• Design, develop and maintain robust integrations via API (REST/SOAP) with webservices from various municipal governments across Brazil. • Architect and optimize batch billing routines, ensuring efficient asynchronous processing, queue handling, resilience to network failures and intelligent retries. • Work extensively with SQL Server databases. Analyze execution plans, optimize heavy queries, create/adjust indexes and ensure the database supports high daily issuance volumes without bottlenecks. • Translate complex municipal tax legislation into application logic and take a leading role in adapting our ERP to new scenarios and the impacts of the Tax Reform on service sales. • Investigate and resolve complex integration issues in production, mapping performance bottlenecks or communication failures with external servers.

• Engenharia de Integrações SEFAZ: Desenvolver, manter e escalar as integrações com os webservices da SEFAZ (autorização, cancelamento, carta de correção, inutilização) garantindo resiliência e estabilidade. • Ciclo de Vida do Produto Fiscal: Arquitetar lógicas robustas para operações complexas, como remessas, devoluções, triangulações e emissões em contingência. • Otimização e Alta Volumetria: Atuar fortemente no banco de dados (SQL Server). Você precisará analisar planos de execução, refatorar queries pesadas e garantir que tabelas de faturamento com milhões de linhas respondam em milissegundos. • Estratégia Fiscal e Reforma Tributária: Codificar o complexo motor de impostos (CST/CSOSN, CFOP, NCM, partilha de ICMS) e ser peça-chave na reestruturação da plataforma para atender aos impactos da Reforma Tributária na circulação de mercadorias (IBS/CBS). • Processamento Assíncrono: Lidar com mensageria e processamento em lote para garantir que gargalos ou quedas nos servidores do governo não travem o faturamento dos nossos clientes.

• Define Enterprise Data Architecture across Fabric, Data Lake, EDW, and analytics platforms. • Design Integration Patterns for ingestion, transformation, and consumption. • Create architectural flows and reference models. • Establish standards for data modeling, metadata, lineage, and governance. • Implement data validation, logging, monitoring, lineage, and RBAC. • Ensure compliance with enterprise security, confidentiality, and regulatory standards. • Drive platform cost optimization, performance tuning, and operational excellence. • Enforce architectural governance and adherence to standards. • Collaborate with business stakeholders and source system teams to understand data requirements. • Translate business needs into technical specifications and architectural roadmaps. • Review user stories and provide architectural guidance to development teams. • Support QA and functional teams in defining testing strategies for new and existing features. • Ensure delivered solutions align with business needs and architectural intent. • Integrate AI/ML Models and GenAI capabilities into data products and workflows. • Evaluate emerging technologies and recommend adoption strategies. • Guide teams on responsible AI usage and integration patterns. • Conduct root cause analysis for data issues and identify opportunities for improvement. • Manage platform reliability, data quality, and governance processes. • Define the continuity strategy for all data and integration platforms, not just implement it. • Proactively identify architectural risks.

• Implement, fix and enhance features in internal systems based on .NET and Angular • Perform preventive and corrective maintenance on existing code, ensuring quality, performance and security • Develop queries in Oracle, MySQL, MongoDB or DynamoDB • Support simple integrations using queues (Kafka, SQS) and S3 storage • Execute basic unit and functional tests • Document code and changes according to team standards • Collaborate with development colleagues and other departments to understand requirements and propose appropriate technical solutions • Support the continuous evolution of systems by suggesting improvements and adjustments • Perform other development-related activities as directed • Perform other related activities
