We're seeking developers located in LATAM with at least 5+ years of experience in software development, a strong foundation in object-oriented design, and hands-on expertise building and testing RESTful APIs. If you’re driven by impactful work, committed to quality, and eager to contribute to end-to-end development, this is your opportunity to shine.

What You’ll Do

• Design, develop, and maintain full stack applications using Java (Spring Boot) and React.

• Build and optimize RESTful APIs for scalable integration between services.

• Contribute to database design and development using Oracle, including PL/SQL and performance tuning.

• Implement best practices in code quality, unit testing, and security, including use of tools like JUnit, Maven, Git, and static code analysis.

• Collaborate with cross-functional teams to translate requirements into technical solutions.

• Participate in CI/CD processes using tools such as Jenkins, Datadog, and/or Splunk.

• Work in Linux-based environments and contribute to application stability and monitoring.

What You’ll Bring

• 5+ years of software development experience in full stack environments.

• English proficiency – C1 level or above.

• Strong Java programming skills, including Collections, Lambdas, Functional Programming, and robust error handling.

• Proven experience with Spring Boot, Spring MVC, and the development of scalable RESTful APIs.

• Solid front-end development experience using React, including component lifecycle, hooks, and modern JavaScript (ES6+).

• Familiarity with state management libraries like Redux, and the ability to build responsive, accessible UI components.

• Understanding of front-end build tools, bundlers (e.g., Webpack), and debugging in browser-based environments.

• Good design sensibility and the ability to collaborate with UI/UX teams to implement user-friendly interfaces.

• Proficiency in object-oriented design and common design patterns (e.g., Singleton, Factory).

• Experience working with JSON, XML, and SOAP data formats using Java-native capabilities (JAXP, DOM, etc.).

• Hands-on experience with Oracle databases, PL/SQL, stored procedures, and advanced SQL optimization.

• Familiarity with unit testing (JUnit), automated regression testing, and CI/CD pipelines.

• Working knowledge of Git, Maven, and centralized logging tools like Datadog or Splunk.

• Exposure to static code analysis and application security best practices.

• Comfortable working in Linux environments.

• Team player with excellent communication skills, a collaborative mindset, and a commitment to continuous improvement.

• Bonus: Familiarity with engineering or manufacturing industries.
