About Tessian

Tessian, formerly CheckRecipient, was founded in 2013 to solve the problem of highly sensitive emails being sent to the wrong people.

Tessian is on a mission to transform the way enterprises secure their communication channels. We build advanced machine intelligence to help organisations protect their communications and filter out threats without them having to define what a threat looks like.


We believe Data Scientists can fall into three valuable roles :

  • You work for a business function analysing & reporting on how to improve a key metric, e.g increasing user conversion
  • You are responsible for writing production models to enhance the main product, e.g recommendation systems for e-commerce
  • 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.

    Tessian is looking for Data Scientists who are excited about the opportunities and challenges that come with researching, building and deploying real-time production models.

    Applicants should have 2+ year's production experience, or have completed a machine learning / statistics / physics PhD and want to become more applied.

    You should have experience owning complex projects from start to finish.


  • Use machine learning to eliminate advanced security threats
  • Brainstorm ideas with your team and quickly mock up prototypes in Jupyter Notebooks
  • We like to focus on new problems so there is little prior research to rely on, so get ready to be thrown into the exciting unknown
  • Learn new technologies and help decide which should make it into our production stack
  • Be responsible for getting your work into production (see here )
  • Work with the back-end engineering team to deploy, monitor and iterate on your models
  • What we offer

  • You’ll work alongside amazing, high-performing colleagues
  • Competitive salary which will depend on your specific experience, with annual benefit and salary reviews
  • Equity options with every role
  • Everyone gets 25 days of paid annual leave (33 days including bank holidays)
  • Company contributions towards your pension
  • You’ll get brand-new high-spec equipment to work on
  • We have a communal company lunch twice a month, and regular team socials and activities
  • Plenty of office snacks including fruit, nuts, bread, and cereals, and amazing coffee
  • Work remotely from abroad for one week
  • Cycle to work scheme, eyecare vouchers and childcare vouchers
  • If you’re coming from abroad, we’ll provide relocation assistance
