Back-End Engineer (Java-Spring)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Back-End Engineer (Java-Spring) based in Brazil.

This is an opportunity to contribute to a high-impact international project focused on scalable, production-grade backend applications and AI-powered capabilities. You will design and develop robust microservices and REST APIs using Java and Spring Boot, while working with modern cloud technologies. The role combines backend engineering with hands-on AWS, Docker, and Kubernetes experience in a fast-paced, collaborative environment. You will also integrate production-grade Large Language Models into backend workflows, helping bring intelligent features into real-world products. End-to-end ownership is central to the position, from architecture and development through deployment, monitoring, and production troubleshooting. You’ll collaborate with cross-functional teams across LATAM and internationally, with daily communication conducted in English. This is a fully remote contractor opportunity with consistent alignment to Central Time (CT).

Accountabilities:: Design, develop, maintain, and continuously improve robust backend applications and RESTful APIs using Java and the Spring Boot framework.

Build and evolve scalable microservices architectures, applying sound engineering principles to deliver reliable and maintainable production systems.

Deploy, manage, and scale backend services on AWS using Docker and Kubernetes for containerization and orchestration.

Integrate production-grade Large Language Models, including technologies such as Claude, OpenAI, or Gemini, into backend workflows and intelligent product features.

Design and manage data layers using both SQL and NoSQL technologies, ensuring performance, reliability, and scalability.

Take end-to-end ownership of features, guiding them from architecture and implementation through deployment, monitoring, troubleshooting, and production debugging.

Collaborate with cross-functional and international teams to deliver high-quality software while maintaining strong standards for architecture, testing, reliability, and maintainability.

Contribute to technical documentation and effective communication in English across development activities, meetings, and project documentation.

Participate in an agile development environment, contributing to ceremonies, stand-ups, technical discussions, and collaborative problem-solving.

Apply modern distributed-systems practices, with opportunities to work with event-driven architectures, distributed transaction patterns, and advanced AI capabilities.

Requirements

4–7 years of hands-on professional experience developing production-grade backend applications, ideally at a Software Engineer II level or equivalent.

Strong expertise in Java and Spring Boot, with proven experience designing and implementing robust REST APIs.

Practical experience working with both SQL and NoSQL databases, including designing data layers for scalable applications.

Proven experience deploying and managing backend services on AWS, with hands-on knowledge of Docker and Kubernetes.

Direct experience integrating production-grade AI models or Large Language Models such as Claude, OpenAI, or Gemini into software applications.

Demonstrated ability to own features throughout their complete lifecycle, including deployment, monitoring, troubleshooting, and production debugging.

Strong understanding of backend engineering principles, microservices, system reliability, testing, and scalable software architecture.

Fluent English, with excellent written and verbal communication skills for daily technical collaboration, documentation, and meetings.

Strong problem-solving, ownership, collaboration, and communication skills, with the ability to work effectively in distributed and cross-functional teams.

Experience with distributed transaction patterns such as Saga and Transactional Outbox is a plus.

Experience with event-driven architecture and message brokers such as Kafka or RabbitMQ is desirable.

Familiarity with Cucumber, Behavior-Driven Development (BDD), and automated testing is an advantage.

Experience building autonomous AI agents is considered a strong plus.

Availability to consistently overlap with teams working in Central Time (CT), including participation in key ceremonies, stand-ups, and collaborative sessions during standard Austin business hours.
