D3 Developer

Help us build the future of reading and better support the creative industries!

Jellybooks is looking for an expert d3 developer with design experience available during July 2021 for a fixed term contract lasting about one month.

Two years ago, our multi-national team created the Jellybooks Cloud Reader. Since then we have worked with publishers and bookshops to bring simple, one-click, file-free reading to readers across the world. At the same time, we bring sophisticated analytics to publishers, book sellers, and readers alike using intuitive graphical presentations of data.

Now we are looking for a d3 developer to modernise, improve, and extend our visualisation module. Your tasks will involve moving our d3 code from version 4.9 to to v6, engaging with existing developers to agree on a standard interface to reduce development friction (we have some concrete ideas on this, but you may bring additional expertise to the table) as well as implementing that new interface, and improving the deployment and testing workflow to bring it into line with the other improvements you've made. In addition, we have several new ajax-based visualisations we will want you to develop and implement.

This is a fixed term contract that must end by 31 July. We believe one month will provide ample time to complete the work, although it doesn't include much space for "learning on the job".>/

This is a fixed term contract (FTC) outside the scope of IR35.

Required skills and capabilities

  • Mastery of d3.
  • Experience translating data into pertinent visualisation.
  • Clear understanding of reactive design.
  • Understanding of APIs and designing with sufficient generality to facilitate integration into parts of a pipeline that perhaps perhaps haven’t even been conceived yet.
  • Passion for web performance.
  • Clear understanding of relationships between privacy and data visualisation.
  • Knowledge of source code management, familiarity with git & Github.
  • Familiarity with JavaScript tooling and packaging (npm, webpack, babel), and automated testing (JSDOM, mocha, chai).
  • Good communication and adaptability skills.
  • Passion for books & reading a plus.


We don’t expect the candidate to cover all of the below, but we do expect mastery of at least two of these areas:

  • Several years of experience writing d3 visualisations.
  • Several years of plain vanilla JavaScript coding experience.
  • Prior experience with rewriting and refactoring significant parts of d3 interfaces or implementing an existing specification is highly desirable.
  • Experience with performance improvements.
  • Experience with automated testing.


Please send us a brief note why you think you are a good match for the position to [email protected] along with your CV. Be sure to discuss not only your d3 experience but also your experience with the toolchains and processes that lead to production readiness and your design experience making visualisations that humans understand so easily that they don’t realise something magical has happened. Kindly include links to previous work (Github, links to products you helped develop, etc.), as well. Also please let us know your availability.

Principals only. No recruiters please.
