Job Description

About Us

What if there was an easier way to turn site visitors into customers, increase customer conversions and enhance revenue without having to analyse copious amounts of data?

Cloud IQ is a conversion rate optimisation platform seeking to do exactly that for ecommerce operators. The mission is "to level the ecommerce playing field" by developing tools within the budgets of organisations of all sizes. The company was named one of London's most visionary digital companies in last year's Digital Innovators Power List, produced by City A.M.

Our founders, James and Paul, are proven technology innovators. Their close working partnership stretches back 15 years, creating their first business during the fallout of the infamous dotcom crash — and defying the industry climate to create software appreciated by clients in well over a dozen different markets.

Headquartered at RocketSpace, next to Angel station in Islington in North London, we also have offices in Sydney, Madrid and Cardiff.

With recent investment from PayPal in the Summer of 2017, we have an exciting vision for the future. We are very proud of our team at Cloud IQ. We promote a culture that fosters creativity and innovation at every step and are dedicated to providing the best customer experience for our clients and end users. We help each other and we use the latest technology and agile working practices to constantly improve and learn.

Who are we looking for?

You will be a talented mid/senior level UI developer who will join one of our London-based agile development teams and work on the evolution of our our industry-leading Conversion Rate Optimisation platform.  You will be joining a growing, maturing team and who has a passion for developing customer-centric products.

You will have excellent technical abilities, outstanding problem solving skills, be a great communicator, have the ability to self-organise in a high performance culture, and demonstrate a keen interest in modern technologies and best practices. A self-starter with a strong sense of ownership and drive is a must.
