Original Advert

ALTIA is a multidisciplinary team focused on delivering advanced data-driven and software engineering solutions that generate measurable impact and enable operational excellence. Working across international environments, we combine cutting-edge technology, modern architectures, and deep business expertise to transform core systems into scalable value. Our mission is to help organizations evolve through digital innovation, cloud-native transformation, and high-quality software engineering, fostering continuous learning, collaboration, and technological excellence.

We are looking for 2 Full-Stack Developers (Java + Angular) with a strong technical background to join our team in a high-impact international initiative.

The Full-Stack Developers will work across two parallel streams: (1) maintaining and evolving existing legacy monolithic Java systems (SEP Submission and eAudit), and (2) leading their progressive decomposition into modern, cloud-native microservices architectures.

In this role, you will be responsible for designing and delivering end-to-end features, writing clean and maintainable code, and implementing robust RESTful APIs documented via OpenAPI/Swagger. You will work closely with cross-functional teams to modernize core architectures, manage database releases, and optimize complex SQL queries. Additionally, you will build and maintain automated CI/CD pipelines, drive software quality through comprehensive unit and integration testing (JUnit/Mockito), and utilize AI-assisted coding tools to accelerate delivery within Agile frameworks (Scrum/SAFe).
