Loop54 Stockholm Heltid

Frontend Developer

Detta jobb är inaktivt och går inte att söka längre.


Loop54 is rapidly becoming a game-changer in the business of e-commerce. This equals a lot of fun, but also a lot of things that need to be built and scaled up, thus we are growing our development team. Do you want to help us build the best product search engine out there?

About the job

At Loop54 we develop a search engine that uses cutting edge AI technology to provide truly relevant search results and that learns from user behaviour to continuously do so. We already deliver search to hundreds of e-tailers and we are adding new ones at an ever quickening rate. To complement our magnificent search engine we are also providing our customers with a login portal where we present useful data and tools. We call this portal Insights, and its purpose is to provide just that, insights into what users are searching for and how they are interacting with the product catalogue. Building the Insights portal is one of the things that we need your help with!

So, what's it like to work at Loop54? We value high degrees of responsibility and autonomy. We strive to work transparently throughout the organisation and we always have a humble approach to questions or feedback from colleagues. We appreciate teamwork, diversity and equality. And, most importantly, we have fun at work!

We're a team of 5 skilled developers and right now we are expanding with more frontend developers. We are primarily working with NodeJS + React for our frontend part, with a backend built in C#. The main applications is a analytics tool (Insights) to better understand the search behavior of people. Your work will primarily be building and improving the Insights portal. You will have a lot of influence over technical decisions and we expect you to contribute actively in the development process.

About Loop54

Founded in Stockholm in 2012, Loop54 started life as a search and recommendation related consultancy project for Voddler (the leading Swedish-based video-on-demand platform at the time). Loop54 morphed into a standalone product search engine in 2013, with the company growing and soon becoming cash-flow positive.

In 2015, Loop54 raised $580K in seed funding from Axel Johnson (one of Sweden's leading business groups, employing 19,000 people, and whose investments engage with 1 million customers daily), RECAPEX (based in Stockholm, previous investments: virtual fitting solution for fashion e-tailers, Virtusize), together with Swedish government agency, ALMI Invest, and angel investor, Erik Byrenius.
