Job description

Betfair, the world’s biggest betting community and pioneers of the betting exchange, are currently looking for a Front-end Developer; someone who is an expert at JavaScript, CSS and semantic HTML5, and can apply those skills to create rich, modular, user interfaces for our customers to engage with on our Sports betting website.


This Front-end Developer role will not only challenge your JavaScript and CSS expertise, but will allow you to challenge the status quo, estimating and developing smaller and more defined tasks, within Betfair Technology Agile environment which gives you the best opportunity to voice your views, sharpen your skills, test first, and improve the team's delivery velocity.


For the Front-end Developer to be considered successful in this role, they’ll be expected to: 

  • Be an active and productive member of a multi-functional Scrum team, working with other Developers, QA Engineers, designers, Business Analysts and Scrum Master every day
  • Willingness to work in areas other than your specialism
  • Contribute towards solution design from User Stories
  • Code and test in JavaScript, CSS, HTML and Freemarker
  • Debug and fix defects in existing code
  • Strive to improve the download, rendering and processing performance of all code served to the browser
  • Give positive contribution towards Continuous Improvement and Continuous Delivery

Desired Skills and Experience

In order to do this, these are the skills and experiences we’d like to see highlighted on your CV: 

  • In depth experience of coding JavaScript plus HTML and CSS
  • Solid experience of using client-side JavaScript frameworks, ideally YUI3 but will consider alternatives such as jQuery
  • Solid understanding of how the Web works; e.g. HTTP and RESTful principles
  • Solid understanding of browser performance best practices
  • Familiarity with JavaScript unit testing suites, ideally Jasmine
  • Experience with using advanced HTML5 features  

As well as being at the cutting edge of technology, Betfair has a solid and defined career ladder, giving you the opportunity to create personal objectives that align with the company strategy and help you plan and develop your career. If this sounds like something you’re interested in, then please do apply.
