About The Role Accso is seeking an experienced Software Engineer to join its consulting and software development projects.

You will apply AI methods and tools throughout the software development lifecycle, including large language models, agentic frameworks, code generation, and test automation. You will contribute across the disciplines of software engineering, creating well-designed, efficient, and testable code. Working closely with colleagues and customers, you will help shape practical solutions, make informed technical decisions, and support the delivery of reliable software. Depending on project needs, you may work with technologies such as Java, JavaScript, Spring, Kotlin, Maven, Gradle, and JUnit.
