• Develop backend services by translating product stories into well-crafted technical solutions, with autonomy to drive deliveries from start to finish. • Contribute to product architecture discussions by raising questions and proposing alternatives, even when the initial design comes from more senior team members. • Estimate effort and assess risks for tasks you take on, based on technical investigation before committing. • Implement integrations with third-party APIs based on technical documentation, paying attention to failures, retries, and idempotency. • Collaborate with the team to model data, translating business rules into entities, relationships, and schema evolution. • Write queries and implement data access with attention to performance and transactional consistency. • Document APIs for consumption by a decoupled frontend and other integrators. • Write automated tests (unit and integration) as part of the development flow, not as an optional step. • Ensure observability of delivered features and participate in investigating production incidents. • Participate in code reviews with a collaborative attitude, reviewing peers' code and responding constructively to feedback. • Communicate clearly with the Tech Lead, PO, designers, and analysts to refine stories, clarify questions early, and propose simpler approaches when appropriate. • Monitor what you delivered in production, validating whether observed metrics match expectations. • Seek to understand the business domain to make technical decisions aligned with real user impact, rather than simply executing what's written on the ticket.

• Develop and enhance microservices using Java 21 and Spring Boot • Design and implement asynchronous workflows using event-driven messaging • Ensure data integrity, traceability, and auditability • Develop and maintain frontend applications using React + TypeScript • Build integrations between APIs and internal/external systems • Implement automated tests and ensure coverage of critical scenarios • Maintain and evolve CI/CD pipelines and Kubernetes environments • Participate in code reviews and architecture discussions • Work with a focus on scalability, reliability, and clear separation of concerns

• Design, develop and implement robust, scalable software solutions using Java; • Develop, optimize and maintain robust, scalable RESTful APIs; • Design and implement microservices-based solutions; • Collaborate with cross-functional teams to understand project requirements and translate them into technical solutions; • Troubleshoot and resolve complex performance and security issues; • Perform code reviews, identify areas for improvement and ensure adherence to coding standards; • Work with software architects to define standards and best practices; • Support and mentor junior and mid-level developers, fostering a continuous learning environment; • Contribute to building business-applied Artificial Intelligence solutions, including integration with AI APIs, data processing for insight generation, automation of analyses, and development of features based on predictive or generative models—always ensuring scalability, optimization, security and integration with the microservices architecture.

• Act as the technical reference for development teams and enabling teams/departments. • Participate in vendor meetings, validating the technical feasibility of proposed solutions. • Create and maintain technical documentation that explains the patterns and technologies used within the company. • Help connect enabling teams and development tribes. • Create technical architecture diagrams and designs. • Define the technologies to be used and evaluate new tools. • Define domain models. • Present architectural definitions and lead the technical team on implementation decisions. • Follow best practices by applying architectural patterns. • Guide teams to follow best practices for scalability, elasticity, and security. • Orchestrate responsibilities and end-to-end implementation across the teams involved. • Disseminate knowledge through workshops, study groups, etc. • Review implementations to identify potential technical debt. • Participate in defining solution and business architecture together with other business architects, product owners, etc. • Assist teams with troubleshooting and resolving production issues. • Build solutions that leverage Artificial Intelligence applied to the business.
