Senior JavaScript Developer - remote

VITALS
Posted 4 years ago

Do you feel as excited writing beautiful, fancy code in React.js as you would go exploring pure vanilla JavaScript? Do you think that frameworks and libraries are simply tools at our (optional) disposal, more than a lifestyle to live and die for? Do you like to comfortably sleep at night because the code base is fully covered by tests?

We are looking for you! Join our Tech Team at VITALS!

VITALS is such a complex app with so many features that we basically get to play with every single type of technology out there. Just thing about everything that has to go right for an app like the Visitor Replays to actually work!

This is a great opportunity to make substantial impact on our business growth and to have great career perspectives. There's room to grow up in seniority, learn new technologies and even achieve a leadership position around here.

You will experience the support of an experienced team and the freedom to use your technical expertise and initiative to achieve shared goals. This position requires authentic curiosity and will to learn every day. We focus on quality and maintainability of what we do, in order to maximize the company goals in the long term, while executing urgent tasks with surgical precision when needed. We expect strong organizational skills, critical thinking and enthusiasm for achieving company and self-oriented goals.

What we offer

We offer you the opportunity to be part of a team that is not afraid of learning on a everyday basis. You will have the possibility to experiment with new technologies and the freedom to choose your own equipment (high-end Linux or Mac laptops, with UHD external monitors) and software (your favorite IDE or simply Vim if you want).

Our environment is very supportive, where proposals for change and suggestions for improvements are encouraged. In addition, we offer flexible working hours, an informal working environment with flat hierarchy, and competitive salaries. 

As learning is a fundamental part of our style, you can expect to be going to conferences and meetups (when possible), doing workshops and reading books and other technical material in a regular basis.

Skills &Requirements
