Qualificações

• Bachelor's degree in Computer Science, Software Engineering, or related field.
• 8–10 years of professional software engineering experience.
• Strong expertise in Java and Spring Boot for building enterprise-grade backend applications.
• Experience designing and developing RESTful APIs and distributed microservices.
• Strong understanding of OO design, data structures, algorithms, and software design principles.
• Experience with PostgreSQL or other relational databases, including schema design, query optimization, indexing, and transaction management.
• Experience building scalable, secure, highly available, and fault-tolerant distributed systems.
• Strong understanding of authentication/authorization, API security, OAuth2, JWT, and secure software development practices.
• Experience with asynchronous messaging technologies such as Kafka, RabbitMQ, or similar event-driven platforms.
• Familiarity with caching technologies such as Redis and distributed caching strategies.
• Experience with CI/CD pipelines, automated testing, code quality tools, and modern software delivery practices.
• Understanding of observability technologies including logging, metrics, tracing, monitoring, and alerting.
• Experience collaborating with mobile engineering teams and designing APIs optimized for iOS and Android applications.

Responsabilidades

• Design, develop, and maintain scalable, secure, and high-performance backend services using Java, Spring Boot, PostgreSQL, and REST APIs.
• Architect and build distributed microservices that are resilient, observable, and easy to maintain.
• Design REST APIs that enable seamless integration with mobile applications, web applications, and external partner systems.
• Lead architecture and system design discussions, producing high-quality design documents and driving alignment across engineering teams.
• Optimize database design, queries, indexing strategies, and transaction management to improve performance and scalability.
• Develop comprehensive automated testing strategies, including unit, integration, contract, performance, and load testing.
• Improve application reliability by implementing observability, logging, distributed tracing, health monitoring, and alerting.
• Identify technical debt, scalability bottlenecks, and reliability risks, and drive continuous platform improvements.
• Build and enhance CI/CD pipelines, deployment automation, infrastructure automation, and engineering productivity tools.
• Partner closely with Product, Mobile, Web, Security, Infrastructure, and DevOps teams to deliver high-quality customer experiences.
• Lead code reviews, mentor engineers, establish engineering best practices, and raise the overall quality bar across the organization.
• Troubleshoot complex production issues, perform root cause analysis, implement corrective actions, and improve operational excellence.
• Evaluate emerging technologies and architectural approaches, providing technical recommendations based on business and engineering needs.
• Create and maintain technical documentation including architecture documents, API specifications, runbooks, operational guides, and readiness plans.
• Design highly available services with resilience patterns including retries, circuit breakers, caching, rate limiting, and graceful degradation.
• Drive cross-functional initiatives as a technical lead or STO, helping unblock teams and ensuring successful delivery.
• Gain hands-on experience with automation and AI-assisted software engineering solutions.
