[Job-29470] Master AI Developer, Brazil

May 26, 2026

We are tech transformation specialists, uniting human expertise with AI to create scalable tech solutions.With over 8,000 CI&Ters around the world, we’ve built partnerships with more than 1,000 clients during our 30 years of history. Artificial Intelligence is our reality. We are looking for a Master AI Developer who views Artificial Intelligence not just as a tool, but as a catalyst for redefining how software is built. In this pivotal role, you will be responsible for the entire lifecycle of new features using AI agents—from refining high-level requirements to building the underlying infrastructure, deploying, and monitoring. You will also ensure that all squads understand and can effectively utilize these pipelines. Key Responsibilities - End-to-End Ownership: Analyze and refine high-level business requirements, transforming them into robust technical architectures. - AI Orchestration & Evolution: Design, develop, and evolve AI agents and frameworks that automate complex workflows. You are expected to keep these agents "alive" and improve them. - International Collaboration: Act as the primary technical point of contact for international clients. Advanced/Fluent English is non-negotiable. - Full-Stack Engineering: Build, maintain, and scale the backend and frontend components that house your AI solutions. - Automated Reliability: Implement comprehensive testing automation and manage CI/CD pipelines to ensure high-velocity, low-risk deployments. - Innovation & Productivity: Proactively research and propose new tools, frameworks, and methodologies that can accelerate team productivity and product performance. Required Qualifications - Proven Full-Stack Experience: Significant experience in professional software development. You should be equally comfortable in the Backend (Java, Spring Boot / Python / Node.js), Frontend (React), Database (PostgreSQL), microservices architecture and event driven services (Kafka, EventHub). - DevOps & Automation: Hands-on experience with CI/CD pipelines (Jenkins, AzureDevOPS Pipelines.), containerization (Docker/Kubernetes), and cloud infrastructure in general (specially Azure). - Testing: Expertise in automated testing frameworks (Unit, Integration, E2E) specifically applied to non-deterministic AI outputs. - AI Expertise: Deep experience with LLMs, RAG (Retrieval-Augmented Generation), prompt and context engineering, and multi-agent systems (MAS). - Agentic Frameworks and tools: Proven experience with frameworks like LangChain, CrewAI, AutoGen, or similar tools like Claude Code and Codex for building autonomous agents. - Agile Mindset: Comfort leading in a fast-paced, iterative environment where the "dedicated cell" model thrives. Our Mindset We don’t want someone who just follows a ticket. We want an architect of productivity. You should be a seasoned engineer who understands that an AI agent is only as good as the pipeline it runs on. If you are the type of developer who constantly asks, "How can we use an agent to do this faster?" while ensuring the CI/CD remains green, you are the one we are looking for! #LI-LO1 Our benefits: -Health and dental insurance-Meal and food allowance-Childcare assistance-Extended paternity leave-Partnership with gyms and health and wellness professionals via Wellhub (Gympass) TotalPass;-Profit Sharing and Results Participation (PLR);-Life insurance-Continuous learning platform (CI&T University);-Discount club-Free online platform dedicated to physical, mental, and overall well-being-Pregnancy and responsible parenting course-Partnerships with online learning platforms-Language learning platformAnd many more!
