Who We Are

MAS means More in Spanish, so MAS Global’s name reflects our mission to create education opportunities for women and Latinos in tech, just like the scholarship ANDI- EAFIT that made our Latina Founder’s story possible, from a low-income neighborhood in Medellin to becoming top 100 Hispanic in Tech in the US.

Based in Tampa, Florida with a strong presence in Colombia, Argentina, and across LATAM, we give our clients in North America access to onshore and nearshore tech talent, to build digital pods or deliver projects to help drive innovation, from Full Stack Software Engineering and Digital/Cloud Modernization to a growing practice on Data Engineering and AI.

Our future is bright, enabled by a diverse group of experts representing 10 nationalities, fresh talent like you, and a solid foundation on decade-long proven results with recognized corporations like Johnson Controls, JPMorgan Chase, and Dell.

MAS is a 100% Hispanic and women owned company and has been recognized with many awards and certifications, like Great Place to Work and fastest growing company in the US.

Required Qualifications

• 5+ years of experience in functional software testing within an Agile environment, with a strong focus on backend and API validation.
  
  
• Deep understanding of the Software Testing Life Cycle (STLC), test case design, and defect tracking in complex enterprise environments.
  
  
• Proven ability to analyze business and technical requirements, translating them into backend/API test strategies, and following stories from analysis through implementation.
