With several exciting projects lined up we are now looking to expand the front-end design and development team with another front-end web developer.

As a front-end web developer your primary responsibilities will include supporting both the Design and the Development team to produce front-end code to support multiple client projects. A keen eye for cutting edge web design, interface development, usability and the ergonomics of a system are as important as a mind for innovation and the ability to work effectively in a pair / LAMP development team environment.

In return, we offer a competitive salary, the chance to work on a variety of innovative projects, using advanced process, tools and techniques within a strong, experienced, creative & smart team.

Developing cross-browser and cross-platform compatible solutions
Experience with SASS / BeM Coding Standards
Experience working with version control systems such as GIT
Experience with Javascript frameworks (AngularJS, React)

The Right Candidate:

Will be organised, punctual, detailed, accurate, work quickly to tight deadlines and excel at problem solving
Be able to plan and execute multiple projects
Can accurately translate UX wireframes and design mock-ups into well-organised front-end sites
Will work closely with designers and back-end developers as well as quality assurance teams
More than anything, has a passion for what they do and will always be looking to learn and stay current with developments in all relevant technologies, both software and hardware

Good to have:

Experience with testing frameworks (Jest, Mocha, Chai etc)
Experience with Isomorphic React Applications
Experience working with APIs / GraphQL
Good knowledge of mobile environments, especially iOS & Android
Experience with NodeJS

Human skills are very important and you should enjoy working in a team environment, cope well with pressure, and have a genuine enthusiasm for all things web application development and a “can do” attitude. You will need to manage and prioritise a varied workload and enjoy a customer-focused development role working on diverse projects.
