Hey everyone This is Thai Viapiana from CI&T's Talent Attraction Team :) We are looking for a Technical Architect to lead the migration to a modern data platform built on Snowflake, dbt, and Prefect. The foundation is in place—now we need an architect to guide the transformation from the existing platform while redesigning processes to meet evolving business needs.
The Challenge: You'll be the technical architect guiding this transformation. Define how data moves to the new platform, redesign workflows for modern architecture, and ensure the business keeps running throughout the transition.
Your Role: You'll be the technical reference for this platform evolution For that, you'll need: Design the Migration Approach: Define how to transition from the existing platform to Snowflake while maintaining business operations. Redesign Data Processes: Transform current workflows into modern, scalable patterns using dbt and Prefect. Establish Technical Standards: Create patterns and best practices for the new platform. Support Business Needs: Balance migration work with delivering new capabilities the business demands. Optimize and Scale: Design for performance, cost efficiency, and growing data volumes. Guide the Engineering Team: Mentor engineers on modern data practices and architectural thinking. Enable Velocity: Build frameworks and reference implementations that accelerate migration and development.
This is an architecture and leadership role. You'll be hands-on when needed—building migration patterns, solving complex technical challenges, creating proof-of-concepts—but your primary value is architectural vision and strategic technical direction.
Required: 5-7+ years in data engineering with experience in architecture or technical leadership. Snowflake expertise - Production experience with architecture, performance optimization, and cost management. dbt proficiency - Advanced modeling, testing strategies, and transformation patterns. Orchestration experience - Prefect, Airflow, or similar tools for workflow design. Python skills - Building reusable frameworks and components. Migration thinking - You understand how to move systems while keeping the business running. Advanced English - Daily collaboration with US-based stakeholders and technical presentations.
Ideal: Experience leading data platform migrations or modernization initiatives. Strong understanding of dimensional modeling and modern architecture patterns (medallion, lakehouse). CI/CD for data pipelines (Git workflows, automated testing, deployment automation). Data governance and quality frameworks. Ability to balance technical debt, new development, and business priorities.
Why This Matters: Strategic Transformation: Lead a critical platform migration with business impact. Modern Technology: Work with Snowflake, dbt, Prefect, and Python stack. Architectural Authority: Your decisions shape how the new platform works. Complex Challenge: Balance migration, redesign, and new business requirements simultaneously. Career Defining: Showcase a project demonstrating migration leadership and architectural thinking. Autonomy: Define the approach, establish standards, and make key technical decisions.
About the Engagement: Work Model: Fully remote from Brazil. Collaboration: Regular engagement with US-based business and technical stakeholders. Scope: Migration planning and execution, process redesign, ongoing platform evolution.
