Descrição da oferta de emprego

Hi, this is Monica Hernandez, Founder and CEO of MAS Global. I started MAS with the idea that we could be more than a business, that’s why we like to say that MAS is More.

I was born and raised in Medellin, Colombia and thanks to a scholarship I became a Software Engineer and built a career in the US, where I now live. Starting MAS was my way to give back to the community, building a bridge between the US and Colombia and rest of Latin America, while creating opportunities in technology for other women, latinos and minorities across the globe.

Join our team for exciting opportunities with large scale projects, to experience a multicultural environment with more than 10 nationalities, all united by the same values.

We are All-In for our clients and our people, we live collaboration so we like to say Juntos Somos MAS, we care about community impact and helping each other (we have a Foundation!), we love providing a positive MAS experience to those we touch, and we stay curious so we are in constant learning and knowledge sharing mode.

Vamos por MAS?
