Importante : se você reside na Região Metropolitana de Campinas, sua presença nos escritórios da cidade será obrigatória, conforme a política de frequencia vigente.
Nosso cliente está conduzindo uma modernização massiva de seus pipelines de dados, migrando cargas de trabalho legadas em Databricks para uma nova arquitetura nativa no Google Cloud. Esta posição é central para essa transformação: o profissional atuará como um dos pilares hands-on da refatoração, transformando lógicas complexas de processamento distribuído em padrões modernos de ELT, sem comprometer a continuidade das integrações já existentes.
O Data Developer Senior atua na conversão direta de notebooks legados, na construção de pipelines de ingestão escaláveis e na garantia de que a arquitetura em camadas (Raw, Trusted Core e Gold) preserve os contratos de dados que sustentam sistemas e dashboards em produção. O papel combina profundidade técnica na reengenharia de código acoplado com colaboração próxima aos times de negócio para validar cada etapa da migração.
Responsibilities:
Code Refactoring : Translates legacy Databricks notebook logic into modern ELT patterns, prioritizing declarative SQL-based transformation for standard cases and developing Python-based distributed processing routines for intricate logic (such as RDD-based operations).
Data Contract Preservation : Ensures backward compatibility during migration by implementing trusted-core layering and reverse-view strategies, preventing breaking changes for downstream consuming systems and dashboards.
Ingestion Pipeline Development : Builds scalable ingestion pipelines by parameterizing YAML configurations that feed an automated DAG generation pipeline, orchestrated through a workflow scheduler and consuming standardized processing templates.
Data Quality Implementation : Applies synchronous and unit-level assertions within the transformation layers to prevent null values, enforce key uniqueness, and validate domain conformity.
Migration Validation : Executes technical validation projects by reconciling data output between the legacy environment and the new platform, confirming record-level and field-level parity ("cara-a-crachá" checks).
GitOps Development : Follows strict CI/CD workflows through feature branches, pull requests, and automated deployment pipelines to development and production environments.
Cross-Team Alignment : Collaborates consultatively with business Data Stewards to align integration dependencies, negotiate refactoring scope, and validate migrated outputs side by side with stakeholders.
Requirements:
Strong, hands-on technical depth in Python, PySpark, and advanced SQL for large-scale distributed data processing
Robust experience migrating data lakes and refactoring legacy code, including reverse-engineering tightly coupled logic (such as Databricks or Azure Data Factory pipelines) into modular cloud-native components
Practical mastery of the Google Cloud data engineering ecosystem, particularly BigQuery, Dataform, and Dataproc Serverless
Solid understanding of Medallion Architecture (Raw/Bronze, Silver/Trusted Core, Gold) and analytical data modeling strategies, including Star Schema and One Big Table approaches
Hands-on experience with modern GitOps development flows (code review, pull request submission) and orchestration automation using Airflow/Composer
Maturity in data quality practices, with testing applied directly to transformation pipelines
Consultative, collaborative communication style to align cross-team dependencies, negotiate refactoring scope, and validate outcomes alongside business Data Stewards
Nice to Have:
Experience applying Generative AI agents (such as Gemini, Vertex AI, or Claude) to automate PySpark-to-SQL code refactoring, dependency graph analysis, or automated documentation generation
