• Build and maintain backend services and APIs in Python • Design and ship AI features using LLMs and modern ML techniques • Implement retrieval workflows (RAG, embeddings, vector search) • Take AI systems from prototype to production and iterate based on real usage • Work closely with other engineers and stakeholders to make good technical trade-offs • Help keep our systems clean, reliable, and easy to extend

• Design, install, configure, and maintain cloud-based database environments • Monitor database performance and proactively identify and address performance issues. • Ensure the security of the database environment, including access control and data encryption • Develop and implement backup and recovery procedures to ensure the integrity of the database • Plan and execute database upgrades and migrations • Provide technical support to end-users and troubleshoot issues with the database • Automate database maintenance and management tasks where possible • Create as built documentation for database service configurations and options • Stay current with emerging trends and technologies in cloud-based database solutions • Maintain familiarity with infrastructure as code (IaC) and CI/CD pipeline with respect to cloud database offerings. • Collaborate with other team members and stakeholders to ensure the database architecture design meets performance and scalability requirements. • Supporting rigorous project governance and execution achieved through: • Meeting with team members daily to review progress. • Submitting time on assigned projects, daily. • Supporting project delivery team members by: • Always operating with transparency • Being responsive to requests from team members for information • Communicating working preferences and understanding the working preferences of others to help develop a high-performing team that operates with respect, effectiveness, and efficiency. • Specific Responsibilities of the DBE • Designing, implementing, and maintaining databases: The DBE is responsible for designing and implementing the organization's database system, and for ensuring that it is maintained and updated as needed. • Monitoring and optimizing database performance: The DBE must analyze the database system monitoring to ensure that it is performing optimally. This may include identifying and resolving performance bottlenecks, optimizing compute and storage, and provide guidance on poorly performing queries. • Ensuring data security and integrity: The DBE must ensure that the organization's data is secure and that access to the database system is properly controlled. This may include implementing security policies and procedures, configuring user access, encryption at rest and in transit, and managing data backups and recovery. • Providing technical support and vendor escalation: The DBE must provide technical support to end-users of the database system, including troubleshooting issues and providing guidance on how to use the system effectively. The DBE will submit and respond to vendor support cases (AWS and other). • Collaborating with other teams: The DBE must work closely with other teams, such as development, cloud operations and infrastructure teams, to ensure that the database system is integrated with other systems and is optimized for performance.

• Help design, build, and maintain scalable, high-quality web applications. • Work across the entire stack, from modern frontend interfaces to robust backend services. • Collaborate closely with product, design, and other engineering teams. • Design, build, and maintain backend services using Java 17/21 and Spring Boot. • Implement and evolve REST and gRPC APIs following best practices and versioning standards. • Ensure service reliability through unit/integration tests, troubleshooting, and root-cause analysis. • Work with PostgreSQL (schema design, performance tuning) and integrate with caching layers (Redis). • Build and debug containerized services using Docker and deploy them on Kubernetes (GKE). • Apply security fundamentals: OAuth2/OIDC, JWT validation, RBAC, and secure coding practices. • Collaborate with cross-functional teams, ensuring clear communication and ownership of deliverables. • Contribute to CI/CD workflows (Tekton/Jenkins, ArgoCD) and follow GitOps principles. • Participate in technical discussions, design reviews, and mentor team members when needed.

• Atuar em todo ciclo de vida desde a concepção da funcionalidade, acompanhamento de testes, deploy em produção, sustentação e melhoria contínua até a disponibilização de serviços vinculados ao produto de um dos maiores bancos do Brasil.
