[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.

We are not looking for an architect who reviews what agents produced.

You will own the architecture across workstreams — the multi-account AWS landing zone (Network, Shared Services, and Workload Non-Prod and Prod), the application architecture running on top of it, and the platform architecture that comes next.

You will also lead the operational team as tech lead: setting the technical direction, unblocking engineers, and shipping code yourself. This is a hands-on role. The person who owns the diagram is the person who writes the CDK.

Responsibilities

Architecture Ownership: Own the AWS enterprise architecture end to end — multi-account governance and guardrails, Transit Gateway topology, hybrid connectivity to on-premises data centers, centralized traffic inspection, hybrid DNS, and the security posture that holds it all together.

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
