Do you love modern web technologies? Are you a team player who likes solving difficult problems together? Do you want to join one of the UK's most exciting tech start-ups and play a key role in developing an ambitious product with a global impact?

Flourish is empowering the world to visualize and tell stories with data. It enables anyone to create beautiful graphics, presentations and interactive stories without coding.

Since our launch in 2018, more than 500,000 registered users have produced more than 5 million graphics, which have racked up more than ten billion views.

Our customers include leading newsrooms (such as BBC and FT), major corporates (such as Goldman Sachs and Moody's), NGOs (Amnesty, Rockefeller) plus universities all over the world.

We're looking for a senior developer to join our team, reporting to the head of software development.

The role

You'll be a senior developer in one of our small technical teams, overseeing the creation of significant new features on the Flourish platform. You will :

  • Develop new features for Flourish, using modern web technologies
  • Maintain standards for web performance, security and accessibility
  • Build automated tests and improve the observability of the codebase
  • Pair-program and review code
  • Help improve the way we work and the tools we use
  • This is a thoroughly hands-on development role : most of your time will be spent working with code. But you will also mentor and manage other developers and work closely with the product team.

    This role is mostly focused on the Flourish platform rather than the visualization templates, which are developed separately.

    About you

    You are an experienced developer who enjoys working collaboratively and loves to learn new things. You care deeply about the quality of your work and are thoughtful about how to improve both what you're doing and how the team works together.

    You're happy to adopt existing conventions of the codebase.

    Importantly, you're excited by Flourish and the opportunity to make it better. You're a friendly colleague and you work well in a close-knit team.
