Software Development


2015-07-22 07:46


We are a team of distributed software developers focusing on exciting challenges of voice, video and text: real-time communications. We are Mojo Lingo: Voice Applications that Work Like Magic.

At Mojo Lingo, the focus of everything we do is communications. Communications underlie everything humans do: every new idea that spread, every magnificent cathedral built, every successful revolution happened because the team behind it communicated effectively. Our mission is to bring seamless, contextual, powerful communications to the world.

We are seeking an experienced Web Front End Developer to join our team creating these applications. As a remote position, you will be largely autonomous, and depend on instant messaging and screen sharing for collaboration. In particular, we’re looking for someone who is a strong problem-solver and relishes a challenge in wrangling ambitious features and vanquishing complex bugs. Each person on our team is empowered to make decisions and enjoys great latitude in choosing the right tools and method for the job.

When we say “Front End” we are primarily looking for someone who can use the great power of JavaScript and Ruby on Rails to create interactive and ultimately usable web applications. The skills we think you’ll need the most are JavaScript (experience with frameworks like React, Angular, Ember or similar is required, but we’re looking for someone who is flexible), as well as experience delivering applications with Ruby on Rails. Obviously you should also be strong with HTML and CSS. If you’re not a great designer, not to worry. We’re more concerned about someone who can deliver the function over the form.

From the beginning we have been a distributed team, with headquarters in Atlanta, but our team members are located around North America, South America, and Europe. We build tools that enable people to communicate fluidly across a wide range of devices, technologies and physical spaces. We are known as application developers and often use technology like speech recognition, text-to-speech, Voice over IP (telephony and non-telephony), instant messaging/text chat and everything to do with the Web.

If you enjoy delighting people by making computers do unexpected things, all while solving complex, technical challenges in a unique industry, come join us!
