Infrastructure Software Engineer, AI & Data Security (Contract, Argentina)

Job description

ABOUT HOMEVISION HomeVision is building the next generation of AI-powered software for the $13 trillion mortgage industry. Our platform, MIRA (Machine Intelligence Review Assistant), automates labor-intensive document processing and underwriting, helping lenders close loans faster and with less friction — ultimately saving borrowers time, money, and stress. We have already transformed appraisal operations for the country's top lenders, cutting review times by over 75%. Now, we are aggressively expanding MIRA to cover the entire loan file — automating income, assets, and credit analysis — to create a holistic underwriting utility for the industry. We look for hungry, smart, curious and kind people who enjoy hard problems and real responsibility. Engineers own meaningful projects end to end, from design to deployment, and collaborate closely with product, design and our go-to-market teams. We value low ego, high ownership, clear communication, and respect for each other's time. We always try to "do the loving thing" in how we work together and with our customers and partners.
