Fullstack Developer - Java + React or Angular | Jersey City, NJ
Job Description
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?

Founded by a Latina engineer from Medellín and based in Tampa, Florida, MAS Global Consulting is a 100% Hispanic and woman-owned company, recognized as a Great Place to Work and one of the Fastest-Growing Companies in the US.
We connect top Latin American talent with North American clients to build digital, data, and cloud solutions. Our teams are currently helping world-leading organizations like JP Morgan Chase, Johnson Controls, and Dell to modernize platforms, deliver innovation, and scale digital transformation.
