We are looking for a profile proficient in the Java/Kotlin/React ecosystem who has already integrated AI tools (such as GitHub Copilot, Cursor, or ChatGPT) into their workflow to accelerate code writing, test creation, and documentation, without sacrificing technical rigor and critical analysis.

Investigate and resolve performance, stability, and incident issues in distributed environments;
Conduct root cause analyses and contribute to continuous improvements in monitoring and service reliability;
Actively participate in technical and functional refinements, assessing risks and proposing solutions;
Collaborate with the team through code reviews, pair programming, and knowledge sharing, and support less-experienced developers in adopting best practices and development patterns;
Contribute to building secure, resilient, and scalable systems, and investigate and resolve complex technical issues in distributed cloud applications;
Monitor and remediate vulnerabilities, ensuring compliance with security standards;
Use AI development tools as productivity aids while maintaining critical review of the solutions they generate.
