  • You will have advanced knowledge of CSS; the use of Sass pre-processing to create well structured, scalable stylesheets; understanding of organisational approaches such as ITCSS and the use of modular architecture approaches like BEM, OOCSS for managing large pattern libraries.
  • You will have solid understanding and experience of JavaScript and be able to demonstrate usage of the language to enhance website behaviour without reliance on libraries such as jQuery and/or frontend frameworks.
  • Experience of using templating languages to author frontend components (e.g. Handlebars, Mustache, Nunjucks).
