Desenvolvedor Full Stack Java/React - Sênior

• Participate in platform architecture decisions, document technical rationale, and contribute informed recommendations to engineering discussions.

• Design, develop, and maintain end-to-end features using Java for backend development and React for frontend applications.

• Implement synchronous and asynchronous integration layers to support reliable communication between services and external systems.

• Build and maintain microservices that integrate with legacy platforms and monolithic applications.

• Model, develop, and optimize data persistence solutions using relational and non-relational databases.

• Implement messaging and asynchronous processing workflows using appropriate technologies and architectural patterns.

• Write and maintain automated tests, participate in code reviews, and uphold software quality standards.

• Investigate, troubleshoot, and resolve issues in production environments, improving system stability and performance.

• Use AI-assisted development tools effectively, critically review generated code, and apply sound engineering judgment to ensure correctness, security, and maintainability.

• Integrate third-party APIs and ensure reliable data exchange across connected systems.

• Collaborate closely with a small, cross-functional team, sharing technical context and supporting the development of less experienced colleagues.

• Balance technical quality with delivery priorities, contributing to continuous improvement and practical engineering solutions.

Requirements

• Strong professional experience in software development, including responsibility for applications and features deployed to production.

• Advanced hands-on proficiency in Java for backend development and React for frontend development, with the autonomy to deliver across both areas.

• Experience with Docker and containerization, plus familiarity with deploying applications to Microsoft Azure.

• Strong knowledge of relational databases, including data modeling, querying, and performance optimization.

• Practical experience with asynchronous processing and messaging technologies such as RabbitMQ, Amazon SQS, Amazon SNS, or Apache Kafka.

• Experience with non-relational databases and the ability to assess when they are appropriate for specific use cases.

• Daily experience with AI-assisted software development tools such as Claude Code, GitHub Copilot, Cursor, or equivalent solutions, including the judgment to recognize when AI accelerates development and when its output requires correction or should not be used.

• Experience consuming and integrating third-party APIs.

• Strong problem-solving skills, with the ability to work independently, overcome technical blockers, and seek support when appropriate.

• A quality-focused mindset that balances technical rigor with practical delivery timelines.

• Excellent collaboration and communication skills, particularly in a small-team environment where shared context and close coordination are essential.

• Genuine curiosity about applying AI to product development and improving engineering workflows.
