Full Stack Developer

R&D, Tel Aviv

We're looking for a full stack developer who not only loves JavaScript but also has the passion, knowledge and ability to use it in ways that push the envelope of what can be done on the web. 

We use JavaScript for (almost) everything. This means server side, cli tools, webapps and other clients such as mobile, Xbox, Steam and smart TVs apps.

You’ll be working on a platform that enables creation and delivery of experiences that are somewhere between TV shows and video games. You’ll be serving millions of viewers. You’ll be taking JavaScript to the extreme. This means getting to the bits and bytes of rendering, I/O handling and data processing. You’ll be using cutting edge and experimental features. You’ll be facing the darkest corners of modern browsers and nodejs. You’ll be amazed by what can be done in JavaScript these days. It’s going to be fun.

Yes, we use all the tools and libraries cool kids like (React, Redux, Angular, HapiJS to name a few...), but this shouldn’t be your reason for joining us. You’re invited if you are excited as we are about leveraging JavaScript to create the next generation medium of storytelling.

Check out our website (helloeko.com) and the developers website (developer.helloeko.com) to get a sense of what it’s is all about.
