[Job-31203] AI Engineer Master, Brazil

At CI&T, we help large enterprises transform the potential of AI into real business impact with AI Deployment, AI-native execution, and tech-integrated business solutions. With 30 years of experience in technological transformation, we accelerate innovation with expertise in Agentic SDLC, Application modernization, Data & AI, Martech and Business strategy. We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day.

You write the ADRs, you defend them to the client, and you revisit them when they stop being true. Tech Leadership with Your Hands On: Lead the operational team day to day — technical direction, design review, code review, and the architectural decisio
