📋 Description

• You will architect and evolve the datalake that is the company's data nervous system — the foundation that feeds, in real time, the dynamic pricing engine, ML models, and the group's business intelligence. • This is an ownership role: you define the multi-tenant Lakehouse architecture, from streaming to the semantic layer, and are responsible for its reliability, governance, and cost. • Design and evolve the data lake on Apache Iceberg over S3 — well-defined layers, partitioning and compaction, time-travel and support for DELETE/UPDATE for LGPD (Brazilian data protection law). • Build real-time ingestion (Kafka, Flink, CDC with Debezium) with controlled schema evolution (Schema Registry) and delivery guarantees. • Model the transformation layer in dbt and orchestrate batch and quality flows in Airflow, from crawler to backfill. • Maintain metric definitions in Cube.js — the single source that feeds BI and AI agents and ensures consistency across the company. • Operate federated and low-latency OLAP queries over the lake, with cost and access isolation by tenant and performant queries. • Ensure data testing, lineage and cost efficiency, keeping the platform reliable as it scales.

🎯 Requirements

• Strong command of SQL and query optimization in distributed environments (Minimum 5 years). • Python with solid experience in PySpark or distributed processing. • Orchestration (Airflow), ELT and dbt applied at scale (Minimum 4 years). • Streaming (Kafka, Flink) and Lakehouse architectures with Apache Iceberg (Minimum 3 years). • Strong understanding of data governance, quality, and modeling. • Comfortable with AI-assisted development (e.g., Claude Code). • CDC (Debezium) and low-latency OLAP (ClickHouse, Pinot, Trino/Athena). • Semantic layers (Cube.js, dbt) and Data Mesh architectures. • Governance and catalog tools (OpenMetadata, Lake Formation). • Vector databases (Qdrant) and data pipelines for ML.

🏖️ Benefits

• Remote work • Project duration: 6 months, with possibility of extension or conversion to permanent employment.
