problems so there is little prior research to rely on
    • Be responsible for getting your work into production (see here)
    • Work closely with the backend engineering team to deploy, monitor and iterate on your models
    • Learn new technologies and help decide which should make it into our production stack

Why we think you'll love it here

    • You’ll work alongside amazing, high-performing colleagues
    • We offer a competitive salary which will depend on your specific experience, with annual benefit and salary reviews
    • Equity options are offered with every role
    • Everyone gets 25 days of paid annual leave (33 days including bank holidays)
    • Company contributions are made towards your pension
    • You’ll get brand-new high-spec equipment to work on
    • Flexible start times on the Engineering team
    • We have a communal company lunch twice a month, and regular team socials and activities
    • There are plenty of office snacks including fruit, nuts, bread, and cereals, and amazing coffee
    • We offer a cycle to work scheme, eyecare vouchers and childcare vouchers
    • Weekly yoga sessions in the office
    • If you’re coming from abroad, we’ll provide relocation assistance including flights, accommodation in an AirBnB for 3 weeks, and salary payments to an international bank. Over 25% of the company is international and we’re always as supportive as we can be in helping people make the move
