Front-end Web Developer

London, London

£50000 - £60000 per annum.

Competitive salaries

Type: Permanent

Date added: 05/06/17

We’re building technology that enables the big stores to operate as a single digital marketplace, with all of the advantages of a marketplace for smaller retailers (Amazon and Etsy); 1 stop shop, easy comparison, single checkout. 

To do this we need to first amalgamate 3 million products from the top 200 retailers and make sense of them. We need to understand what a product is, it’s true availability (sizes, in stock), how it relates to other products (for comparison) and who to show it to (relevance). 

The Tech

We achieve this using various search, image recognition, macro, AI and API technologies. Over the past twelve months we have built a robust, horizontally-scalable and performant back-end infrastructure that processes over 3 million items per day.

The current website is a phase 2 responsive MVP built on a PHP framework (Symfony2), utilising modular, re-usable JS components and the TWIG templating engine for re-usable view snippets. Javascript libraries of note; Masonary for the responsive product grids, imageloaded for lazy-loading images, Owl Carousel for the galleries and the conventional jQuery for event handling, DOM shuffling and animations. All website data is sourced from beautifully 'paginate-able' API endpoints; no ugly data retrieval logic/adapters underpinning the web components here. Consequently, the web-project is purely for the purpose of the user and not the storage engine.
