What does a JavaScript developer do?

A JavaScript Developer is responsible for designing, developing, and maintaining web applications using the JavaScript programming language. They typically work on both the front-end (user interface) and sometimes the back-end (server-side) of web projects, creating interactive features, optimizing performance, and ensuring cross-browser compatibility. Their role often involves collaborating with designers and other developers to deliver a seamless user experience.

JavaScript/CoffeeScript Engineer

Boxtro Llp 123

San Francisco, CA • On-site

Full-time

Re-posted 3 days ago

Job description

First things first, you will focus on the modern web - We don't support IE10 and less, so you'll never have to worry about them!

Most of our code is written in CoffeeScript front- and back-end.

We're an open-source driven startup and we contribute back to the community. We continually push new products/frameworks and maintain the ones that we're the authors/users of.

All engineers on the team contribute to full stack feature development as well as improving our open source projects, including KD (http://github.com/koding/kd), Kite (http://github.com/koding/kite).

We're looking for engineers with deep JavaScript expertise and interest to participate on our open-source projects.

Ok, sound good?

This job could be described as Front-End Developer, but it is not because you must be a _damn_ good software engineer first.

Hope to see you at KodingHQ.
