This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Java Software Development Engineer based in Brazil.

This role offers the opportunity to contribute to a high-impact transaction systems platform supporting critical card authorization and clearing processes. You will design, develop, and maintain scalable cloud-native applications using Java, Kafka, APIs, caching, and modern infrastructure technologies. The position combines hands-on software engineering with reliability, performance, and operational excellence in high-throughput environments. You will work within an agile and collaborative engineering team where ownership, code quality, and continuous improvement are highly valued. The environment encourages engineers to learn new technologies and move confidently across different technical stacks. Your work will directly contribute to reliable, secure, and scalable payment technology used in complex business environments.

• Develop, implement, and maintain scalable and reliable software solutions using Core Java, Kafka, caching technologies, APIs, and other modern engineering tools.
• Build and evolve cloud-native applications supporting high-throughput transaction processing, with a strong focus on reliability, scalability, maintainability, and operational performance.
• Write clean, maintainable, well-documented code that follows established engineering standards and contributes to a sustainable software architecture.
• Participate actively in code reviews, collaborating with other engineers to identify improvements, maintain coding standards, and ensure consistently high-quality implementations.
• Troubleshoot production and development issues efficiently, using application logs, metrics, traces, and other observability tools to identify root causes and restore reliable service.
• Work with containerized environments and orchestration technologies to support the deployment and operation of modern cloud-based applications.
• Contribute to event-driven architectures using Kafka and develop solutions involving distributed caching technologies such as Redis or Valkey.
• Continuously learn and adopt new technologies, adapting across different technology stacks and contributing to the evolution of engineering practices and solutions.
• Stay current with software engineering best practices, emerging technologies, and industry trends, bringing relevant improvements and ideas to the team.

• Bachelor’s degree in Computer Science, Engineering, or a related technical field, combined with strong professional experience in software development and production systems.
• Solid software engineering experience, including the development and support of cloud-based applications and infrastructure-as-code environments.
• Strong understanding of data structures, algorithms, object-oriented design, software engineering principles, and structured problem-solving.
• Hands-on experience designing, implementing, and operating caching solutions such as Redis or Valkey in cloud-based, high-throughput systems.
• Experience with Docker and container orchestration technologies such as Kubernetes for application deployment and operational management.
• Practical experience with event-streaming platforms such as Apache Kafka and an understanding of event-driven architectures and distributed systems.
• Experience working with cloud platforms such as AWS and familiarity with cloud-native application development and operational practices.
• Experience using logging, metrics, tracing, and observability tools such as Grafana or Splunk to monitor, diagnose, and troubleshoot live production systems.
• Strong written and verbal communication skills, with the ability to collaborate effectively within an agile, multidisciplinary engineering environment.
• Familiarity with API development and/or gRPC services is considered an advantage.
• Experience with automated deployment pipelines and modern CI/CD practices is a plus.
• Contributions to open-source projects or personal technology projects demonstrating curiosity and technical initiative are valued.
• A genuine passion for technology, continuous learning, and professional growth is highly desirable.

• Fully remote opportunity based in Brazil, providing flexibility to work from home.
• Opportunity to work on high-throughput transaction systems and technically complex cloud-native applications.
• Hands-on exposure to modern technologies including Java, Kafka, Redis or Valkey, Kubernetes, Docker, AWS, APIs, and observability platforms.
• Opportunity to develop expertise in distributed systems, event-driven architectures, cloud engineering, and scalable transaction processing.
• Collaborative and agile engineering environment that values ownership, high-quality results, knowledge sharing, and continuous improvement.
• Comprehensive and market-competitive benefits designed to support personal and professional well-being.
• Opportunity for continuous learning and career growth while working with evolving technologies and modern engineering practices.
• Inclusive workplace committed to diversity, equal opportunity, and a respectful environment for professionals from different backgrounds.
