<div><p><b>Senior Full-stack Software Engineer</b><br>
Remote / Hybrid / On Site (Gouna, Red Sea, Egypt)<br>
<br>
Kalakso is hiring <b>Senior </b>Full-stack Software Engineers for a global AdTech Digital Out Of Home (DOOH) company primarily focused on physical convenience and grocery retailers. We enable retailers to enroll their media inventory into our Retail Media Network, and we make it easy for brand advertisers to publish their marketing campaigns.<br>
<br>
<b>The problem we&rsquo;re solving</b><br>
<br>
Digital retailers use data to study shoppers&rsquo; online behavior, predict their needs, and eliminate any friction points in the decision-making process. As a result, they provide shopping journeys that are very low on cognitive stress and therefore high on conversions/revenue. The problem is that digital-born retailers are moving to the offline world to increase their market share, and physical retailers are lacking the technology to compete with the complex data models digital ones have.<br>
<br>
<b>Our Vision</b><br>
Our vision is to make physical spaces as intelligent and engaging as digital ones.<br>
<b>Our Mission</b><br>
Our mission is to harness the power of data, AI, and Machine Learning by instantly and intelligently delivering highly engaging, personalized, and profitable in-store experiences.</p><div><br>

Our Values</b><br>
<ul><li>Proactive: We don&rsquo;t wait to be told what to do.

</li><li>Diverse: Our differences make us stronger as a group, and we love that.
