My Client is a customer intelligence consultancy which helps brands, from retailers to car manufacturers, identify and acquire new customers, retain existing customers and launch in new markets by fully understanding millions of consumer passions, mindsets and motivations.

Most brands understand their customers through functional loyalty i.e. what and when they have bought in store or online. However, through analysing multiple data sources, my client looks ahead to anticipate and influence future buying-intent. They combine both functional and emotional loyalty data to create actionable insights to transform and grow your business.

They are looking for someone who can contribute to the design, development and operation of digital products that:

  • Are built, delivered and operate in modern browser and server side environments.
  • Leverage RESTful APIs and the HTTP protocol to form solutions that perform well, are resilient and secure.
  • Are distributed and cohesive, but not formed from too many moving parts or competing/contradictory technologies.
  • Follow established User Experience (UX) patterns and practices, including Responsive Design.
  • Are built using sound engineering practices including good design documentation, unit-testing, code coverage, peer reviews and continuous integration.

Skills & Experience

  • Expert level knowledge of HTML, CSS, and JavaScript (ES6) in the context of modern browser environments.
  • Excellent knowledge of RESTful APIs and the HTTP protocol, including performance and design principles.
  • Expert knowledge of a modern web development framework, preferably React and MV* application design.
  • Skilled in working with CSS pre-processors like Sass or Less, with an eye to recent developments in component oriented CSS.
  • Excellent knowledge of RESTful APIs and the HTTP protocol, including performance and design principles.
  • Applied knowledge in responsive/adaptive design principles and graceful degradation.
  • Excellent knowledge of AWS or Azure and the ability to leverage services and building blocks provided by the likes to deliver applications, services and API.
  • Excellent coding practices including good design documentation, unit-testing, code coverage, peer reviews and continuous integration.
  • Up-to-date with the latest frontend ecosystem trends, techniques and standards.
